Service — Product Engineering

Full-stack product development

The whole stack, one team — web, mobile, backend, database, and DevOps. From system design to production deployment, on engineering proven at 1M+ device scale.

The Problem

Shipping a product takes the whole stack

What's Included

One team, from system design to deploy

We take products from architecture to production — the same engineering that carried Battery Smart from seed to a $340M valuation.

How We Work

How we take products to production

  1. Architecture & scope We design the system and lock a concrete scope for the first release before building.
  2. Iterative build We ship in working increments you can review, not a big-bang reveal at the end.
  3. Hardening Load, edge cases, monitoring, and CI/CD — the work that separates a demo from production.
  4. Launch & support We deploy, watch it under real traffic, and stay on for the stabilisation window.

Fixed-scope packages with prices tailored to your custom requirements. We scope to a defined outcome and quote a fixed price before we start — no open-ended hourly billing. Larger or multi-phase builds are milestone-based.

Proof

Proven at scale, twice over

At Battery Smart, our founder led the engineering from seed to a $340M valuation — a six-application ecosystem and telemetry infrastructure serving 1M+ IoT devices without buckling under concurrent load.

For the Harvard Club of Silicon Valley, we built a full member portal — events, registrations, and tiered membership with Stripe billing — on React, Node.js, and PostgreSQL.

FAQ

Full-stack development FAQs

What's your stack?

React and modern JS on the front end, Node.js and Python on the backend, PostgreSQL and other databases as the data model demands, and standard cloud infra with CI/CD. We pick per project rather than forcing one stack onto every problem.

Can you take over an existing codebase?

Yes. We can pick up an in-flight product, audit it, and either extend it or plan a migration — we'll be straight with you about which makes more sense.

Do you build mobile apps too?

Yes — customer-facing and operational mobile apps. At Battery Smart the suite included driver, partner, and operations apps alongside the web portals.

Will the same team handle deployment and scaling?

Yes. DevOps isn't a separate handoff — we own architecture through deployment and the stabilisation window after launch, which is exactly where multi-vendor setups tend to break.

How do you scope and price a build?

We design the architecture and lock a concrete scope for the first release, then quote a fixed price for it. Larger products run in milestone-based phases.
