At Dision Tech LLC, I developed Go microservices and backend APIs, contributing to service boundaries, domain models, and API contracts. I also built event-driven communication with NATS JetStream and gRPC.
I implemented asynchronous processing for long-running jobs, including worker pools, retries, dead-letter handling, and idempotency. I improved service performance with Redis caching, PostgreSQL query tuning, and controlled concurrency.
At Biwoco, I developed Python and FastAPI REST APIs and integrated services including Stripe, Mixpanel, and OneSignal. I also worked with AWS Lambda, DynamoDB, OpenSearch, and ECS/Fargate.
On my Founder Journal - AI Telegram Assistant MVP, I built a workflow that turns text, voice notes, and screenshots into structured journal records. I added semantic retrieval using embeddings and pgvector, along with intent routing for capture, retrieval, advice, and content generation.
