Akshith Kumar Reddy Balappagari Gnaneswara

About

Backend engineer who has designed and evolved high-traffic event/activity management systems using Node/Express and PostgreSQL, prioritizing scalability and reliability with a layered architecture. Has led zero-downtime refactors/migrations using parallel runs, dual writes, and rigorous validation/monitoring, and brings a security-focused API approach (JWT, RBAC/ABAC, rate limiting, DB-enforced tenant/RLS filters).

Key Strengths

• Designed scalable, reliable REST backend with clear layering (API/service/data)
• Pragmatic architecture tradeoffs (monolith vs microservices) to reduce ops overhead and ship faster
• Scaled system for high concurrency; added caching/pagination/advanced filtering with minimal refactor
• Led zero-downtime refactor/migration using parallel run, dual writes, read validation, and incremental rollout
• Strong data integrity and risk management practices (backfills, automated tests, monitoring, rollback paths)
• Handled migration edge cases/race conditions via idempotency, versioning, and event logs
• Production-grade API security approach (JWT, scoped permissions, RBAC/ABAC, rate limiting)
• Improved robustness by catching input/contract edge cases; introduced schemas and contract tests
