Co-founder · CEO

I'm Harishpranav R, a self-taught full-stack developer from Tamil Nadu, India. Most people my age are collecting certifications. I'm collecting production deploys.

As the Co-Founder of DuoStack, I work with an incredible team to build technology products that deliver real value. Today, our flagship platform, CareerCraftAI, is live in production, serving real users with a focus on quality, reliability, and innovation.

The B.Sc in Computer Science is happening in parallel. The shipping never stopped for it.

01 — Present tense

DuoStack isn't a line on my résumé. It's my calendar.

In Tamil Nadu, a tech side usually means joining a service company and maintaining someone else's product. Me and my team wanted the other seat — the one that decides what gets built. So we made it ourselves.

DuoStack is a technology startup where every product is built with ownership and purpose. Every idea, every line of code, and every user experience is our responsibility. As a team, we collaborate to make strategic decisions, solve complex problems, and continuously improve our products.

My half of the CEO seat

  • Defining product vision, strategy, and long-term roadmap across our platforms.
  • Leading full-stack engineering — from architecture and backend systems to polished user experiences.
  • Owning infrastructure, production releases, platform reliability, and delivering a seamless experience for every user.

Co-founded and built with an incredible team.

02 — Flagship case study

CareerCraftAI

careercraftai.in ↗

The problem

India adds millions of freshers to the job market every year, and most get the same three pieces of advice: do certifications, fix your LinkedIn, keep applying. Generic guidance at national scale. Meanwhile employers drown in identical résumés. Both sides lose.

The build

An AI-powered career platform that treats a fresher as a person, not a keyword — guidance, preparation and matching for students, freshers and employers. Next.js and React up front, Node and Express behind it, PostgreSQL through Prisma, Claude and GPT doing the reasoning.

Where it stands

Live in production at careercraftai.in, serving all three sides of the market. The numbers change weekly — mail me for the current ones. I'd rather tell you the truth on the day you ask than print a stale stat here.

"The hard part wasn't the AI. It was making AI output feel trustworthy to a 21-year-old betting their first job on it."

03 — Also shipped

General-Agent

A multi-agent AI system where Claude instances plan, delegate and execute instead of answering one prompt at a time. Built to answer a question I kept circling: how far can orchestration go before it genuinely needs a human? Further than I expected — and the interesting failures taught me more than the successes.

Claude · React · Node.js · FastAPI

ChargeGuard

A native Android app that watches your phone's charging so you don't have to. Small scope, done properly, shipped. Not everything needs to be a platform — some things just need to work every single day.

Kotlin · Android

04 — How I actually work

Three rules I keep re-learning on purpose.

Problem first, stack second.

I don't pick a technology and hunt for uses. I find the thing people tolerate because "that's just how it is" — then build the fix.

AI-native, not AI-dependent.

Claude, GPT and Gemini sit inside both my workflow and my products. The judgment about what actually ships stays mine.

Ship, then sharpen.

One real user on version one teaches more than a month of polishing version zero. Production is the honest reviewer.

Off the clock: cricket, video games, and any strategy game with a tech tree. I like planning ten turns ahead. It shows.

06 — Beyond the terminal

Cricket is the other thing I put 200% into.

I'm a batting all-rounder. Selected for the Under-16 district team — not as a formality, as someone who earned the seat the same way I earn anything: by showing up and being better prepared than expected.

The overlap with how I build software isn't metaphorical. Reading a pitch, adjusting mid-over, knowing when to defend and when to attack — it's the same mental model I use in production. Strategy games trained the same muscle. Cricket made it instinctive.
