Sunshine FC club management platform

Sunshine FC, Port Harcourt

Live

A complete club-management system that replaced WhatsApp lists and a spreadsheet: dues, fines, contributions, live match recording and tournaments, on web and Android.

Read the full story →

The problem

An amateur football club tracked monthly dues, fines and contributions in WhatsApp messages and a shared spreadsheet. Nobody could see who owed what, receipts got lost, and match records lived in people's heads.

What we did

Members log in to see exactly what they owe, pay online and upload a receipt; admins approve payments, record matches live (goals, cards, injury time), run tournaments and export debt reports for WhatsApp or PDF. It runs as a website, an installable app and an Android APK, and stays in sync with the club's existing Google Sheet.

The result

77 members onboarded, 173 releases shipped, and the platform is now offered to other clubs as a branded product (see the live demo).

LightWorld City church platform

Lightworld City Christian Center, Umuahia (4 campuses)

Live

A multi-campus church website with a self-service admin panel, a member app with an offline Bible, and a Pastor App that turns any sermon file into tappable scripture references.

Read the full story →

The problem

A growing church with campuses in four cities needed a site that staff could update themselves, plus tools for members and pastors, without paying monthly for a developer.

What we did

Public website with 17 admin-editable sections (photos, programs, sermons, giving details, even colours); a member app with four offline Bible translations, quizzes and study plans; and a Pastor App that opens PDF or Word sermons and makes every scripture reference tappable. Delivered as two Android apps plus an installable web app.

The result

53 releases, two Android APKs, live on zero-cost hosting with email alerts for every message the church receives.

Marvberth Global product catalogue

Marvberth Global Company Ltd, Port Harcourt

Live

A product-catalogue website for a 16-year-old plumbing and sanitary-wares supplier, with photo galleries, WhatsApp quote requests and a fully self-service admin.

Read the full story →

The problem

A well-established supplier had no online presence. Their product range, and their ISO-style company profile, were only visible to people who walked into the store.

What we did

Ten product ranges shown through galleries of 89 of the client's own photos, a browsable company-profile page, quote requests that open WhatsApp with the product pre-filled, and an admin panel where the owner edits every word, uploads photos and adds products without touching code.

The result

Delivered in two weeks with the client's real photos and official logo. The owner manages the site independently.

Picmoor Luxury online store

Picmoor Luxury, Lagos (two physical shops)

Delivered

An online clothing store built for how Nigerian small businesses actually sell: customers order online, the order lands on WhatsApp, and the owner manages stock and orders from a dashboard.

Read the full story →

The problem

A fashion brand wanted to sell online without card-gateway fees or paperwork, while keeping payment on WhatsApp where their customers already are.

What we did

Catalogue with sizes and colours, cart, and a checkout that opens WhatsApp with the full order pre-typed and a unique order number. The owner gets an instant Telegram alert and manages orders, stock, products and customers from an admin dashboard. Installable on phones as an app.

The result

Delivered with 14 products and running on free-tier hosting; stock is decremented automatically at checkout and restored on cancellation.

Washary laundry booking site

Washary, Asaba

In progress

A pickup-and-delivery laundry site with a five-step booking flow that lands as a ready-made WhatsApp message, plus an admin for prices and service areas.

Read the full story →

The problem

A laundry business needed customers to book pickups without phone calls, and needed to change prices and areas themselves.

What we did

Customers pick a service and plan, choose a pickup slot and enter an address; the booking is sent to the business on WhatsApp. The owner edits prices, add-ons, FAQs and service areas from an admin panel.

The result

Built and ready; launching on the client's domain.

Hope: offline Bible & encouragement app

REYOTECH product

Live

A free Bible app that works fully offline after the first load: four translations, daily devotions, 36 life-situation topics, quizzes and reading plans, installable on any phone.

Read the full story →

The problem

People wanted Scripture and encouragement on their phones without data costs or app-store friction.

What we did

An installable web app bundling four public-domain translations, a daily verse that changes at midnight, topic-based verse finder, a five-level quiz, reading plans, saved verses and read-aloud. Set up for Google Play packaging.

The result

Live and free. A working example of a mobile-first, offline-capable app.

LPG terminal loading & dispatch system

LPG loading terminal, Port Harcourt

In progress

An office-side control system that decides who may load, what, how much and at which bay, and keeps a permanent record of every load, talking directly to the loading-bay batch controllers.

Read the full story →

The problem

Truck loading ran on paper tickets, phone calls and trust. A driver could load the wrong quantity, and there was no reliable record matching what the meter actually measured.

What we did

Built on Ignition Perspective with PostgreSQL: a transaction state machine from check-in to dispatch, six business rules enforced in the database itself, contactless driver cards, and pre-staged recipes written to the Smith Meter AccuLoad IV controllers over Modbus so loading continues even if the office network drops. The plant HMI (tanks, valves, bottling, fire network) was rebuilt into the same application.

The result

Phase 1 built and packaged with a full design specification, installation guide and licence schedule; commissioning is next.

CNG mother station: process & instrumentation consultancy

3 MMSCFD CNG mother station, Akwa Ibom · with Becord Technologies

In progress

Independent technical consultancy on a new compressed-natural-gas mother station: FEED package review, PLC I/O mapping, vendor evaluation and site inspection.

Read the full story →

The problem

The station owner needed an independent engineer to check the contractor's design and two competing equipment offers before committing.

What we did

Reviewed roughly 100 FEED documents across eight disciplines, drafted the PLC I/O mapping matrix and control architecture (process automation, SIL 2 safety system, fire & gas), compared the two vendor offers and flagged six red flags, produced process flow and P&ID drawings, and represented the consultancy at the site inspection.

The result

Client received a clear, plain-English picture of the design, its risks and the questions to put to the contractor before signing.

LPG plant PLC I/O engineering

LPG production & distribution facility

Delivered

Every instrument, valve and motor across the pump shed, loading skids and cylinder-filling area catalogued into a 125-point PLC I/O list ready for programming.

Read the full story →

The problem

The plant's P&IDs existed, but nobody had turned them into the signal list, rack layout and interlocks a PLC programmer needs.

What we did

Tag-by-tag I/O list with signal types, ranges and card/channel allocation, a recommended Allen-Bradley rack layout, safety interlocks per area and a commissioning checklist, exported as CSV for direct import.

The result

125 I/O points (35 AI, 6 AO, 53 DI, 31 DO) across three P&ID sheets, ready for the programming phase.

Bitumen & HFO terminal control narrative

Fuel storage terminal, Port Harcourt

Delivered

A control and automation philosophy for a new bitumen and heavy-fuel-oil terminal, so operations, engineering and the PLC integrator share one description of how the plant should behave.

Read the full story →

The problem

A terminal extension had a P&ID but no agreed description of control loops, alarms, interlocks and emergency shutdown.

What we did

Design-basis tables from the P&ID, a layered control architecture (basic process control, safety system, fire & gas), and control loops, alarms, interlocks and ESD actions per system, generated from a script so revisions are reproducible.

The result

Rev A issued for review covering four 7,602 m³ tanks, four loading pumps and four loading arms.

MV Aquashield I: HMI installation & general-alarm restoration

Offshore support vessel, Port Harcourt · with Becord Technologies

Delivered

Two new Siemens HMI panels supplied, programmed and commissioned into the engine-room alarm system, and three silent lower-deck alarm sounders brought back to life.

Read the full story →

The problem

The vessel's alarm HMIs needed replacing, and three lower-deck general-alarm sounders were not activating, a safety issue for the crew.

What we did

Backed up the project from a working reference panel, restored it to two new SIMATIC KTP400 panels, configured Profinet and power, then traced the sounder fault and fixed it with a relay-based circuit before a full alarm test from the pilot board.

The result

Signed purchase order, three to four days on board, job closed with a signed completion report.

MV Khajan: vessel monitoring system restoration

Security & intervention vessel · with Becord Technologies

Delivered

Two service visits that brought a dead Praxis vessel monitoring system back, including a remote diagnostic session with the overseas manufacturer.

Read the full story →

The problem

Whole module groups of the monitoring system were dead. One faulty field input was dragging the 24 V supply down to 8 V and tripping the distribution switch. Later, a distributed processing unit went down.

What we did

Isolated the supply input by input while monitoring voltage to find the single circuit at fault, set up a secure on-board link for a remote session with the manufacturer to confirm every module was healthy, and on the second visit traced the processing unit to a cable mismatch and blown fuse.

The result

All modules restored and fully functional; broken backup network lines documented for the owner's repair list.

MV Meedoi: control network restoration

Offshore vessel, Port Harcourt · with Becord Technologies

Delivered

A total loss of the vessel's automation control system traced, segment by segment, to a broken server cable and fixed the same day.

Read the full story →

The problem

The crew reported a complete loss of the Praxis automation system with no obvious cause.

What we did

Structured fault isolation outward from the server found a physically broken primary communication cable; a new cable was routed on a secured path and verified end-to-end before energising.

The result

Every network device reporting again and the system handed back fully operational the same day.

Tug, Lagos · with Becord Technologies

In progress

Fault assessment of a frozen bridge AIS display and a damaged aerosol fire-suppression control unit, followed by sourcing and replacement of the fire unit.

Read the full story →

The problem

The right-hand AIS display on the bridge was frozen, and the engine-room fire-suppression sub-station had a damaged circuit board and cabling after engine work.

What we did

Documented both faults in diagnostic reports, sourced a DNV-approved replacement fire unit with fire-rated cabling, and quoted supply, installation, loop testing and commissioning.

The result

Purchase order received; replacement and commissioning scheduled.

Tank level gauges for Power BI

Operations analyst (individual client)

Delivered

Three custom Power BI visuals that show a tank's contents as an animated liquid level inside a sphere, cylinder or pentagon tank, mapped to true volume.

Read the full story →

The problem

The only available liquid gauge visual was abandoned and showed percentage height, not real volume, so dashboards misled readers.

What we did

Rebuilt the visuals on the current Power BI API with correct volume physics for each tank shape, data-bound min/max ranges, K/M/B value formatting and wave animation.

The result

Three installable visuals that coexist in one report, delivered across two iterations.

LPG operator training deck

LPG plant engineering team

Delivered

An 18-page operator training manual turned into a 37-slide teaching deck, with every safety call-out preserved, generated from a script so it can be re-branded or extended.

Read the full story →

The problem

The plant had a good manual but nothing to teach from.

What we did

A reproducible generator that lays out modules, content and colour-coded DANGER / NOTE / KEY POINT call-outs in a consistent theme.

The result

37 slides across five modules; the method is reusable for any SOP or safety manual.
