Inside the mind of

Goutam Kumar

Full-Stack Developer & AI Engineer I build scalable, data-driven web apps with Next.js, AI & modern systems

Hi, I'm Goutam.

7+ years designing digital experiences, products and interfaces. Currently leading Product Design at upGrad, where I work across product, strategy, systems, AI and design culture.

I build

systems.

Schemas become APIs. Components become interfaces. Clean code becomes scalable systems a team can depend on.

269+ Solved.

Algorithms, Data Structures & Full-Stack Craft.

I build scalable, data-driven web applications from scratch.

From relational schemas in Supabase and PostgreSQL to high-performance Next.js frontends and Gemini API integrations, I ship applications engineered for reliability and real-world impact.

Strong algorithms foundation with an obsession for clean UI/UX.

269+ LeetCode problems solved across trees, graphs, and dynamic programming. I combine rigorous algorithmic problem-solving with responsive, modern interfaces that feel fast, intuitive and delightful.

I design for inclusion.

Not because it's on a checklist, but because the most interesting design problems live at the edges, not the centre.

These days I'm also in the code.

Prototyping faster, helping designers push PRs, shipping alongside engineers. Not because it's trendy, but because the seam between design and engineering is where the craft either holds or falls apart.

I'd rather be standing there when it decides.

I don't believe in polite decks that protect average ideas.

I don't believe in vanilla.

I believe in things with a spine: products that are unmistakably themselves, built by people who give a damn about the details no one asked them to care about.

That's what I make.
That's what I lead.

If you're building something that deserves to be remembered, let's talk.

I'm open to building brands, designing experiences and good conversations over a cup of coffee.

Based inGreater Noida.

Rajasthan roots, Greater Noida by address (Bennett University). When I’m not writing full-stack code or solving algorithmic problems on LeetCode, you’ll find me exploring applied AI, LLM architectures, and building modern web apps.

Selected work

A few scalable platforms, AI systems and research projects I’ve engineered, from hackathon-winning apps to production storefronts.
