Fullstack Development

End-to-end web applications from React and TypeScript frontends to Python, FastAPI, and Laravel backends. I handle REST APIs, async job processing, database design, and production deployments.

Cloud & Infrastructure

Serverless systems on AWS using Lambda, DynamoDB, EventBridge, SQS, and Aurora. I also manage Docker containerization, Nginx, Cloudflare, CI/CD pipelines on GitHub Actions and Bitbucket, and have migrated AWS infrastructure between accounts with zero downtime.

03

Integrations & Automation

I build MuleSoft APIs following API-led connectivity patterns, integrate CRM platforms like Zoho and Salesforce, and connect third-party tools like Stripe, WebEngage, and Retool to automate business workflows end to end.

04

Engineering Leadership

Involved in sprint planning, code reviews, and mentoring developers. I lead production deployments, represent the engineering team in technical discussions, and collaborate closely with QA, product owners, and data teams using Agile practices.
