Hausek • Abuja, Nigeria

Identified a gap in affordable urban housing and roommate matching in Nigeria, and initiated the end-to-end development of a backend system to bridge discovery, safety, and compatibility for shared living. Engineered a secure FastAPI backend from the ground up, balancing rapid iteration with long-term scalability. Users could seamlessly register, create property/roommate listings, and chat securely — all without sacrificing privacy. • Identified a gap in affordable urban housing and roommate matching in Nigeria, and initiated the end-to-end development of a backend system to bridge discovery, safety, and compatibility for shared living. • Engineered a secure FastAPI backend from the ground up, balancing rapid iteration with long-term scalability. Users could seamlessly register, create property/roommate listings, and chat securely — all without sacrificing privacy. • Designed a user-centric roommate recommendation engine, combining lifestyle tagging, heuristics, and unsupervised ML clustering to match users by compatibility, not just proximity — improving engagement and trust in matches. • Built robust OTP-based identity verification to prevent spam and impersonation, while also creating a fallback encrypted email flow for users with poor device access or network inconsistencies. • Developed a real-time chat system with end-to-end encryption and automatic key fallback mechanisms, so that even users unfamiliar with privacy tech could confidently communicate in a secure environment. • Prioritized user trust by embedding encrypted session flows, handling token expiry, suspicious activity detection, and seamless reauthentication — reducing drop-offs and building confidence. • Created intuitive APIs consumed by the mobile frontend, using async architecture to ensure fast responses on low-bandwidth devices — particularly important for users in high-latency environments. • Collaborated closely with mobile engineers to optimize flows like onboarding, roommate search, and messaging UX, ensuring every backend decision mapped to actual user pain points like friction, delay, or privacy concerns. • Wrote extensive unit and scenario tests with pytest and httpx, simulating edge cases across devices and roles, ensuring reliability in real-world conditions and CI stability across iterations.
