Most of my work goes beyond writing code. I help plan the architecture, make technical decisions, and build products from end to end. Whether it's the frontend, backend, cloud infrastructure, databases, or AI integrations, I'm comfortable owning the entire development process. My main stack is React, Next.js, Node.js, NestJS, Python, PostgreSQL, MongoDB, and AWS. Over the past few years, I've built SaaS products, internal tools, AI-powered applications, dashboards, APIs, and automation systems. I use AI every day as part of my workflow. It's a tool that helps me prototype, research, automate repetitive work, and ship features faster, but I still spend time making the right architectural decisions, reviewing the code, and making sure the final product is something I'd be comfortable maintaining. I like working on projects where I can contribute beyond writing code. Whether it's planning the architecture, improving performance, simplifying a complicated system, or helping choose the right technologies, I enjoy solving problems that make the product better. If you're looking for someone who can take ownership of a project, communicate clearly, and build software that's made to last, I'd be happy to chat.
