At DukanBuddy, I engineer operational modules for inventory, billing, sales, and supplier management, handling 10,000+ daily records with sub-200ms API response times. I also optimized MongoDB reporting and invoice generation, improving their speed by 40%.
I architected an offline-first PWA with Service Workers, IndexedDB, and Dexie.js so catalog operations can continue offline and synchronize when the network returns. At DukanBuddy, I also configured CI/CD deployments using GitHub Actions and AWS infrastructure.
At Nexthoughts Software, I developed responsive client interfaces and Node.js/Express.js REST APIs with JWT authentication and role-based access controls. I also optimized MongoDB schemas and implemented automated tests that brought coverage to 80% before staging rollouts.
At FunctionUp, I engineered backend microservices and REST endpoints, and integrated AWS S3 presigned URLs for file handling. In my projects, I built an RAG customer-support platform with pgvector and LangChain.js, and a distributed task scheduler using Redis and PostgreSQL.
