Kavin S.
Senior Full Stack & AI Engineer | 10+ Years | Web, Mobile & SaaS
I’m Kavin Sharma, a Full Stack & AI Engineer with 10+ years of hands-on experience turning ideas, complex requirements and existing systems into production-ready products. Over the years, I’ve worked across AI, SaaS, web, mobile, eCommerce, fintech, blockchain and enterprise applications, often taking ownership of the complete technical side of a product, from architecture and backend systems to frontend, mobile, integrations and deployment. I’ve worked on everything from AI-powered applications and multi-tenant SaaS platforms to fintech products, trading systems, omnichannel eCommerce platforms and high-scale search systems handling around 5TB of data. My strongest technologies include Node.js, React, Next.js, Python, Django, FastAPI, Golang, React Native, PostgreSQL, MongoDB, Elasticsearch and AWS, along with OpenAI/LLM integrations and modern AI-driven application development. What I bring to a project is not just coding experience. I’m comfortable understanding the business problem, figuring out the right technical approach, making architecture decisions and taking the product all the way to production. Whether you’re starting something new, rebuilding an existing application, adding AI to your product, or dealing with a system that has become difficult to scale, I can step in and take ownership. If you’re looking for someone who can think beyond the ticket, communicate clearly and actually own the engineering, let’s talk.
