What I'm looking for

I seek a remote-oriented role building scalable, cloud-native SaaS or AI products where I can own full-stack features, apply LLM integrations, and help drive product and infrastructure reliability and growth.

I am a Full Stack Developer with seven years building and scaling FinTech, Healthcare, and AI-powered SaaS platforms using React, Next.js, Node.js, and Python (Django/FastAPI).

I design and implement RESTful APIs, microservices, and cloud-native systems on AWS and Azure, leveraging Docker, Kubernetes, and CI/CD to achieve 99.9% uptime and faster delivery cycles.

I have integrated LLMs and generative AI—using OpenAI APIs, LangChain, and LangGraph—to automate workflows, introduce AI agents, and improve response accuracy and operational efficiency across production products.

I thrive in remote-first, fast-paced startup teams, collaborating with founders, product managers, designers, and data scientists to drive products from concept to scale while emphasizing ownership, test-driven development, and measurable impact.
