Product engineer · mobile · web · ai

I don't just write code — I build products you can grow a business on.

Founders hire me when they need more than tickets closed — a senior partner who owns the build from architecture to launch, talks in plain terms, and stays accountable after go-live. Mobile, web, and AI, shipped as one product.

About

Your product is an asset. I treat it like one.

I started shipping apps because I watched too many founders burn budget on code that never reached real users. Today I help teams launch products that earn trust early — then scale without a rewrite six months later.

You work with one senior engineer who owns the whole story: mobile, web, and intelligent features designed together, not bolted on. Honest timelines, weekly visibility, and code your team actually owns.

What I do

Engagements that move the business forward

Every build ties back to a user or revenue outcome — you always know what we're making, why it matters, and what success looks like before a line is written.

How I work

From first call to shipped — and beyond

No mystery, no endless discovery decks. A clear path with visible progress at every step, so you always know where your product and your budget stand.

01

Discovery & scope

We pin down the real goal, the riskiest assumptions, and the smallest version that proves it. You get a written scope, timeline, and price — no surprises.

02

Architecture & plan

I design the system to scale from day one and break the build into milestones you can see and pay against. Decisions explained in plain terms.

03

Build & ship

Weekly visible progress and working software you can click — not status reports. We ship in slices so value reaches users early, not in one risky bang.

04

Iterate & support

After launch I stay on: real-usage feedback, fixes, and the next features — aligned with where the business is actually going.

Selected work

Products that solved real problems

Each engagement started with a business goal — reach users, save time, unlock revenue — and ended with something people rely on in production.

Why a product engineer

One senior partner beats a ticket queue

Most founders don't need a bigger team — they need one person who owns the outcome and actually cares whether the product works.

The agency route

  • Sales rep up front, junior devs behind the scenes
  • Scope padded to fill a team's hours
  • Mobile, web, and AI split across disconnected pods
  • Status decks instead of shipped features

What clients say

Trusted by founders & product leaders

Devesh doesn't just ship code — he thinks like a product partner. He turned a complex automation vision into something our team uses every day. Structured, fast, and always ahead of the brief.

Rahul Mehta
Founder · B2B automation platform

Working with Devesh felt like having a senior product engineer on the team. He owned the architecture, communicated clearly, and delivered a platform we could put in front of paying customers without hesitation.

Sarah Chen
Co-founder & CTO · AI SaaS startup

We went from Figma to App Store in ten weeks — with analytics, onboarding, and a release process we still use. He pushed back on scope that would not move retention, and he was right.

James Okonkwo
Founder · Consumer mobile app

Our dashboard was drowning in feature requests. Devesh helped us define what actually mattered for revenue, shipped it in slices, and left us with code our in-house team could extend.

Priya Nair
Product lead · Funded marketplace

Trust was non-negotiable for our copilot — citations, fallbacks, evals before launch. He treated AI like a product surface, not a demo, and our beta users noticed the difference immediately.

Michael Torres
Founder · Health-tech startup

Honest timelines, weekly working software, and no lock-in. Everything lives in our repos and cloud accounts. That alone saved us when we hired our second engineer six months later.

Questions

The things founders ask before we start

What time zone are you in, and how do we communicate?
I'm in India and work comfortably with US, UK, AU, and Middle East teams — overlapping live hours plus async updates. You get a weekly sync, a shared roadmap, and direct access to me, not a project manager relaying messages.
Do you do fixed-price projects or only retainers?
Both. One-time MVP builds are scoped and quoted as fixed-price with milestones. Ongoing work runs on the monthly retainers above. We'll pick whatever fits your stage on the first call.
Who owns the code and the accounts?
You do — fully. Everything is built in your repositories and your cloud accounts, documented so your team (or a future hire) can pick it up without me. No lock-in.
How soon can you start?
I take on a limited number of projects at once to keep quality high. Right now I'm open for one new project — book a call and I'll give you the honest earliest start date.
Can you handle design too, or just engineering?
I handle product and UX decisions and ship polished, usable interfaces. For heavy brand or visual design I bring in a trusted designer — and manage that for you so it stays one coherent product.
Will you sign an NDA?
Yes, happily. Send yours over or I can provide a simple mutual one before we get into specifics.
