Web apps built to grow with your business
One accountable team handling architecture, design, engineering, infrastructure, and long-term maintenance.
Architecture & API Design
Component structure, state model, and API contracts designed for the next two years of growth, not just the next sprint.
React + TypeScript Frontend
Production-grade UI with strict typing, accessible components, and performance budgets enforced in CI.
Node.js Backend
Same language frontend to backend. Modular services, clear domain boundaries, easy to extend or split later.
Database & Data Modeling
PostgreSQL by default. Schemas designed to scale, migrations versioned, no surprises at 100k rows or 100M.
Testing & Code Quality
Unit, integration, and end-to-end tests in CI. Code review before every merge. The kind of codebase you can hand to a new engineer on day one.
Performance & SEO
Server-rendered where it counts, lazy-loaded everywhere else. Core Web Vitals in the green, structured data shipped from day one.
A transparent path from first call to production
Four phases. Fixed scope before code. Working software every two weeks. No black-box delivery.
- 01 1–2 weeks
Discovery
We map your goals, users, technical constraints, and integration points. Outcome: a fixed-cost statement of work and a working architecture sketch.
- 02 Signed before kickoff
Statement of Work
Milestones, deliverables, timelines, and tech decisions, agreed up front. Whether fixed scope or dedicated team, you know exactly how we work together.
- 03 2-week sprints
Build
Working software at the end of every sprint. Demos, feedback, fast adaptation. Reviewed, tested code, frequent deploys.
- 04 Ongoing
Launch & Scale
Production deploy, monitoring, smooth handover. We stay on for the maintenance and feature work that keep the product evolving as it scales.
The kinds of teams we build for
Web app development is the right call when you need senior depth, long-term thinking, and a partner who'll stay on past launch.
Companies rebuilding legacy products
Your existing app is fragile, slow, or locked into ancient tech. We rebuild on a modern stack you can hire for, without losing the features your users rely on.
Funded startups past MVP
You shipped the MVP, found traction, and now need a production-grade rebuild that scales past 10k users. We re-architect for the next phase.
Internal tools and admin platforms
B2B dashboards, ops tools, CRM extensions. Web apps where reliability and clean UX matter more than flashy marketing pages.
SaaS products needing senior depth
Multi-tenant architecture, role-based access, billing, integrations. We've built every layer of the modern SaaS stack.
A modern, boring, battle-tested stack
We pick tools that solve your problem and stay maintainable for years. No frameworks-of-the-month.
React + TypeScript
Strict typing across the codebase. Catch errors at compile time, not in production.
Node.js
Non-blocking I/O, massive ecosystem. Same language frontend to backend means faster team velocity.
Astro / Next.js
When SEO and Core Web Vitals matter. Server-rendered, hydrated only where needed.
PostgreSQL + Prisma
Type-safe database access. Migrations that survive years of schema changes.
AWS Serverless
Lambda, API Gateway, RDS. Scale to millions with no DevOps team.
GitHub Actions + Sentry
CI/CD pipelines that run tests and ship to prod on merge. Error tracking from day one.

What teams ask us about web app development
Short, honest answers. If yours isn't here, book a call and we'll answer it directly.
What does a typical web app project cost?
// Answer
Fixed-scope web app projects come with a defined total upfront, depending on feature surface, integrations, and design depth. Dedicated team engagements run on a clear monthly retainer based on the people you need. Book a 30-minute call and we'll give you a concrete range based on your scope.
How long does it take to build a production web app?
// Answer
MVPs ship in 8 to 16 weeks. Full production apps with auth, billing, multi-tenant data, and integrations typically take 4 to 6 months. We lock the exact timeline in discovery, before any code is written.
Can you take over an existing codebase?
// Answer
Yes. We start with a 1-week code audit to understand the existing architecture, technical debt, and risks. From there we either rebuild incrementally (recommended for most cases) or full-rebuild with a parallel cutover plan.
Do you do design too, or just engineering?
// Answer
Both. Product design (UX research, wireframes, high-fidelity UI) is part of every web app engagement unless you have an in-house design team. One contract, one accountable team, no handoff friction between design and engineering.
How do you handle scaling and performance?
// Answer
From day one. We set performance budgets in CI, server-render where SEO matters, and design APIs to scale horizontally. AWS serverless means you don't pay for idle capacity, and infrastructure scales automatically.
What about ongoing maintenance after launch?
// Answer
We don't disappear at launch. Most clients stay on a monthly retainer for ongoing feature work, security updates, and infrastructure monitoring. Many of our launch clients have been with us for years.
Three ways to work together
Fixed-scope project, ongoing product team, or senior engineers inside your own team. Pick the model that fits your stage.
Fixed-Scope Project
Best for clear scope and a fixed budget.
- Defined scope and milestones
- Fixed timeline and budget
- Signed SOW before kickoff
- Launch and handover included
- 30 days of post-launch support
Dedicated Team
Best for products that need an ongoing partner.
- A senior team that's truly yours
- Sprints, roadmaps, and demos
- Full visibility and reporting
- Flexible scope as you grow
- Design, build, DevOps, and support
Staff Augmentation
Best for adding senior engineers to your team.
- Senior React, Node.js engineers
- Embedded in your workflow
- Scale up or down on a sprint's notice
- Your process, your tools
- No long-term lock-in
What else we do
One team, one contract, full product journey.
