Emmanuel Obiechina

Senior Full-Stack Engineer

I build web products that people rely on, from corporate banking tools to hackathon platforms. I care about the parts users never see: clear code, good tests and changes that are safe to ship.

Spec sheet
Problem
Hackathon organizers, builders and investors need one place to run events, judge submissions fairly and find talent through shipped work rather than pitches.
What I built
  • AI matching system in Python that pairs builders with hackathons.
  • JudgeBot: an AI judge agent that scores submissions against organizer-defined criteria.
  • Prize-distribution workflows across $370K in deployed capital.
  • Authentication and session redesign used across 11 global hackathons.

Spec sheet
Problem
Creators who stream to several platforms at once depend on paid, closed tools, and every destination has different ingest requirements.
What I built
  • Co-founded and built the platform as one of 3 contributors (40+ GitHub stars, 15 forks).
  • Solved cross-platform stream synchronization with the Livepeer SDK, fanning a single input stream out to destinations with differing ingest requirements.
  • Built the React/Vite frontend and Express/MySQL backend as a pnpm monorepo.
  • Multi-guest support and browser-based streaming with no client downloads.

Problem
Corporate banking users need approval hierarchies, account management and real-time access to business banking away from the desk, without giving up enterprise-grade security.
What I built
  • Built the React Native app for corporate customers.
  • Transaction initiation and authorization with approval hierarchies.
  • Account management, beneficiary oversight and day-to-day banking operations on mobile.

Internal staff tool: not publicly accessibleCase study for Corporate Banking Admin Portal
Spec sheet
Problem
Sensitive banking operations need strict accountability: every critical action approved by a second person, every role limited to exactly what it may read or change, and every step audited.
What I built
  • Built the platform single-handedly.
  • Maker-checker authorization for sensitive administrative actions.
  • Granular RBAC across 12+ administrative roles, each with distinct read and write permissions.
  • Single and bulk transaction approvals, comprehensive audit logging and session management.
  • Account security controls: locking, unlocking and flagging; corporate onboarding and staff administration.

Stack & practice

Frontend

Interfaces that are fast, accessible and easy to change.

  • Components that are small, reusable and easy to test
  • State that stays predictable as the app grows
  • Accessibility from the start, not as an afterthought
  • Measure first, then optimise performance
  • Layouts that work on any screen size
  • Semantic HTML that search engines and screen readers understand

Backend & data

APIs, data and the services behind the screen, including AI features in Python.

  • Clear API contracts and consistent error handling
  • Data models designed before the code that uses them
  • Authentication and authorisation done properly
  • Caching only where it earns its place
  • AI features with guardrails and human review

Engineering practice

Testing, review and the habits that keep a codebase healthy.

  • Tests at the right level: unit, integration and end to end
  • Small pull requests and thoughtful code review
  • Continuous integration on every change
  • Refactoring as part of the work, not a separate project
  • Documentation people actually read
  • Sharing knowledge and helping others grow

How I work

I start by understanding the problem before I write code. Most bugs I've fixed came from a requirement nobody fully understood, not from a hard algorithm.

I prefer simple, readable code over clever code. The next person to touch it, often me in six months, should be able to follow it without a walkthrough. Small, focused pull requests make that easier to review and safer to ship.

I write tests for the things that would hurt if they broke, and I let them guide the design rather than bolting them on at the end. Code review is where I learn the most, from giving it as much as receiving it.

I use AI tools day to day, but I treat their output like a pull request from a new teammate: I read every line, check it against the requirement, and I'm the one accountable for what ships.
