About this gig

Turn your product idea into a working web application you can test, demo, and build on.


I am a senior full-stack and backend developer with 13+ years of experience building SaaS platforms, APIs, distributed systems, and AI-assisted delivery pipelines. I combine hands-on architecture and engineering with supervised coding agents to move faster while keeping technical judgment, review, and accountability human-led.


Every project starts with a defined scope, core user flow, acceptance criteria, and delivery milestones.


Depending on your package, your build may include:

Responsive web interface

Authentication and user roles

Database design and APIs

File uploads or third-party integrations

Deployment and technical documentation

Source code with clear ownership


The Basic package is designed for one focused prototype flow. Standard and Premium cover functional MVPs and larger product phases.


Please message me before ordering if your project includes payments, complex AI behavior, regulated data, real-time systems, multiple user roles, or more than one external integration. I will help you choose the smallest sensible first phase and confirm what fits the package.
