Led end-to-end architecture and solution delivery for scalable full-stack applications using Python (FastAPI), React/Next.js, Node.js/TypeScript, and MongoDB/PostgreSQL. Architected FastAPI microservices with authentication/authorization, Pydantic validation, robust exception handling, and REST API contracts; built React/Next.js UIs with reusable components and performance optimizations. Implemented CI/CD with GitHub Actions, containerized workloads with Docker, and deployed on Kubernetes; standardized AWS environments using Terraform. Improved performance with Redis caching and query/API tuning, established automated unit/integration/API/end-to-end testing, and provided troubleshooting/root-cause analysis for production stability. Collaborated with stakeholders and distributed teams to translate requirements into delivery plans, mentoring engineers through code reviews and architecture decisions.

Led client-facing modernization initiatives migrating legacy web applications toward Python/FastAPI, React/Next.js, Node.js/Express, and MongoDB. Owned feature engineering and application modernization workstreams, including Next.js routing/SSR, reusable React components, and responsive enterprise interfaces. Developed FastAPI services with async processing, dependency injection, Pydantic validation, and authentication; built Node.js/Express middleware and integration workflows. Engineered MongoDB schemas, compound indexes, and aggregation pipelines to improve data access patterns. Automated CI/CD with GitHub Actions and deployed containerized workloads on Azure Kubernetes Service using Docker; introduced TypeScript in selected React/Next.js modules. Implemented Celery with Redis-backed queues for asynchronous processing, added testing with Pytest/Jest/React Testing Library, integrated REST/GraphQL patterns, and monitored telemetry to resolve performance bottlenecks. Managed migrations

Supported Python and Django applications used in regulated pharmaceutical workflows, maintaining business logic, data validation, and secure web functionality. Contributed to React/JavaScript interfaces and supported Node.js/Express services for request handling and internal/external integrations. Configured MongoDB collections and PostgreSQL schemas with indexing, validation, and access controls for regulated data. Maintained FastAPI services with REST APIs, request validation, authentication, structured exception handling, and async processing. Built reusable React components, implemented Redis caching for selected workflows, and supported Kafka event streams for asynchronous integration with downstream enterprise systems. Developed and ran unit/integration/regression/API tests, coordinated CI/CD across validation environments, and supported Docker/Kubernetes deployments with health checks and release readiness. Resolved production issues via log analysis and structured troubleshooti
