Product engineer, Kolkata

Hi, I'm Atri. I build products
and the infra under them.

I'm a product engineer who likes to find the actual problem before writing a line of code — then ship something small, watch real people use it, and fix what's broken.

Three years at Crio.Do (two promotions along the way), most of it spent somewhere between the product spec and the deploy log. Lately that means LLM features that earn their keep, autograders that don't lie, and infra that gets out of the way.

01 Selected work

AI Interview Assistant

Crio.Do · 2025

Parses a resume, runs a contextual interview, and scores it — the prototype that shaved two months off the internal rollout.

PromptBuilder

Crio.Do · 2025

A pipeline that stitches backend metadata and a learner's own project work into prompts. Took the build from six weeks to two.

FormulaAI

Bootstrapped · 2025

AI-driven JEE prep, solo-built. FastAPI orchestrator between LLMs and the platform, deployed on a three-cloud stack.

02 Where I've worked

Associate Product Manager

Crio.Do · Bengaluru

May 2025 — Present

Took the AI features from "cool demo" to something the team actually relies on.

2 mo earlier rollout6→2 wk build+24% completion8.7 NPS
  • Built the prototype for an AI Interview Assistant — LLM resume parsing, contextual interviewing, evaluation — and pulled the internal rollout in by two months.
  • Designed the PromptBuilder pipeline (backend metadata + a learner's full-stack project data + LLMs) and cut a 6-week timeline down to 2.
  • Sat through 10+ learner interviews, found the real UX friction in activity design, and the redesign moved completion up 24%.
  • Owned session-level NPS for mentor-led cohorts and kept it at 8.7 on average.
  • Built a root-cause audit tracker across 1,500+ automated support tickets so the team argued about data instead of vibes.

Product Engineer

Crio.Do · Bengaluru

Nov 2022 — May 2025

Promoted twice. Mostly curriculum, autograders, and the deploy pipeline.

92% completion80+ NPS30% faster grading80% ops automated
  • Conceptualized and launched India's first Advanced SDET program — 13 modules, 92% completion, 80+ NPS.
  • Dug through behavioral data (SQL + Python) for 20+ users, found people misreading optional content, and redesigned the UI to fix it.
  • Put Kafka + Docker hands-on labs into the curriculum so the cloud stuff stopped being theoretical.
  • Wrote Python + Docker autograders for 30+ projects — grading got 30% faster and feedback became real-time.
  • Scripted away ~80% of the manual Discourse content ops across 1,500+ articles.
  • Set up Jenkins-based deploys for backend services on Cloud Run + Docker.

Co-founder & Full-stack Lead

FormulaAI · Bootstrapped

Apr 2025 — Sep 2025

An AI JEE-prep app, built from nothing with two hands and a cloud bill.

80% faster deploys−23% bounce3 eval pipelines
  • Bootstrapped the whole thing on Supabase, GCP and AWS — frontend to infra.
  • Wrote and shipped a modular AI Service (FastAPI + PostgreSQL on AWS EB) that orchestrated between the LLMs and the platform.
  • Used low-temperature, multi-model validation heuristics to keep hallucinations down across 3 evaluation pipelines.
  • Wired CI/CD with Amplify + Cloud Run and cut deploy time 80% with Docker layer caching.
  • Built the Next.js landing page; bounce rate dropped 23%.
