Problem
The Tracktor SaaS platform required highly performant, reliable, and cleanly architected scalable backend services to manage B2B equipment rental processes. Secure and stable APIs were also essential for seamless collaboration with the frontend and product teams.
Solution
As a Backend Engineer, I built and evolved RESTful APIs using FastAPI, implementing request validation, dependency injection, background tasks, and async endpoints where required. I designed PostgreSQL database schemas and optimized complex queries, indexes, and joins to handle production workloads. I implemented authentication and authorization flows using OAuth2 and JWT, ensuring secure access control. Additionally, I containerized services with Docker and wrote bash scripts to automate backend infrastructure tasks and operational workflows.
Outcome
Code reliability increased and regression issues during feature releases were significantly reduced through the implementation of unit and integration tests using Pytest. Database optimizations improved overall performance under production loads. Close collaboration with frontend developers and product stakeholders ensured that product requirements were translated into smooth and reliable API integrations.
