Web App & SaaS Development

Custom web app & SaaS development

Custom software for the work spreadsheets and off-the-shelf tools can't handle.

What I do

When your business outgrows spreadsheets and off-the-shelf tools, a custom web app fits your exact workflow. I build SaaS products, dashboards, portals and internal tools end to end: database, API, interface and deployment.

Recent builds include a multi-company e-signature platform, a VoIP route-testing suite with live dashboards, and an eSports tournament platform with wallets and an anti-cheat approval flow.

FAQ

Web App & SaaS Development: common questions

Can you build an MVP for my startup?

Yes. We start by agreeing the smallest version that proves your idea, I build and launch it, and we add features based on what users actually do.

Who owns the code?

You do. The code lives in your GitHub repository and the hosting is in your accounts, so you're never locked in to me.

Can you work on an existing codebase?

Yes. I can add features, fix bugs, improve performance or modernise an existing React, Next.js, Node.js, PHP or Laravel application.

How do we communicate during the project?

You'll get regular progress updates and a live preview link you can click through, and you can reach me on email, WhatsApp or video calls in your time zone.

How secure will my web app be?

Every build gets HTTPS, hashed passwords, role-based access and rate limiting. The Web + App Suites add an automated vulnerability scan and a written security report, two-factor login and audit logs from Secure Business up, and field encryption, load testing and a disaster-recovery plan in Secure Enterprise. An outside VAPT test by an independent security firm is included in Secure Enterprise and available as an add-on, at cost, for the other plans.
