مرحبًا، أنا
Md Obydullah
Senior software engineer. I ship software that has to stay up when real users hit it.
9+ years shipping production systems. Lately I'm wiring AI into real products. I care about what works, not what looks good in a deck.
Latest projects
Production systems, not side-project demos. The stack, the constraints, the numbers.
Merchant Center Feeds Sync
Go microservice on AWS EKS that syncs ~520K product entries to Google Merchant Center. Replaced a slow Laravel cron with a quota-aware, batched, real-time pipeline.
Provider Price Sync
Go microservice that keeps a storefront showing the cheapest available price per SKU across multiple external supplier APIs. Routes customers to the lowest price automatically.
Pulse · Internal AI Agent
Internal multi-platform AI agent. Business users ask natural-language questions in Discord and get live data from internal APIs via OpenAI tool-use.
Stories from Real Systems
