Sanjana Kirthi

About

Backend engineer from Emphasis who modernized legacy, tightly coupled workflow systems into observable, event-driven microservices using Kafka. Led a monolith-to-microservices refactor with shadow traffic, feature flags, canary rollout, dual writes, and reconciliation, and strengthened reliability with idempotent consumers, DLQ/replay, and an outbox pattern to prevent DB/event inconsistency. Strong focus on secure multi-tenant APIs (OIDC/JWT, RBAC/ABAC, Supabase-style RLS) and frontend enablement via OpenAPI and typed client generation.

Key Strengths

• Evolved tightly coupled workflow API into event-driven microservices with Kafka
• Reduced API latency/timeouts by moving long-running work off request threads (202 + status API pattern)
• Reliability engineering: circuit breakers, timeouts, DLQ + replay for recoverable failures
• Designed idempotent consumers to prevent duplicate work on retries
• Implemented outbox pattern to guarantee DB/event consistency and eliminate commit-vs-publish failure mode
• Led monolith-to-microservices migration with shadow traffic/dark launch validation
• Risk-managed incremental rollout using feature flags, canaries, dual-write, and reconciliation
• Deep API design for frontend enablement: strict schemas, consistent error shapes, typed client generation
• Production security for multi-tenant systems: OIDC/JWT/JWKS, RBAC/ABAC, tenant isolation, RLS with DB-backed membership truth
