Architecture and delivery

I build thingspeople use.

I'm Dhruv Kumar, a Full-Stack Developer from India. I don't just write code — I architect, ship, and scale production systems that real users depend on.

In Feb 2026, I co-founded ATS FastScan and led all engineering end-to-end — from system design to LLM integration, payment systems, and deployment. My co-founder Aaditya handled data analytics strategy. The product hit 140+ active users in 60 days and got featured on Product Hunt.

Before that, I delivered 10+ production applications for clients across India and Australia — SaaS, e-commerce, hospitality, B2B — all with 95+ Lighthouse scores and full lifecycle ownership from architecture to CI/CD.

I'm AWS Certified, remote-ready, and comfortable with async international delivery. Currently open to full-time roles and serious client projects.

Current MVP-ready builds and a fresh redesign: AI-assisted where useful, but shaped through system logic, product flow, and implementation decisions.

AI changelog generator

ProblemDevelopers ship commits that make sense technically, but those commits rarely become clear release notes for users.

SolutionAn AI changelog workflow that turns GitHub commit history into editable, user-friendly release notes and publishes them as GitHub releases.

HowBuilt a Next.js app with GitHub OAuth, repository selection, commit comparison by release tags, Gemini-powered changelog drafting, editable review flow, GitHub release publishing, and Netlify deployment configuration. AI helped accelerate parts of the build, but the repository logic, API flow, and product workflow were understood and directed deliberately.

HowBuilt with Next.js, TypeScript, Tailwind CSS, Supabase caching, Gemini API roadmap generation, YouTube Data API video discovery, Zod validation for AI structure, and reusable resource cards, tabs, and timeline components. AI was used as a build accelerator while the logic, validation, caching, and user flow were reviewed and directed step by step.
