I build production-grade systems across web and mobile — from OCR pipelines and trading dashboards to SaaS platforms serving West African businesses. Over 4 years shipping real products in remote-first, cross-functional teams.

"Building visually appealing and helpful projects that facilitate living in the 21st century."

Multi-tenant invoicing and quote platform built for West African SMEs. MTN MoMo payments via Paystack, PDF generation, team management with invite links, and subscription tiers priced in GHS. Deployed on DigitalOcean with a React Turborepo frontend on Vercel.

OCR-driven lab workflow that converts uploaded reports into structured clinical data. Async queue + webhook architecture with fallback handling for delayed or failed extractions. Also built a family tree org chart for tracing patient lineage and hereditary conditions.

Node.js React Bull Queue OCR TypeScript

Custom Node.js script rendering React components to MP4 server-side — eliminating third-party video tools entirely. Engineered card generation and merge pipelines at scale. Led full front-end development from zero to production ahead of launch deadline.

React/Vite analytics platform with HMAC-signed API integration pulling balance, history, and exposure data. Interactive charts for daily P&L, volatility, drawdown, and Sharpe ratio with date-range filtering and risk metrics.

React Vite HMAC Auth TypeScript Recharts

Presigned S3 uploads and CloudFront signed-cookie delivery for protected game asset distribution. Full REST API with JWT/RBAC auth, Swagger docs, PostgreSQL via TypeORM, and processing-status + retry handling.

Built two internal platforms that replaced paid SaaS tools — Trakka (project management, 60% cost reduction) and Tickr (timesheet management, 65% cost reduction). Full-stack features, RESTful API integration, and cross-functional collaboration with UX/UI.

Full ownership, start to finish I've architected, built, and deployed complete products — from database schema and auth layer through to CI/CD and production monitoring. TuaKa went from zero to live at tuaka.org.

AI-integrated workflows OCR-powered clinical data extraction, server-side video rendering, and async document processing pipelines. I build systems where intelligence is embedded, not bolted on.

Cost-conscious engineering Custom tooling that replaced paid SaaS: Trakka cut software costs by 60%, Tickr by 65%. I look for leverage — the solution that solves the problem and reduces overhead.

Cross-functional collaboration Worked remotely with teams across Ghana, Israel, and Northern Ireland. Comfortable in agile ceremonies, code reviews, technical documentation, and mentoring.

Final Year Project: Attendance Checking System using Facial Recognition & Fingerprint Biometrics

Open to full-stack roles and challenging projects.
