Start from the workflow
We map how people actually do the work today, including the spreadsheets and workarounds, and design the application around that.
Architecture sized to the business
A well-structured monolith for most products, with services split out only when scale or teams demand it. Less infrastructure means lower running costs.
Integrations as first-class features
CRMs, ERPs, payment providers and data feeds are designed in from the start, with retries, logging and alerts, so data stays consistent.
Ready for your next developer
Automated tests, clear documentation and a standard stack mean any competent team can maintain the application, including your own.

Web Application Development FAQs
What technology do you build web applications with?
Most of our web applications use React or Next.js on the front end and Node.js or Python on the back end, with PostgreSQL or MongoDB, deployed on AWS or Google Cloud. We recommend a stack based on your team, scale and integrations.
Can you work on an existing web application?
Yes. We start with a short audit of the code, infrastructure and open issues, then agree a plan for fixes and new features.
Should I choose fixed price or time and materials?
Fixed price suits a well-defined scope with a firm budget. Time and materials suits evolving products and ongoing development. Many clients start fixed price and move to a dedicated team.
How do you handle security?
We follow least-privilege access, keep secrets out of code, review dependencies, and build authentication and authorization into the design. For regulated data we plan compliance requirements into the scope.
