Backend Engineer

Newdich Technology

Software, IoT and cybersecurity company with offices in Abuja and Okitipupa.

• Build and maintain backend services in Node.js and TypeScript as part of the engineering team.
• Design the APIs between services and the data behind them, so other engineers can build on them safely.
• Designed and built the company website to a written design specification.

Zudojs

Open-source TypeScript framework that gives a backend project a ready-made foundation.

• Provides the parts most backends rebuild every time: dependency injection, configuration, logging, events, database access, queues, storage, security and multi-tenancy.
• Starts and stops services in the right order, so an app never closes a database connection while something still needs it.
• Includes a CLI that generates new full-stack projects. BetNG and Scriptune are built on it.

BetNG

Virtual football platform where every match is simulated once and shown identically on web, mobile, TV, shop and admin apps.

• Splits the platform into independent TypeScript and Python services for matches, betting, wallets, settlement, odds, risk and analytics.
• Makes results impossible to tamper with: betting closes before kick-off, outcomes come from a secret server seed, and the database refuses edits to finished results.
• Keeps money exact by storing every amount in whole kobo, and pays out at the odds recorded when each bet was placed.

ProofLens

Checks whether the documents you attach actually support the claim you are making, on web and mobile.

• Compares numbers, dates, names, negation and causation with fixed rules before any AI model is asked, and lets those rules overrule the model.
• Validates every passage the model cites against the stored page, so it cannot quote a sentence or a page that does not exist.
• Runs on Groq, Gemini, NVIDIA NIM or Ollama behind one interface, and shows an error with a retry when reasoning is unavailable instead of inventing a verdict.

SentinelX

Self-hosted intrusion detection and prevention for homelabs and small offices.

• Watches live network traffic or packet captures and detects port scans, brute-force logins, floods, DNS abuse and custom rule matches.
• Groups related alerts into incidents and gives each a 0–100 risk score with the reasons behind it.
• Can block an attacker through the host firewall, but only after an administrator switches blocking on, and never against protected addresses.

CommitGuard

Stops AI coding agents from being credited in Git commits where a project's policy forbids it.

• Checks commits on the developer's machine, in pull requests through a GitHub Action, and across an organisation through a GitHub App with a dashboard.
• Sees through disguised names, such as look-alike letters or invisible characters, that a plain text match would miss.
• Reads its policy from the main branch, so a pull request cannot switch off its own check. Published on PyPI and the GitHub Marketplace.

Scriptune

Listens to a hymn or a Bible verse and tells you what it is, on web, iPhone and Android.

• Turns speech into text with Whisper, on a self-hosted server or on the phone itself, and never keeps the recording.
• Matches misheard or partial lines against seven Bible translations, including Yoruba, and 1,200 hymns.
• Works offline, including search and listening, for use in church with no signal.

Kolo

Digital platform for Ajo and Esusu savings groups, with payments through Nomba.

• Records every contribution in a double-entry ledger, so each member's balance can be traced to the payments behind it.
• Confirms each payment directly with Nomba before crediting a wallet, so a forged notification cannot create money.
• Runs payouts, reminders and notifications in the background so the app stays fast.

Lead Engineer

Telente CBT

Computer-based testing platform for schools and universities.

• Runs timed exams with questions shuffled for each candidate, across four question types.
• Generates exam questions with AI through a separate service that students can never reach directly.
• Serves many schools from one platform, each with its own exams, students and billing.

Church Management System

Records system and public website for a church in Okitipupa, Ondo State.

• Manages members, households, attendance, income and expenses, plus the announcements and gallery on the public site.
• Gives each staff member only the access their job needs, logs every change, and can sign anyone out instantly.

PowerWatch

Lets people report in one tap whether power is on or off where they live, and alerts their neighbours when it changes.

• Built the API, the Android and iPhone app and the landing page. It began as the backend of an Orange internship team project.
• Decides a neighbourhood's status from the majority of distinct people who reported in the last 30 minutes, so one wrong report cannot flip it.
• Places every report in a location hierarchy from state down to neighbourhood, so the same data answers street-level and state-level questions.
