Custom Web Application Development

If you are building a product rather than a brochure site, you need someone who can own the whole thing: the interface, the API, the database and the deployment. I build custom web applications and SaaS platforms end to end, so you work with one developer instead of coordinating several.

Past work includes a WhatsApp automation SaaS with a visual flow builder, a link-in-bio and analytics platform, and a multilingual logistics booking system. The stack changes with the problem, but the approach stays the same: keep it simple, keep it fast, and make it easy to extend.

FAQ

Frequently asked questions

Common questions about web application development.

A focused first version usually takes 4 to 12 weeks, depending on how many features it has and how many third-party systems it connects to. After reviewing your brief I give you a timeline broken into milestones.

Yes, and it is usually the better route. We agree the smallest version that proves the idea, ship it, and then add features based on how people actually use it. I structure the code so later features do not mean a rewrite.

Most projects use React or Next.js on the frontend with Node.js (Express or NestJS) or Laravel on the backend, and PostgreSQL or MySQL for data. I pick the stack from your requirements, not the other way round.

Yes. I start with a short review of the code and infrastructure, tell you plainly what is in good shape and what is not, and then propose fixes or new features.
