About

Backend engineer who built and migrated a large-scale document intelligence platform used by legal, healthcare, and insurance clients, processing millions of pages. Experienced moving from a monolithic, LLM-heavy approach to a modular FastAPI service architecture with ML classification + RAG, strong validation/auditability, and enterprise security (JWT/OAuth, RBAC, PostgreSQL RLS) with zero-downtime incremental rollouts.

Key Strengths

• Designed and evolved large-scale document intelligence backend handling millions of pages
• Architected modular/service-oriented backend separating ingestion, parsing, ML classification, LLM/RAG reasoning, and validation
• Cost/latency optimization by reducing indiscriminate LLM usage with confidence scoring and fallback logic
• Built enterprise-ready, deterministic and auditable validation/post-processing layers
• Led low-risk monolith-to-modular migration using feature flags, parallel run, gradual traffic shifting, and rollback readiness (no downtime)
• Production-grade API reliability/security practices (strict validation, async performance, retries/timeouts, idempotency, JWT/OAuth, RBAC, rate limiting, secrets management)
• Implemented defense-in-depth data security with PostgreSQL RLS as a hard boundary
• Proactively identified and mitigated document-processing edge cases to prevent silent failures
