Software Engineer II with 5+ years building and scaling SaaS platforms, ERP systems and AI-integrated products. I don't just write code: I own systems, make architecture decisions, and ship things that run in production for tens of thousands of users.
🔭 Currently owning the AI layer and release engineering at weDevs 🎓 Pursuing MSc in CSE at BUET 💬 Backend architecture · AI/LLM integration · RAG · Release engineering
- 🤖 AI in production, not demos: LLM features behind a multi-provider abstraction spanning OpenAI, Anthropic Claude and Google Gemini, shipped to paying customers
- 🧠 RAG from the ground up: PostgreSQL with pgvector, embedding and vector-search services, IVFFlat cosine indexes, answers generated over retrieved context
- ⚙️ Backend architecture: systems that hold up under real load, and a 10-20% cut in API response time through backend redesign and query optimization
- 🎨 Legacy modernization: rebuilt a Vue admin in React on a new REST API, and restyled a product line onto a shared design system
- 🚢 Release engineering: 47 tagged releases in 12 months, plus the WordPress.org SVN and GitHub Actions pipelines behind them
- 🔒 Security: patched SQL injection, broken access control, sensitive-data exposure and shortcode-execution bugs across a plugin suite
- 🧩 Full ownership: shipped complete SaaS platforms from scratch: schema, APIs, frontend, deployment
