Gitesh Sagvekar

About

Full-stack engineer with recent experience at Amgen building an internal healthcare data validation/transformation and workflow automation service: Python/FastAPI backend with REST APIs plus a React UI, designed around a canonical contract-first model to handle inconsistent upstream data. Operates production systems on AWS (EC2/ELB/S3/CloudFront) with strong focus on observability (structured logs, correlation IDs) and safe CI/CD-driven migrations; also has experience shipping quickly in ambiguous environments at TCS.

Key Strengths

• End-to-end ownership of production full-stack features (frontend, backend, deployment/ops)
• Designs stable API contracts via canonical data models and transformation layers
• Layered validation approach with fail-fast schema checks
• Production observability and troubleshooting using structured logs and correlation IDs
• Performance-focused backend/data design (indexes, pagination, avoiding N+1, caching)
• Safe, CI/CD-driven database migration strategy with backward-compatible rollouts
• AWS production operations (EC2/ELB/S3/CloudFront) with reliability and least-privilege IAM
• High-ambiguity execution: quickly gathers user input and ships minimal viable solutions
• Owned end-to-end delivery of production healthcare data validation microservice (design through monitoring)
• Backend API design with auth (token + RBAC), versioning, and standardized error handling
• Built layered validation pipelines (schema + business rules + reference data lookups) with auditability
• AWS production operations: EC2 + ALB, IAM-secured S3 logging/audit trails, multi-environment VPC setup
• Reliability practices: unit/integration tests, structured logging with correlation IDs, health checks, monitoring of error spikes
• Performance/scalability optimization: in-memory caching, stateless services for horizontal scaling, query optimization under load
• Designed PostgreSQL schema for workflow/validation tracking with indexing strategy and iterative tuning via slow-query review
• Delivered React/TypeScript operational dashboard with strong UX handling (loading/error/empty states, filtering/sorting, debounced search)
