Product
engineering, built to last.

Web, mobile, and commerce surfaces, on a shared platform your team can keep building on for the next five years. We ship features. We also ship the design system, the CI, the observability, and the muscle memory for the team to keep going.

01 · WHY PRODUCT ENGINEERING

Built to last is a design choice

The patterns we lean on across web, mobile, and commerce — and why they keep teams shipping eighteen months in.

01

Most builds outlive the team that built them

If the platform underneath is brittle, every roadmap quarter pays a tax. We build with the next two years of decisions in mind, not just the next launch.

02

Velocity comes from the floor, not the ceiling

Speed is a function of design system maturity, CI hygiene, and observability — not heroics. We invest in the floor so feature work feels light.

03

Web, mobile, commerce shouldn't be three companies

One shared spine — design tokens, auth, analytics, flags — across surfaces. No 'mobile says one thing, web says another' incidents at month nine.

02 · WHO IT'S FOR

What we ship, by the person on the hook for delivery

persona

VP Engineering

Pain
Three squads, three stacks, three definitions of 'done.' We need a shared platform without a year-long migration.
What we ship
Monorepo, design system, shared platform layer (auth, observability, flags), and a path-to-green that respects what's already shipped.
persona

Head of Product

Pain
Marketing, web app, and mobile feel like different products. We can't ship cross-surface features.
What we ship
Cross-surface flow primitives, a feature-flag layer wired to experiments, and a feature factory that moves at the same pace on web + mobile.
persona

Design Director

Pain
Figma is pristine. The codebase ate the design system three sprints ago.
What we ship
Tokens-as-source-of-truth, primitive parity across web + mobile, and a Figma↔code pipeline that doesn't drift over a quarter.
persona

Commerce Lead

Pain
Storefront is fast. Checkout is slow. Catalog updates take a week. The platform fights us.
What we ship
Headless storefront with composable checkout, search wired to a real index, and a back-of-house console your merch team actually uses.
03 · WHAT WE BUILD

Six engineering tracks. One delivery rhythm.

We compose these into the surface area you actually need — and we build the shared platform once, so squads aren't fighting it later.

Web App Engineering

Next.js / React with real performance budgets and a design system you can extend.

  • SSR / RSC where it matters
  • Bundle budget enforced in CI
  • Per-route web-vitals dashboard

Mobile (iOS + Android)

React Native first, native modules where they earn it.

  • Expo + RN for velocity
  • Native iOS / Android for hot paths
  • OTA updates + crash budgets

Headless Commerce

Storefront, search, checkout, and back-of-house — composable, not bundled.

  • Shopify / Commerce Cloud / custom
  • Search via Algolia / Meili
  • Composable checkout flows

Design System

Tokens, primitives, and patterns — shared across web and mobile, owned by the team.

  • Figma-as-source tokens
  • Primitive parity web ↔ RN
  • Visual regression in CI

API & Data Layer

Typed end-to-end, observable end-to-end. Boring, durable, fast.

  • GraphQL / tRPC / REST as fits
  • Postgres + Redis defaults
  • Per-endpoint SLOs

Platform & DX

The floor velocity rests on: monorepo, CI, preview envs, observability.

  • Per-PR preview deploys
  • OTel tracing across surfaces
  • Feature flags wired to experiments
04 · REFERENCE PLATFORM

One spine. Many surfaces.

Surfaces on the left, the shared platform in the middle, API + data on the right, deploy targets on the far right. CI binds it all together.

Lane 01 · Surfaces

Marketing, web app, mobile, commerce, internal console — typed, shared-styled, observable.

Lane 02 · Platform

Design system, auth, analytics, flags. Built once. Used by every squad. Versioned independently.

Lane 03 · API & Data

Gateway, services, Postgres + Redis, async. Boring choices that survive migrations.

Lane 04 · Deploy & CI

Per-PR preview envs, edge + CDN, native stores, and CI gates that actually catch regressions.

05 · ENGAGEMENT

From RFC to feature factory

Most clients ship the first surface in 8–10 weeks and have a multi-surface delivery rhythm by week 18.

01
Wk 1–3

Frame & foundations

We map the product, the surfaces, and the team. Set up the monorepo, the CI, the design system seed, and the platform shape.

▸Monorepo + CI live
▸Design tokens v0

Wk 4–10 · ACTIVE EXAMPLE

Core build

First production-quality surface ships behind a flag. Other surfaces start in parallel against the same shared platform. Performance budgets in place.

Deliverables
▸Surface 1 in prod
▸Per-route budgets
▸Preview envs per PR

Wk 11–18

Surface expansion

Mobile, commerce, console — whichever is in scope — built against the same spine. A11y, i18n, perf, and observability baked in, not bolted.

Deliverables
▸Multi-surface launch
▸OTel + dashboards
▸Visual regression in CI

Handover & rhythm

Your team owns the platform with a working delivery rhythm. We stay on a lighter retainer for capability expansion.

Deliverables
▸Runbooks + on-call
▸Feature factory rhythm
▸Quarterly platform review
06 · THE STACK

Boring on purpose

We default to the durable, well-understood piece. The cutting edge comes in only where it changes the user's experience.

08 · FAQ

Asked on the discovery call

No. We pair with your team and our explicit goal is to make them stronger by the time we leave. Most engagements end with us as a smaller retainer doing platform work, while your team owns the feature factory.

Both. The hardest engagements are mid-flight migrations, and that's where we earn our keep. We define a path-to-green that respects what's already shipped and lets squads keep delivering during the migration.

Default to React Native for velocity, drop into Swift / Kotlin for hot paths or platform-specific UX. We don't pick a mobile religion; we pick the right surface per feature.

Per-route web-vitals budgets enforced in CI, real-user monitoring in production, and quarterly perf reviews. If a feature blows the budget, the PR doesn't merge — and we have a working playbook for the team to debug it.

WCAG 2.2 AA is table stakes. Visual regression + automated a11y in CI, manual audits at launch, and component primitives that bake the right semantics in by default.

A multi-surface build with platform foundations is typically ₹1–3.5Cr over 16–24 weeks depending on surface area. Single-surface refreshes start at ₹40L.
