01About

Engineering that survives production.

I care about the unglamorous parts that make software actually work under real traffic — cost, correctness, and reliability at the edges.

I'm a full-stack engineer who lives at the intersection of real-time systems and applied AI. As the sole engineer on a production Shopify AI Shopping Assistant, I've shipped provider-agnostic LLM gateways, bot-to-human handoff over WebSockets, and RAG pipelines that cut cost while raising reliability.

I'm most interested in the unglamorous parts that make software actually work in production — cost accounting down to the microdollar, atomic claims that survive race conditions, and caches that shave milliseconds off every message. I care about systems that are fast, observable, and cheap to run at scale.

Currently pursuing my B.Tech in Computer Science at IIIT Raichur while interning at Setubridge Technolabs. I've solved 200+ DSA problems and I'm always chasing the next hard systems problem.

What I care about

Agentic AI ArchitectureLLM Systems DesignCompetitive Programming
01

Systems thinking

I design for the whole lifecycle — state machines, race conditions, retries and fallbacks — not just the happy path.

02

Cost & performance obsession

Microdollar-precision cost accounting, dual-layer caching, and token budgets that keep AI features cheap at scale.

03

Reliability under real traffic

Atomic claims, presence dedupe, and reconnect catchup so real merchants never lose a message.

04

End-to-end ownership

From a Chrome MV3 recorder to an FFmpeg compositor — I ship the whole pipeline, sole-engineer when needed.

02Capabilities

A full-stack toolkit, tuned for production.

From provider-agnostic LLM gateways to real-time WebSocket systems — the stack I reach for, and how deep it runs.

Shipping production systems, not prototypes.

Where the résumé bullets became real traffic. A hands-on record of building, owning, and running software that merchants actually depend on.

  1. Full-Stack Developer Intern (MERN + AI/LLM)

    Setubridge TechnolabsAhmedabad, India
    Dec 2025 — PresentNow

    Sole engineer on a production multi-tenant Shopify AI SaaS, and end-to-end builder of an internal billing platform and an AI marketing-video pipeline.

    Key impact

    Shipped a 3-service production Shopify app — Remix backend, a JWT-authenticated Socket.IO gateway, and a React agent dashboard — serving merchants on DigitalOcean with per-shop row-level isolation across 26 Prisma models and 66 REST routes.

    Cut LLM cost per conversation ~55% by replacing a monolithic prompt with a 7-state intent engine that loads tier-based prompt modules on demand, with cosine-scored embedding classification and an LRU-cached GPT-4o-mini fallback.

    Built end-to-end bot-to-human handoff over WebSockets with atomic SQL-level conversation claims (no double-claim races), shared inbox, multi-tab presence dedupe, and reconnect catchup for messages missed during disconnect windows.

    Designed a provider-agnostic LLM gateway over Anthropic Claude and an OpenAI-compatible bus (OpenAI, Groq, Together, Gemini) with unified SSE streaming, tool-schema normalization, and microdollar-precision cost accounting.

    Built an internal billing platform (OpsPanel) and an AI demo-video generator from a Chrome MV3 recorder through a GPT-4o scene planner to a Python/FFmpeg compositor.
