Apr 2020 - Present • 6 yrs 2 mos

I am a Full Stack Engineer with experience building SaaS products, AI-powered applications, automation platforms, and scalable web systems from the ground up. My expertise spans frontend development, backend architecture, API integrations, authentication systems, AI workflows, and product-focused engineering, with a strong understanding of how startups rapidly build and scale products. I have independently developed multiple SaaS MVPs, handling everything from architecture and development to UI implementation, integrations, deployment, and feature planning. This has given me strong experience in rapid prototyping, scalable system design, and building lean products that validate ideas quickly. My frontend expertise includes React, Next.js, Angular, JavaScript, and TypeScript, where I have built dashboards, analytics platforms, and interactive web applications focused on performance, scalability, and user experience. On the backend, I have developed APIs, authentication systems, and workflow-driven applications using Node.js and Supabase, along with integrating third-party APIs, AI services, and automation tools. I also have experience building AI-integrated applications using modern LLM workflows, as well as interactive 3D dashboard systems and digital twin platforms using technologies like React Three Fiber and Mapbox. Beyond coding, I bring a strong product-oriented mindset with a focus on startup execution, rapid iteration, usability, and building technology that solves real business and user problems.
