What I'm looking for

I want to build and architect secure, high-performance cloud-native SaaS and AI-powered enterprise products—leading technical design and improving engineering velocity with production LLM, RAG, and agent workflows.

I’m a Senior Full Stack & AI Developer with 11 years of experience designing scalable SaaS platforms, distributed systems, cloud-native applications, and AI-powered enterprise solutions. I specialize in React/Next.js with TypeScript and Node.js, plus production AI application development with Python and FastAPI, including LLMs, AI agents, RAG, semantic search, and vector databases.

Most recently at ARKA TECH SOLUTIONS, I architected and delivered cloud-native SaaS and AI platforms, building agent workflows and developer automation using Model Context Protocol (MCP) and orchestration techniques. I modernized monoliths into microservices (reducing deployment time by 68%), improved API response times by 45% while maintaining 99.9% availability, and strengthened DevSecOps with CI/CD and automated testing (reducing production defects by 38%), partnering across engineering teams to deliver secure software end-to-end.
