ENGINEERING SERVICE

Custom web platforms built to last and evolve

Full-stack web products in React, Next.js, and TypeScript — with the design systems, backend, and deep integrations that turn a first release into a durable platform.

CAPABILITIES

What we build end to end

Product engineering that pairs a modern frontend with the backend, data, and integration work most SaaS teams underestimate.

React & Next.js apps

App Router, server components, streaming, and edge rendering used where they earn their complexity.

Design systems

Token-first component libraries in Storybook that keep visual and behavioral consistency as the product grows.

Backend & APIs

Node.js, Python, and Go services behind REST, GraphQL, and tRPC APIs with observability from day one.

Data modeling

Postgres schemas, migrations, and query patterns that stay fast as usage and cardinality grow.

Auth & permissions

Multi-tenant identity, SSO, per-resource authorization, and audit trails built into the base of the app.

Payments & billing

Stripe subscriptions, metered pricing, tax handling, and receipts wired end-to-end into the product.

HOW WE ENGAGE

A path from idea to shipped product

Four phases with tight feedback loops between product, design, and engineering.

01

Product discovery

We align on the users, jobs to be done, and success metrics, and shape a scope that fits real timelines.

02

Design & architecture

Wireframes, visual design, and a technical architecture reviewed together so trade-offs surface early.

03

Build & integrate

Two-week sprints with working software in staging every cycle, CI-enforced quality, and demoable increments.

04

Launch & operate

We ship, wire monitoring and support, and keep improving with a clear post-launch cadence.

TECHNOLOGY

The web stack we build on

A mature TypeScript-first toolchain from frontend to database, with hosting patterns tuned for real workloads.

USE CASES

Where custom web is the right call

Products with real business logic, complex data, or integration depth that off-the-shelf tools cannot cover.

↗

SaaS platform builds

Multi-tenant products with auth, billing, admin, and reporting engineered as one coherent platform.

↗

Marketplaces

Two-sided marketplaces with search, listings, messaging, payouts, and trust and safety controls.

↗

Internal admin tools

Operations consoles that replace spreadsheets and no-code hacks with real workflows and permissions.

↗

Customer portals

Self-service portals for orders, invoices, contracts, and support integrated into your systems of record.

↗

Onboarding & KYC flows

Multi-step flows with verification providers, progress persistence, and support-friendly error handling.

↗

Data-heavy dashboards

Reporting surfaces that stay fast on large datasets with proper caching, pagination, and query design.

BUSINESS IMPACT

Outcomes owners actually care about

The product ships, teams can maintain it, and every release is faster than the last.

01

Faster time to market

Battle-tested scaffolding and reference architectures cut months off the first shipping release.

02

Maintainable codebase

Typed contracts, tested critical paths, and clear boundaries so the second team to touch the code moves fast too.

03

Predictable delivery

Sprints with demoable output every cycle, so scope and timelines are grounded in real progress.

04

Product that scales

Data models, background jobs, and hosting patterns chosen so growth does not force a rewrite.

FAQ

Answers on custom web engagements

Practical answers on scope, delivery, and how we work with your existing team.

How do you scope a first release?
We identify the smallest system that proves the core value, cut everything else to a backlog, and set a delivery date we can actually hold. Extras come after real usage.
Can you work alongside our in-house team?
Yes. We work in your repos, join your standups, and hand off cleanly. Many engagements start as staff augmentation and grow into full ownership of a subsystem.
Do you use React and Next.js on every project?
Usually yes because the ecosystem is deep and the team is senior in it. When the problem fits better in another stack — Remix, SvelteKit, or a Django admin, for example — we say so and use that instead.
How do you handle design?
We can bring product designers in or work off your existing design work. Either way we build a component library early so the visual language stays consistent as pages expand.
How do you handle testing and CI?
Critical paths get end-to-end tests, business logic gets unit tests, and CI runs them on every PR. We do not chase coverage numbers, we protect the flows that matter.
What happens after launch?
We stay for a defined support window and can transition into ongoing SRE or product engineering. Documentation, dashboards, and runbooks are part of the handover in every case.
