Professional Overview

Core platform backend engineer on a multi-tenant enterprise SaaS platform managing thousands of industrial assets, warranty claims, and field-service operations for enterprise clients.

• Architected schema-per-tenant isolation and request-scoped datasource routing, guaranteeing zero cross-tenant leakage across thousands of operations.
• Engineered an enterprise search engine with a custom AST query parser compiled to tenant-scoped Elasticsearch, sustaining <150ms p95 latencies across 1,000,000+ asset records.
• Implemented a declarative state-machine workflow engine that turned custom tenant approval flows into configuration instead of new code deployments.
• Integrated Apache Kafka with the Transactional Outbox pattern and idempotent consumers, eliminating dual-write bugs and ensuring zero lost events during network partitions.
• Conducted deep PostgreSQL query profiling (EXPLAIN ANALYZE), composite index restructuring, and connection pool right-sizing to reduce high-traffic endpoint latencies by ~60%.
• Built production JWT authentication with cryptographic refresh-token rotation and role-based access control (RBAC).
