Full-Time
Built production backend microservices for healthcare platforms, turning provider and operational needs into maintainable FastAPI APIs and service logic. Designed REST endpoints with Pydantic validation and OpenAPI contracts, implemented asynchronous workflows with asyncio/background workers, and optimized PostgreSQL data access via SQLAlchemy. Added Redis-based caching and workflow coordination, containerized services with Docker/Docker Compose, and supported CI/CD with GitHub Actions. Used Sentry and OpenTelemetry for debugging across service boundaries and performed code reviews for reliability and maintainability.

Full-Time
Developed Python and FastAPI microservices for advertising and analytics workflows, delivering clear REST API contracts to frontend and integration consumers. Implemented PostgreSQL models with indexing and query optimization, added Redis caching, and used Celery with Redis to handle asynchronous notification and event-processing workloads. Applied repository and microservice/event-driven patterns to keep business logic modular, and packaged services with Docker and Docker Compose. Maintained CI/CD with GitLab CI/CD and collaborated on Kubernetes-based deployments, observability, and production troubleshooting.

Full-Time
Built backend services for e-commerce, retail, and real-estate domains, including product/catalog, inventory, listings, and customer/lead workflows. Implemented REST APIs with FastAPI and Django REST Framework, and designed PostgreSQL/MySQL schemas with indexing and query optimization. Integrated Redis caching for frequently accessed catalog and listing paths and added Celery workers for scheduled processing, integrations, and notifications. Followed Clean Architecture and repository patterns, containerized services with Docker/Docker Compose, automated delivery with GitLab CI/CD, and expanded Pytest coverage for safer releases.

Full-Time
Developed Python backend services for fintech payment, transaction processing, reconciliation, and financial reporting workflows. Built REST APIs using Django REST Framework and later FastAPI-style patterns, focusing on reliable validation, access control, and audit logging for sensitive operations. Implemented PostgreSQL/MySQL data-access layers with SQL/ORM tooling, and added Redis/Celery jobs for asynchronous notifications and scheduled reconciliation tasks. Containerized services with Docker, maintained Jenkins-based CI/CD with Pytest tests, and supported debugging and production issue resolution in collaboration with engineering and QA.
