Why me

Work directly with the engineer, not a middleman

The person you talk to is the person who writes the code — and owns the standard.

PRODUCTION-PROVEN

Standards from systems I operate myself

Dexova — an ERP with HRIS/payroll, POS, and inventory — is built and run by me in production. Your project gets the same standard.

BACKEND-FIRST

A strong backend foundation

Go, Java/Spring Boot, Laravel. Secure, measurable, documented APIs — not just a UI that looks good in a demo.

PERFORMANCE + SEO

Fast & discoverable from day one

Core Web Vitals, structured data, and sitemaps built in from the start — not patched on after launch.

NO MIDDLEMAN

Direct communication, transparent progress

Discussion, estimates, and regular updates come straight from me. You see progress, not work behind a curtain.

Transparent from kickoff to release

Three simple stages — you always know where the project stands.

01

Scope & estimate

We discuss goals, needs, and constraints. I help define a clear scope plus a time/cost estimate — free, no commitment.

02

Design & build

I work in stages with regular updates. You see progress as it happens, not work behind a curtain.

03

Release & support

Deploy to production, hand over documentation, plus a support window for fixes and adjustments.

Frequently asked questions

How much does a website or application cost?

It depends on scope: pages, features, and integrations. After a free discovery chat, I send a clear time and cost estimate so you can decide with confidence.

How long does it take?

A simple landing page is usually 1–2 weeks. Web apps, APIs, and online stores take longer depending on feature complexity. You get a firm estimate once scope is clear.

Do you work remotely?

Yes — all projects are delivered remotely, with communication over WhatsApp or video calls and regular progress updates.

How does payment work?

In stages, tied to milestones agreed upfront — never full payment in advance.

Do I own the source code?

Yes. After handover, the source code and deployment access are fully yours.

Free discussion & estimate, no commitment. I usually reply within 24 hours.
