Angel Umeh | Software Engineer

Hi there, I'm
Angel
I build for the web,
and a little bit beyond.

I'm a

A developer somewhere in the middle of the climb: past the tutorials, deep in real codebases. I build human-friendly web and mobile apps across the full stack, tinker with AI integrations, and care a little too much about the small details. Currently looking for the next interesting team to build with, while I ship side projects in the meantime.

Currently Open to rolesFull-time | Contract | Remote | Hybrid

Focus Full-stack webReact / Angular / Node / TS

Also Mobile | AI toolingReact Native | LLM APIs

A developer still learning, but already shipping.

I'm a full-stack developer based in Lagos, working remotely with teams that care about good craft. My day-to-day is mostly TypeScript on the web. React and Angular on the frontend, Node on the backend; though I've spent enough time in Python and mobile (React Native / Expo) to be useful there too.

I think of myself as a mid-level dev: confident enough to own a feature end-to-end, humble enough to know there's a lot of computing I haven't touched yet. I read other people's code. I ask questions. I try to leave a codebase a little tidier than I found it.

Outside work, I'm probably crocheting, pummeling my brothers at Mortal Kombat, or cooking something colorful (no, not lines of code).

FFlorence AI

Co-founder | Solo engineer

Node.jsMongoDBAnthropic APIReactTailwindCSS

An educational assistant that reached 1,500+ students and counting.

Florence AI is a WhatsApp and Telegram chatbot built for underserved students in Africa and Latin America who can't afford private tutoring or paid AI plans. Every architectural decision was mine: the command structure, the payment flow, the database schema. The core question driving every build decision was whether a first-time Telegram user could pick it up without instructions.

It runs on a Node.js / Express backend with MongoDB, with the Anthropic and OpenAI APIs integrated for tutoring and Q&A. The homepage at myflorence.co is React + TailwindCSS.

EEncentral EMS

Frontend developer

Angular 17TypeScriptMaterial UIAngular CDKSCSS

An internal tool that replaced spreadsheet chaos for a whole department.

At Encentral Solutions, I picked up the company stack: Angular (with the old modular component architecture, at a time when Angular had already moved to standalone components) and SCSS with Material UI and built their internal employee management system. Role-based access control, drag-and-drop kanban boards via Angular CDK, attendance tracking, leave management, and data-driven dashboards for both admins and employees.

The system replaced their previous Google Sheets-based task tracking and is currently in active internal use.

RRentWatch

Solo | Hackathon

Next.jsTypeScriptTailwindCSSSupabaseFramer MotionRecharts

A reputation system for Lagos landlords and tenants, built in four days.

RentWatch was a solution built by Team Sibyl (@Dr_Stone and I) for the Enyata × Interswitch Buildathon 2026. If you've seen Psycho Pass, it's basically the Sibyl System, but for Lagos real estate. Landlords and tenants both have a Hue Score reputation system that tracks reliability across lease periods, and each side gets a separate role-based dashboard.

RentWatch is still in development, but right now has a full PostgreSQL schema + RLS, animated dashboards with Framer Motion and Recharts, a mock lease and payment management flow using Interswitch APIs.

GGuessing Game

Solo | Full-stack

Socket.ioTypeScriptReactViteSupabaseVitestRTL

Real-time multiplayer, tested end-to-end, plays best with four people.

A live word-guessing game with session management, reconnection handling, live game state broadcasting via Socket.io, countdown timers, and player disconnect cleanup. Frontend components are tested with Vitest and React Testing Library while the backend is covered with Jest.

A simple coursework project replaced Monopoly at game nights with my brothers. Honestly, it's a fair metric of whether a game actually works.

My toolbox, today.

Things I've actually shipped.

Notes I've published.

Things I love when the laptop closes.

The slowest kind of debugging.

Music with real architecture.

Pummeling my brothers, barely as fun as getting fatalitied myself.

Creativity locked behind the paywall of meal prep.

The other place I compile stress.

A handful of quieter ones.
