Vinayak Kumar, software engineer building software since 2020.

I build frontend-heavy full-stack products with React, Next.js, and TypeScript: dashboards, CMS workflows, commerce and ed-tech surfaces, APIs, analytics, and applied AI features where they improve the workflow.

  • React / Next.js / TypeScript
  • Full-time / internship roles
I ship product systems
that move from
prototype to production.
01
The Premise

Three-plus professional years across full-stack products, ed-tech, commerce, AI, and internal tools.

The throughline is product engineering: dashboards teams can act on, mobile surfaces children can navigate, CMS workflows non-technical admins can operate, and RAG flows users can inspect.

What I care about: retrieval with visible evidence, state that does not collapse under product complexity, analytics that explain friction, and code teammates can read months later.

02
The Method

Full-stack because useful products need more than screens.

I build the product layer across interfaces, app state, permissions, payments, credits, analytics events, deployment paths, and AI workflows when the product needs retrieval or automation.

Next.js App Router, React Native, Node, Prisma, MongoDB, Postgres, LangChain, and Flowise are tools. The discipline is shipping small, measuring friction, and making the next iteration obvious.

03
The Outcome

Outcomes that hold up.

Immibot replaced a static intake with an agentic RAG flow: country-specific adapters, eligibility scoring, guest sessions, persisted history, and credit merge.

The BPIT site was built from scratch with inline click-to-edit on rendered pages, persisted via MongoDB. wonderLearn rebuilt its commerce and learning surfaces on Next.js + Shopify GraphQL.

Selected systems.

I'm a React and Next.js software engineer in New Delhi with 3+ years of professional product engineering experience. I started programming in 2020 through Relics leadership and Discord bot systems, then moved into web apps, mobile apps, dashboards, CMS workflows, APIs, and applied AI systems.

Open-source contributor: checkstyle, Express codemod, Jenkins plugins.

Currently pursuing B.Tech in CSE at GGSIPU. In 2025 I led a 3-person official college tech team project at BPIT, building the new site from scratch with Next.js App Router and inline click-to-edit CMS workflows.

At RemoteHire, I re-architected Immibot around LangChain, Flowise, agentic RAG, weighted eligibility scoring, Clerk, Stripe, PostHog, guest sessions, persisted chat history, and credit merge.

At Wonderhood, I spent 2.5 years across React, Next.js, and React Native: Shopify GraphQL commerce, a kids' learning app migrated from Ionic to React Native, and a teacher dashboard with cohort reporting.
