SHAMIR HUSEIN
Engineering Manager | AI-Native Engineering Leader
Jakarta, Indonesia · +62 858-1404-7999 · shamirhusein@gmail.com
Profile
Engineering leader with 8+ years managing teams of 5–20 across fintech, real-time platforms, legal-tech, and conversational AI. Track record of shipping under regulatory and scale pressure: core-banking automation that cut loan disbursement from hours to minutes, a 20-engineer compliance-platform rebuild, and a monolith-to-microservices transition that carried a product into three countries. Hands-on engineering manager: architectural guidance, mentorship, and delivery discipline, with production experience in AI-native workflows — Claude Code and Codex, MCP integration, multi-agent orchestration — alongside ownership of enterprise accounts and infrastructure cost.

Experience
Kata AI — Engineering Manager
- Managed an 18-engineer organization structured into account-owned pods (delivery/FDE, product engineering, data, infrastructure); directly engaged on the Indosat group (3ID, IM3, FTTH) and DPR accounts
- Supported two production migration waves of the WhatsApp chatbot for 3ID and HiFi Air (150K, then 10 million MSISDNs) together with the team — unblocking bottlenecks live during overnight deployment windows; the playbook and experience from those waves made the team's subsequent 30-million-MSISDN deployment after my departure significantly smoother.
- Piloted the build of a next-generation omnichannel CX platform (unified inbox, agent + human handoff) — hands-on development alongside APM; delivered the working foundation through structured handover
- Introduced an AI-native way of work on that pilot: Outline for knowledge, Plane for delivery, Claude Code with MCP against docs, tasks, and code — producing structured QA output and release scorecards within two weeks
- Reduced DigitalOcean infrastructure spend from USD 1,000 to USD 250/month (−75%) through legacy resource cleanup
- Drafted assessment-based development plans with measurable gates for the engineering bench, delivered as part of a structured handover
