Full Stack Developer & Backend Lead

Joined as a full-stack engineer and grew into the backend technical lead for the team's most significant product — a classified e-commerce marketplace used by thousands of active users. Drove backend architecture, API design, and production delivery across multiple applications built for the company and external clients.

  • Led backend engineering for a production classified e-commerce marketplace (conceptually similar to Jiji) — architecting the API layer, database schema, authentication system, and business logic from the ground up.
  • Oversaw deployment and long-term maintenance of the platform, which is actively used by thousands of users in production.
  • Built and delivered multiple full-stack web applications for external clients, spanning e-commerce, business tooling, and internal systems.
  • Established Agile development workflows including sprint planning, code reviews, and iterative delivery — improving team velocity and output quality.
  • Collaborated closely with frontend developers and designers, defining clear API contracts and integration standards that reduced cross-team friction.
