Software Engineer at Sarcon, Malda, India

Kuntal Sarkar

I build AI agents that set up and run large events, plus the platform under them. Teams at Amazon, Microsoft and IBM use it.

4+ years shipping Laravel, React and Python in production: agentic workflows on the Claude API, face-recognition check-in, and pages that load fast with 10,000 people on them.

Before and after

Three things I made faster at Sarcon. Each grey bar is how long it used to take; the gold bar is how long it takes now.

  1. Badge design

    AI design system that generates event badges from a brief

  2. Attendee check-in

    Face recognition that works with masks, glasses and low light

    < 5 s18× faster
  3. Page load

    Redis caching and query work for events with 10,000+ attendees

What I build at Sarcon

Sarcon makes software for in-person, hybrid and virtual events: registration, apps, on-site check-in. I've been there since 2021, starting as an intern.

Agentic AI operations platform

An agent that runs event operations through conversation. Organisers ask in plain language, and it updates speakers, adds conditional registration fields and edits badges. Setup that used to take weeks now takes minutes.

  • 117+ tools, picked per request by vector-based routing
  • Memory across the conversation, plus multi-step reasoning
  • Guardrails: domain-aware tools refuse destructive actions

Face recognition check-in

Touchless entry in under a second per face. It also tracks zones and sessions, counts meals and giveaways, and catches ticket fraud.

Python, computer vision

Virtual event ecosystem

3D booths, networking and conference tools, so remote attendees can walk the floor and talk to exhibitors.

React, Three.js, WebRTC

Payments and pricing

Integrations with several payment providers, a pricing engine and coupons for ticketing at enterprise scale.

Laravel, PostgreSQL

About me

I have an MCA from Pondicherry University (2022) and a B.Sc. in Computer Science from Malda College (2020). My final-year project was a face-recognition attendance system, and I've been building things that see, reason and scale ever since.

I speak Bengali, English and Hindi.
