What I'm looking for

I’m looking for a team where I can build high-performance full-stack products with AI/ML integrations, own system design end-to-end, and mentor others—while shipping secure, scalable features that drive real business results.

I’m a Senior Full Stack Engineer with a strong track record of building 0→1 scalable, AI-driven products across healthcare, e-commerce, and enterprise platforms. I focus on high-performance, secure, and scalable applications that deliver measurable impact.

At Talmate, I engineered backend systems using Node.js and Python, improving system reliability by 55% and enabling real-time predictive analytics. I architected and deployed AI/ML pipelines (TensorFlow, PyTorch), designed modular microservices (Django/Flask/FastAPI/Express/Nest.js), and built interactive dashboards that reduced support tickets by 20%.

I also build complete solutions end-to-end: real-time analytics dashboards (Power BI), REST and GraphQL APIs (Swagger/OpenAPI), and robust CI/CD pipelines (GitHub Actions) with canary deployments to reduce release failures by 20%. I strengthen security with OAuth2, JWT, and RBAC, and I improve observability with logging/monitoring/alerting to accelerate incident resolution.

Earlier, at TempusAI and Netsmartz, I delivered scalable APIs and microservices, optimized performance with caching and query tuning (including Redis), and helped teams ship faster in Agile environments. I’m known for mentoring developers, improving workflows, and aligning technical decisions to long-term business and technical goals.
