I design and ship multi-tenant SaaS, fintech, and marketplace backends, with 4+ years across payments, logistics, realtime systems, and production AI. I also lead a small freelance team, from client scoping through architecture and release.
- ChatboQ at Brahmabyte Technology: a multi-tenant customer-support SaaS with ticketing, omnichannel messaging, realtime calling, and an AI layer
- Built its AI platform: an LLM gateway with per-call cost metering, a RAG knowledge base, an AI answer engine (resolves 35% of conversations), and an agent copilot
- Event-driven infrastructure on Kafka with the Transactional Outbox Pattern for reliable, retry-safe workflows
- Clean Architecture and DDD that keep large codebases easy to change
- Tenant isolation, idempotency, and correctness for anything that moves money
- AI features that are metered, observable, and safe in production, not just demos
