I build software, specializing in backend architecture and data heavy systems. Coming from a Statistics background, I like solving complex logic problems and keeping codebases maintainable. I reach for clean architecture (hexagonal, vertical slices), event driven design, and the C4 model. Other things I spend time on: custom AI agents. For reliability, I use behavioral driven integration tests rather than chasing arbitrary coverage metrics.

Projects

AI Pull Request Orchestrator

July 2026

FastAPI | Modal | Hugging Face (JetBrains Mellum) | GitHub Webhooks | Python

  • • Architected an event driven webhook orchestrator using FastAPI to listen for real-time GitHub Pull Request events and automatically trigger code analysis pipelines.
  • • Offloaded heavy LLM inference to Modal's serverless compute infrastructure, deploying the JetBrains Mellum model (via Modal) to generate context aware code reviews.
  • • Decoupled the webhook listener from the model execution environment, ensuring the API gateway remains highly responsive and avoids timeout failures during long-running inference tasks.

Eventful

June 2026

Next.js | Typescript | PostgreSQL | Redis | BULLMQ | PAYSTACK

  • • Architected a full-stack event ticketing platform with 18 REST endpoints across 5 modules and 12 frontend pages, deployed as a single unit with graceful shutdown handling.
  • • Hardened service layers by implementing behavior driven integration tests across all endpoints, verifying observable state changes and public interfaces instead of relying on fragile internal mocks.
  • • Integrated the Paystack payment gateway using dual path verification webhook first (fast path) with direct API fallback (slow path) ensuring strict idempotency and 0% lost payments from missed webhooks.
  • • Engineered a Redis backed sliding window rate limiter using atomic Lua scripts to eliminate race conditions, utilizing BullMQ worker queues to offload asynchronous notifications.

AI Trading Agent (Quantitative Hackathon Project)

July 2026

Python | Metatrader | Redis | Docker | Pydantic | Linux | Doubleword

  • • Engineered an AI augmented stat-arb system utilizing copula pairs, volatility-targeted momentum, and technical signals, filtered by a Qwen LLM agent to trade 14 instruments across FX, metals, and crypto.
  • • Executed 148 live trades on a $1M simulated account, maintaining strict 0.6% per-trade risk caps, conviction-scaled sizing, and Kalman trailing stops to rigorously evaluate live market variance.
  • • Architected a distributed, end-to-end data pipeline: a worker streamed exchange data via Redis to the LLM on North flank, while Meta Trader executed trades through Wine on a self-managed Kamatera VPS, monitored remotely via Tailscale and Termius.

Real Time Trivia Platform (Guess Game)

April 2026

WebSocket | Node.js | MongoDB | Express | Zod | OpenCode API

  • • Engineered a real-time, multiplayer session management system utilizing WebSockets for low-latency, bidirectional communication between game masters and concurrent players.
  • • Integrated the MiniMax LLM via the OpenCode API gateway to dynamically generate game content on demand.
  • • Hardened the AI data pipeline by authoring strict Zod verification functions to handle LLM outputs, ensuring type safe JSON responses and eliminating downstream parsing failures.

Developer Showcase Platform (Devsearch)

Mar 2025 - Jul 2026

Django REST Framework | Python | Postgres | AWS S3 | REST APIs | JavaScript

  • • Engineered a developer portfolio and networking API using Django REST Framework and PostgreSQL, actively maintaining the production deployment and database health for over a year.
  • • Integrated AWS S3 bucket for user uploads, moving away from local file storage to keep the main application server lightweight.
  • • Detected that Railway's SMTP failures were slowing down the app for new users, and resolved the bottleneck by migrating transactional mail to Resend with custom domain verification.

  • • Built a Google Apps Script workflow that sends daily email reminders for loan payments ahead of due dates.
  • • Maintained cashflow records and spreadsheet books; supported the finance lead on payment instructions.

Backend Engineer

Ventri Ltd | Node | MongoDB | JavaScript | Lagos, Nigeria

Nov 2025 – Jan 2026
  • • Designed and built the Node.js/Express backend for Ventri, a customer and campaign management platform, with MongoDB and REST APIs
  • • Implemented authentication, campaign management, and performance-analytics endpoints so campaigns could be run and measured in one service.
  • • Integrated Facebook API for pulling social media metrics into campaign tracking and reporting.

Backend Engineer

Utopia DAO | Python | FastAPI | MongoDB | Telegram | DexScreener API

May 2025 – Nov 2025
  • • Built a cryptocurrency monitoring backend in FastAPI and Python that ingested live DexScreener market data and sent priority alerts to Telegram.
  • • Designed modular services and caching so the system stayed inside API rate limits without dropping data accuracy.
  • • Implemented High/Medium/Low Telegram notifications, with performance tracking and historical analysis stored in MongoDB.

Intern

Digifigs | Ibadan · On-site

May 2024 - Oct 2024
  • • Analyzed 2 months of user behavior data using Google Analytics, Excel, and Python, compiling findings into reports for the team.
  • • Tested the application across core user flows during QA, identifying and reporting 6 bugs prior to release.
  • • Conducted competitor and market research to explore potential feature directions.
  • • Began self-teaching backend engineering fundamentals (Python data structures & algorithms, Django) alongside this role, laying the foundation for current engineering path.
