At Aiotek, I standardized ERP and marketplace integrations by establishing a reusable backend pattern with Node.js, NestJS, REST APIs, and Swagger/OpenAPI. I also developed and evolved APIs and microservices for Seller Manager.
At Aiotek, I improved invoice synchronization reliability between an external FTP server and backend services, and decoupled invoicing flows using Google Cloud Pub/Sub. I also optimized PostgreSQL and Google Cloud SQL queries and transactions to address production contention and latency.
At Qwavee IT, I migrated a critical agricultural calculation system to NestJS and TypeScript, and implemented a serverless backend on AWS using Lambda, API Gateway, and S3. I also worked on a Drupal 7 to Drupal 9 government website migration, preserving data, permissions, and content structure.
Through Barking Dogs, I co-founded and developed web and mobile products for real clients, including Sinergy Consulting Platform and WatchDog Price Tracker. I also developed Weather API, a project that integrates weather information with an LLM and uses structured outputs, validation, and automated evaluation.
