@martinsnnamchi
I build scalable Django products with high-concurrency database systems.
NigeriaWhat I'm looking for
I've built full-stack products including ShelterTree, a property intelligence platform powered by Python, Django, PostgreSQL, Docker, Render, and HTMX. I designed its PostgreSQL search engine, optimized complex aggregations into single database hits, and built SPA-like live search and filtering with sub-100ms visual updates.
For HitchARide, I built an MVP carpooling platform for African megacities, using database-level locking and atomic transactions to protect seat booking under high concurrency. I've also integrated Google Maps Platform and Mapbox GL JS, built state-management workflows, and created batch-processing scripts for trip expiration.
My work also spans data science and analytics: at SNDBX/The Village Experts, I developed Dash dashboards and revenue forecasting tools, while at Vuti Africa I analyzed M-Pesa datasets and customer sentiment. Alongside engineering, I've completed rigorous technical reviews of 3,000+ scientific and engineering manuscripts and bring a founder's mentality, data literacy, and close attention to detail.
