The cost of poor data infrastructure rarely shows up on day one. It appears when the pipeline lags behind real-time demand, when the automation breaks unexpectedly, when the execution system drifts under load, and other similar failure points. My work focuses on building backend systems that stay reliable at scale, with clean architecture, fast data ingestion, efficient processing, and dependable execution at every stage. If you need a solution built, your business context defines everything from architecture to delivery and you get a system that your team can own, extend, and trust in production.
A WebSocket-driven arbitrage detection system that streams live odds across multiple sportsbooks, matches opposing prices in real time, and auto-verifies opportunities via REST before logging them — with dual-logger observability and Google Sheets persistence.
High-frequency market signal ingestion, feature engineering, and ML model integration served via FastAPI. Pipeline restructuring and lazy loading strategies reduced memory consumption by 70% on AWS EC2.
Constructs dynamic WebSocket URLs across multiple betting markets — match winner, over/under, BTTS, Asian handicap. Manages session lifecycle, reconnection logic, and price reconciliation between WebSocket streams and REST fallback endpoints to guarantee consistency under dropout.
Domain-specific NLP-adjacent matching for a fintech payments backend. Resolves informal, abbreviated, and misspelled Nigerian bank names (GTB, Opay, Kuda, etc.) using a curated alias dictionary and fuzzy scoring, then validates against Paystack's /bank/resolve endpoint in real time.
Production payments layer supporting Paystack and Flutterwave behind a unified interface. Handles full transaction lifecycle, webhook signature verification, idempotency key enforcement, retry logic with exponential backoff, and structured audit logging.
Unattended browser automation targeting MadMarket and Blogabet. Implements persistent session management via storage_state serialisation, automatic expiry detection and re-login, WebSocket price validation before execution, and Google Sheets flushing for audit trails.
Event-driven messaging agent decoupled from business logic via Celery task queues. Dispatches real-time WhatsApp and Telegram notifications on booking lifecycle events with templated rendering per recipient context, retry policies, and delivery failure handling.
