- Led and executed a large-scale Python 2 → Python 3 migration, resolving 120+ critical compatibility and runtime issues, ensuring long-term maintainability and security of the codebase. - Contributed to the architectural design and migration strategy for transitioning legacy APIs to a high-performance Go-based API gateway, focusing on scalability, resiliency, and forward evolution. - Optimized gateway request routing and downstream integrations within a Docker/Kubernetes-based distributed system, improving service availability by ~30% and significantly reducing failover recovery time. - Designed and implemented a proxy compatibility layer that enabled 100% feature migration from Python to Go while guaranteeing forward and backward compatibility, allowing zero-downtime incremental rollout. - Built a production-grade sliding window API rate limiter to protect downstream services, enforce fair usage, and maintain system stability under peak load. - Remediated 150+ Spring Boot security and compliance issues, aligning services with industry security standards and strengthening overall platform posture. - Worked on a task poller framework to ensure eventual consistency of data between databases across nutanix for large clusters.

▪ Designed and implemented an on-demand Kubernetes worker orchestration system to execute large-scale validation suites for Spring Boot services, significantly reducing service downtime and decoupling validation workloads from production runtime. ▪ Built and standardized a Python-driven GitHub Actions workflow to perform static code analysis and enforce unit test coverage gates, improving overall code quality and increasing developer confidence in production readiness. ▪ Architected and delivered a backend service paired with a developer-friendly CLI tool that integrates with multiple internal platforms, streamlining recurring engineering workflows and materially reducing operational friction across teams. Tech Stack: Python, Go, Java, Docker, Amazon ECR, GoCD (CI/CD)

▪ Architected and implemented a high-performance backend service capable of generating dynamic mocks across multiple protocols and data formats, including SOAP, JSON, HTML, Protobuf, RPC, gRPC, and GZIP. The platform supports advanced capabilities such as latency simulation, ultra-low-latency caching, request recording and replay, Protobuf decoding, and unified mock generation driven by a single OpenAPI specification or Postman collection. ▪ Designed and built a scalable proxy abstraction layer supporting heterogeneous clients (Web, iOS, Android, Android LR), enabling seamless integration of dynamic mock services into automated test suites while providing centralized request tracking and observability.. Tech Stack: Python, Go, Java, Docker, Amazon ECR, AWS, GoCD (CI/CD)

▪ Designed and scaled a robust automation testing framework, significantly improving integration and load test coverage while increasing overall reliability and confidence in the codebase. ▪ Architected and developed a backend analytics platform using FastAPI to aggregate developer productivity and activity signals from multiple systems (Jira, Grafana, and internal services), delivering actionable insights through a centralized dashboard to support data-driven engineering decisions. Tech Stack: Python, FastAPI, Selenium, HTML, JavaScript, Docker, Amazon ECR, Jenkins (CI/CD)
