Need a working prototype or automated system?
Let's build it. Fast.
I help businesses and individuals translate concepts into functional code. From data automation to custom web tools, get direct developer collaboration without the agency overhead.
What We Can Build Together
Premium direct development for rapid delivery of clean, highly optimized technical solutions.
Rapid Prototyping & PoCs
Turn raw business ideas or flowcharts into working code prototypes. Ideal for validating feasibility, pitches, or test-driving complex integrations.
Web Applications
Custom administrative panels, client dashboards, and responsive, lightning-fast static and dynamic portals configured for maximum usability.
Workflow Automation
Eliminate repetitive data-entry and task management. Deploy cron jobs, custom scrapers, background daemons, and system synchronization scripts.
Data & API Integration
Seamlessly bridge formats. XML, JSON, CSV, and Excel. Connect RESTful interfaces.
Specialized Health Tech
DICOM headers configuration, medical file translation, HL7 integrations, PACS routing, and automation systems tailored for healthcare networks.
CI/CD automatication
Create efficient pipeline to build, unit-test, deploy, and update database for your application automatically.
Skip the middleman. Work directly with the builder.
Have an idea for a website, mobile app, automation tool, or business system, but don't know where to start? I can help turn your concept into a working prototype that you can test, demonstrate to stakeholders, or use as the foundation for a larger project.
I work independently and communicate directly with clients, enabling faster decision-making, fewer misunderstandings, and quicker delivery.
You receive a working prototype together with the complete source code, allowing you to continue development internally, hand it over to another team, or continue working with me.
Senior full-stack engineer
Over 25 years of software development experience across web applications, automation systems, healthcare integrations, and custom business software.
Direct communication
No account handlers. You talk directly with me, aligning technical feasibility instantly.
Niche domain expertise
Experienced with DICOM, HL7, healthcare interoperability, REST APIs, and custom socket integrations.
How It Works
From idea to working prototype, step by step.
Idea Discussion
We discuss your idea, goals, and requirements. I provide technical insights and feasibility assessment.
Proposal & Planning
I create a clear proposal with tech stack, deliverables, and timeline. You review and approve.
Development
I build your prototype focusing on core functionality. Regular updates keep you informed.
Review & Iteration
You test the prototype and provide feedback. We iterate until you're satisfied.
Handover
I deliver the complete prototype with documentation and explain how it works.
What You Will Receive.
Working Software
A functional prototype demonstrating the core business workflow and technical feasibility.
Complete Source Code
Full ownership of the project source code with no vendor lock-in.
Technical Documentation
Setup instructions, architecture overview, and maintenance notes.
Knowledge Transfer
Walkthrough session explaining how the system works and how to extend it.
Warranty Period
30 days of bug-fix support after delivery.
Common questions about my service.
What is a “Working Prototype” exactly?
It's a fully functional version of your idea that demonstrates the core value proposition. It may includes either a website, desktop application, android application, tools, scripts, or docker image.
What type of projects are the best fit?
The service is ideal for prototypes, proof-of-concepts, business automation tools, custom integrations, internal systems and focused software projects with clearly defined goals.
How much do you charge for the project?
We need to have discussion of the project first. Then I can provide the quotation.
How long do you need to implement the project?
It depends on the complexity of the project. But I will provide the estimated time to complete the project after the discussion of the project. Most projects since the initial discussion, development, until the final delivery can be completed within 4 weeks or less than 3 months.
Can you provide source code of the prototype?
Yes, I will provide the complete source code of the prototype. You own the code and you can use it as you wish.
Do you provide any warranty or guarantee?
Yes, I can provide warranty for the prototype for 30 days after the delivery. during this period, I can fix any issues or bugs found in the prototype.
Can you provide user manual or documentation?
Yes, for simple system that I built for you, the code is self-explanatory. But for complex systems, I will provide the user manual and documentation.
What tech stack do you use?
For an online website, I normally use PHP + MySQL for backend and for frontend I use HTML + CSS + vanilla JS (no frameworks and no external libraries).
For a local utility or automation tool that have no GUI, I normally use Python.
For a local sandboxed GUI application, I normally use Docker + HTML + CSS + vanilla JS and run it in local machine to support MS Windows, macOS, and Linux variants.
Do I need to pay you annually for a website?
No. You only pay me once for the creating the website. You pay the domain name and hosting server fee directly to the provider.
Can you make native GUI application cross platforms between MS Windows, macOS and Linux?
Yes, I can use Python + QtPy (Qt for Python) or Qt + PySide6 (Qt for Python).
I have an existing web/application/tool, do you provide maintenance/upgrade/fix bugs service?
Yes and No. It is depending on the existing web/application, its tech stack and its complexity. We need to discuss first.
