Working on AI Agents, Quant and Backend

Résumé
  • I am currently looking for AI Engineering roles around AI agents, quant, and backend. Previously, I was Founder's Office & AI Engineer at Multibagg AI.
  • I'm in my final year of undergrad at IIT Patna. Was also the national finalist at IFF–FinTech Olympiad '24, among the top 30 out of >1 lakh candidates.
  • I love building AI agents — for finance, payments, data pipelines, news, Instagram analysis, and most workflows I can automate.
  • I've mainly worked on Ask Iris and Multibagg AI, which has answered over 500K+ user queries and helps investors daily. It's loved by users and the sharks on Shark Tank India Season 5.
  • Fun fact: got into finance pre-COVID, watching Dad invest in the stock market. Investing since 2019 — was not 18 yet, lol 😅 — generally profitable, with a few F&O losses too. Nine out of ten people lose in F&O — stay away unless you actually know what you're doing.

Runnable city foundation · cloud agent, memory, and learning in progress

Imagine Clash of Clans for your codebase: every file is a village building, and you can watch builders work on it. I'm building a cloud agent to fix issues and open PRs, with six layers of memory and a reinforcement learning loop planned to make its decisions more accurate and cost-efficient.

DevSweep

SwiftSwiftUImacOS

Native SwiftUI · Trash-only cleanup, never rm -rf

A native macOS utility that finds regeneratable developer files: node_modules, build caches, DerivedData, explains why each folder was detected, and moves only the items you approve to Trash.

RecoveryOS

Razorpay AI Buildathon · verified Test Mode recovery flow

An explainable revenue-recovery system for Razorpay merchants: AI proposes one bounded action, deterministic policy guards execution, and durable workflows follow failed payments to auditable outcomes.

Make recovery predictable, explainable, and trustworthy.

Research & markets

LLM Trading Arena

Next.jsTypeScriptRedisOpenAITailwind CSS

Frontend · Nifty 50 paper-trading arena

An experiment where LLMs paper-trade Nifty 50 stocks using market news, including each story's sentiment and importance, custom technical indicators, quantitative analysis, and portfolio strategies. The read-only dashboard lets you follow their trades, rankings, and portfolio performance, with reproducible Redis-backed replay.

Vritta AI

Next.jsTypeScriptRedisVitestBullMQPineconeAzurePostgreSQL

Ranked financial news · traceable events · Indian equities first

A financial-news platform for following topics and regions on demand. It fetches news, filings, and disclosures, ranks their importance, and connects related items to structured, traceable events with source context and materiality. Its current focus is Indian equities, helping researchers move from a headline to the evidence behind it.

LLM Trading Arena Engine

Backend · quantitative features and auditable simulation

A TypeScript paper-trading engine for LLMs on the Nifty 50, with technical features, portfolio-aware risk context, Redis state and reproducible execution rules.

From research to rigorous, reproducible execution.

Agents & automation

Room FloorPlan

PythonSwiftOpenAIOpenCVNumPyLiDARReinforcement learning

Room AI take-home · geometry owns centimetres, the LLM cannot write wall lengths

Imagine assessing a house for an insurance claim: every wall and patch of damage needs measuring. This local pipeline uses iPhone LiDAR to map the floor area and room geometry, then computer vision and LLMs to find and classify damage, producing a measured floor plan with evidence for an estimate.

Library Survey

SwiftFastAPIRedisOpenAICloudflareOpenCVYOLOLiDARReinforcement learning

Replacement-cost survey · models propose, they don't write count or money

An iPhone LiDAR app uses a live AI guide to walk a surveyor through the library's floor plan, damage, shelves, and other objects. Computer vision counts books from their spines; ISBN, barcode, and title evidence help identify editions; web searches draft local prices. After sealing, two models independently review the same evidence, and Jev suggests recapture or human review under fixed rules. An offline reinforcement-learning loop is designed to improve that routing, while a signed report estimates the whole library's replacement cost.

Instagram Creative Intelligence

Next.jsTypeScriptOpenAIFFmpegZod

Evidence-first analysis · reports, transcripts and frame sampling

A multi-agent analysis pipeline that ranks public Instagram posts, extracts video and audio evidence, and turns measurable creative patterns into an adaptable strategy report.

Go Rabbit

Next.jsTypeScriptOpenAIGitHubZod

Issue → validated patch → draft PR

An agentic contributor assistant that scopes Go issues, scans repositories, generates and validates focused patches, and prepares draft pull requests behind explicit safety gates.

Automate the boring, ship more confidently.
