Founding engineer working across mobile, web, and the backend that connects them — consumer apps, the operator dashboards that keep them running, and the infrastructure in between. Currently Founding Engineer at Leeta Technologies.
Cross-platform mobile apps engineered for resilient offline transactions in emerging market conditions.
Real-time management dashboards for operators handling bookings, approvals, and high-cadence controls.
Continuous integration, store build automation, and version gating via fail-open Remote Config.
I've run mobile engineering, CI/CD, and architecture decisions end-to-end for a live marketplace — not just shipped features on a ticket. If you need someone to take technical ownership, not just write code, start here.
See roles held →Websites, web apps, mobile apps, or the two-sided platforms most builders skip — the operator dashboard that makes the consumer app actually work. Scoped, shipped, and handed off clean.
See projects →Where I've been the person accountable for the decision, not just the person who implemented it.
Lagos-based LPG delivery marketplace. Own mobile engineering across the consumer and vendor apps, CI/CD infrastructure, and architecture and team-standard decisions as the company scales past MVP.
Multi-tenant business administration platform for hospitality and service operators. Built the event-management and reservation tooling operators use to run real-time analytics, approvals, and business operations from one dashboard.
Real-time commodity price-tracking app built for low-connectivity conditions: custom interactive UI, offline caching and sync, and Firebase-powered notifications so pricing stays usable without a stable connection.
Bilingual university LMS with video progression, quiz evaluation engine, and automated certificate issuance. Designed responsive UI with RTL support, admin dashboard with analytics, and verification system.
Personal and professional projects where I made the architecture call, not just the interface.
Offline-first audio logging app for lecture media volunteers.
Offline-first classical text memorization app with loop audio drilling and PDF study.
Qur'an memorization tracker with teacher and family modes.
Islamic edtech and Arabic-language tooling I build outside of client and employer work — same rigor, no brief.
Offline-first audio logging app for lecture media volunteers, i18n across four languages with RTL support.
Qur'an memorization tracker with teacher and family modes, Supabase backend, real memorization-cadence scheduling.
Arabic dictionary app unifying Lane's, Al-Qamus, and Arramooz into one FTS5-searchable schema.
Specific decisions from real projects — not general advice.
Three buckets, not one hammer: force what's unsafe to leave, nudge everything else, and fail open when the update-checker itself can't reach the network. A version gate driven by Remote Config, and the release loop that keeps the gun holstered.
The first ten minutes of a slow-API investigation should be one command, not a meeting. The curl one-liner that turns 'it feels slow' into a number you can actually argue with.
If a bug traces to a bad assumption three layers down, I fix the assumption — not the symptom in front of me.
Boring, well-known principles, applied consistently instead of cleverly. Most production pain comes from skipping them once.
I hand back working files, not partial patches someone else has to reconcile in their head.
Nigerian SME workflows, Paystack, WhatsApp-native patterns, low-connectivity conditions — designed in from the start, not patched on after.
I'm Abdulmuiz Abdulwasiu, a founding engineer at Leeta Technologies, a Lagos-based LPG delivery marketplace. My work spans mobile engineering in React Native and Expo, frontend web development in React, backend and API work when a project needs it, and CI/CD infrastructure — plus the architecture and team-standard decisions that come with owning a product end to end rather than a single feature of it.
Outside of that, I build Islamic education technology — memorization tools, Arabic lexicography software, and offline-first apps for da'wah media volunteers — with the same engineering discipline I bring to production work: root-cause fixes, DRY and KISS applied consistently, and software built for the market it actually ships into.
I also run Opticrafts Atelier, a small leather goods brand based in Lagos — a different kind of craft, same attention to how things are made.
