At TechVortex Ventures, I build and maintain Spring Boot APIs for Keypr, a consumer dating product live on Android and iOS.

I develop registration, login, profiles, photo uploads, preferences, user discovery, swipe actions, and mutual-match detection. I use MongoDB for profiles and interaction history, including aggregation pipelines, indexes, and geospatial discovery filters.

I improved average API response time by approximately 30% through query and service-layer optimisation, and reduced integration bugs by approximately 40% by standardising DTOs and layered backend design.

I secure endpoints with Spring Security and JWT, manage media through AWS S3 pre-signed URLs, containerise services with Docker, and support API testing, documentation, production fixes, and cross-functional delivery with frontend and QA teams.
