Technology we use
How we deliver web app development
Technical discovery
We map requirements, integrations, and constraints before writing a line of code.
Architecture design
We choose the rendering strategy, data layer, and hosting model that fits your scale.
Iterative development
We ship in short, reviewable increments with continuous QA and stakeholder demos.
Launch & optimization
We monitor real-world performance and tune Core Web Vitals post-launch.

Common questions
Do you build on top of an existing codebase?+
Yes. We regularly take over and modernize existing web applications, including full migrations to Next.js and React.
Can you integrate with our existing CMS or backend?+
Absolutely — we routinely integrate headless CMS platforms, ERPs, CRMs, and internal APIs into new frontends.
How do you approach performance?+
Every build is measured against Core Web Vitals targets from the first sprint, not bolted on at the end.
