ABHINIT KUMAR

Hi, I'm Abhinit.

Full Stack Developer building scalable, intelligent digital products.

I build web applications from frontend to backend, combining thoughtful user experiences, robust APIs, efficient databases, and AI-powered capabilities.

Currently, I work on multi-tenant SaaS platforms, data integrations, and AI-assisted workflows, with a focus on clean architecture, performance, and maintainable software.

Away from the keyboard, I enjoy playing Two chess pieces on a board and Airplane flying through the sky.

About

I'm a full stack developer with four years of experience designing and building scalable web applications. My day-to-day work spans React and Next.js on the frontend, NestJS and FastAPI on the backend, and PostgreSQL or MongoDB underneath.

I started in 2022 as a developer intern and moved into a full-time MERN role based on performance. Since then I've worked on API design, authentication and role-based access control, query optimization, and multi-tenant architectures.

These days a lot of my work sits where product engineering meets AI: data integrations, chat assistants over analytics, and tooling that fits into how developers already work. Outside of work, I play chess and like to travel.

Projects

AI Marketing Analytics SaaS

Aug 2026 – Present

Marketing performance lives in separate tools, which makes SEO, revenue, and channel results hard to read together.

What I built

  • A multi-tenant analytics platform that unifies GA4, Search Console, Ahrefs, Shopify, and paid channels.
  • Secure tenant authentication, data-source integrations, and interactive dashboards.
  • AI-powered insights for SEO, revenue, and channel performance.

Key decision

Multi-tenant from the start, with per-tenant authentication and integrations feeding shared dashboards.

  • FastAPI
  • PostgreSQL
  • OpenAI
  • MCP
  • GA4

DevPal

Aug 2026

Developers work across several repositories, but managers want a clear daily narrative rather than raw commit logs.

What I built

  • A Next.js and TypeScript app with MCP and CLI tooling that generates daily engineering status reports from Git commit history and uncommitted work.
  • Repository-to-project mapping, SQLite persistence, and scheduled email delivery of manager-ready reports.

Key decision

Local-first: reports are written from Git evidence through MCP tools, stored in SQLite, and emailed on a schedule.
