[ 01 ]About

The short version

I build iOS products — and I've been doing it long enough to remember when Swift was the new kid. Most of my fifteen-plus years have been spent at the early, messy, exciting stage: leading iOS at startups where you own everything from architecture to App Store review. I've shipped apps for respiratory patients, sports fans, gig workers, and online shoppers, and along the way I learned the skill I value most — turning an ambiguous product idea into something polished that people actually use.

In 2022 I went back to school — a postgraduate degree in artificial intelligence at Georgian College — because I could see where software was heading. Today I architect AI agent systems: LLM-powered agents with real tool use, retrieval pipelines that ground them in truth, and on-device intelligence with Core ML. The bet I'm making is simple: the next generation of great products will be agentic, and they'll live on the devices I've spent my career mastering.

[ 02 ]Experience

Nine roles, one through-line

From first App Store submission to agentic systems — the whole arc, 2016 to today.

  1. Client appsJan 2016 — Jun 2018Mohali, India

    Applify Tech

    Software Executive, iOS

    First professional iOS role. Learned the craft the only way that sticks — shipping client apps in Objective-C and early Swift, and earning every App Store approval the hard way.

  2. Client portfolioJul 2018 — Jul 2019Mohali, India

    smartData Enterprises

    Software Development Engineer, iOS

  7. HealthtechJun 2023 — Jun 2024

    NuvoAir

    Lead iOS Engineer

    Led iOS at a product studio — owning architecture and delivery across builds, and holding the bridge between design and engineering.

  9. Sports & gamingMar 2025 — Present

    DraftKings

    Senior Software Engineer

    Senior engineering at one of North America's biggest sports entertainment platforms — consumer scale, live-event traffic, and the polish a flagship app demands.

[ 03 ]What I build

Two crafts, one builder

Fifteen years of iOS craft, now wired into agentic systems.

iOS Engineering

Native apps with the fit and finish people expect from the platform.

  • Swift, SwiftUI & UIKit

    Fluent across the modern and classic stacks — with Objective-C for wherever the legacy lives.

  • Architecture that lasts

    MVVM, Combine, and async/await — codebases that stay fast to ship in, year after year.

  • App Store delivery

    Provisioning to phased rollout — I've shipped through every flavour of App Review since 2016.

  • UI/UX-driven development

    Design-partnership engineering: motion, haptics, and the details that make an app feel expensive.

  • Cross-functional leadership

    Agile team leadership at startup speed — aligning design, product, and engineering without ceremony.

AI Agent Systems

Agents designed around real product jobs — not demos.

  • LLM agent design

    Agents that plan, act, and recover — scoped to do one job exceptionally well.

  • Tool use & function calling

    Pipelines that let models operate real systems safely — schemas, guardrails, graceful failure.

  • Retrieval-augmented generation

    RAG that grounds agents in your actual data, with retrieval tuned for trust.

  • On-device intelligence

    Core ML and Apple Intelligence — private, instant AI that ships inside the app.

  • AWS & Python backends

    AWS ML foundations and Flask services — the server side an agent needs to stand on.
