Dedicated Product Engineering

Abin re-engineered our daily reconciliation batch processor from the ground up. He implemented row-level pessimistic locking and idempotent ledger events that completely stopped duplicate ledger postings during bank network timeouts. Working directly with him saved us months of coordination overhead.

Zero ledger discrepancies across 25,000+ daily bank settlements; P95 batch runtime dropped by 78%.

Fixed-Scope Milestone

We needed a production RAG system that respected document-level access permissions. Abin designed a hybrid vector and keyword search pipeline in PostgreSQL using pgvector, complete with citation chunking and guardrails. He delivered clean code, thorough documentation, and met every milestone ahead of schedule.

Multi-tenant RAG search launched in 6 weeks with sub-800ms response latency and 100% RBAC permission enforcement.
