Application & Web Development

Small, senior teams that design, build, and maintain web applications, customer portals, and internal tools. We work in short cycles, keep the codebase clean enough to hand back, and care about the operational cost of what we ship.

Capabilities

What's covered

The building blocks we bring. Most engagements use a subset, scoped to what you actually need.

Product discovery

A short, structured phase to turn an idea into a prioritized backlog, clickable prototype, and delivery estimate.

Web application development

React, Next.js, TypeScript, and Node on the front; Python or .NET services behind. Boring, well-supported choices.

Customer & partner portals

Authenticated self-service portals integrated with your CRM, billing, and support systems.

Internal tools & automation

Replace the fragile spreadsheet and the manual process with a maintained internal application.

API & integration

REST and event-driven integrations between SaaS platforms, with monitoring and clear failure handling.

Support & iteration

A managed support retainer for bug fixes, dependency updates, and a steady stream of small improvements.

How it runs

A typical engagement

  1. 01

    Discover

    Two to three weeks: goals, users, constraints, prototype, and an estimate you can take to a budget holder.

  2. 02

    Build in cycles

    Two-week iterations with a demo at the end of each. You can change direction at every boundary.

  3. 03

    Harden & launch

    Accessibility and security review, load testing, runbooks, and a supported go-live.

  4. 04

    Iterate or hand over

    Continue on a support retainer, or a clean handover with documentation and a walkthrough for your team.

Deliverables

What lands on your side

  • Clickable prototype and prioritized backlog
  • Source in your repositories with CI/CD configured
  • Automated test suite and accessibility report
  • Deployment runbook and architecture overview
Questions

Common questions

Discovery is fixed price. Build is usually time and materials against a capped estimate, because scope always moves once real users see it.
