What I'm looking for

I seek a full-stack role building cloud-native SaaS and AI-driven products where I can architect scalable systems, collaborate with product/UX, and drive measurable cost and performance improvements.

I am a full-stack software engineer focused on building cloud-native B2B SaaS and AI-enabled solutions, blending frontend, backend, and infrastructure expertise.

In my current role I architected a full-stack platform using React, TypeScript, Three.js, Flask, and AWS, designing scalable APIs and data pipelines that delivered 25% cost savings and reduced storage costs by 57% through migration to S3 and AWS Glue.

I collaborated with AI engineers to build an LLM+RAG chatbot that achieved 85% response accuracy and deployed generative-AI labeling workflows that increased labeling speed by 67% while maintaining 90% accuracy.

Earlier I built frontend components serving millions of users, developed Spring Boot microservices processing thousands of daily transactions, led incident responses, and authored technical documentation and training that improved onboarding and operational response times.
