Architect & Developer
Systems That Work

Over a decade of experience in building end-to-end software solutions. I believe in building it right from the foundation, working with honest people, and creating systems designed to grow.

Building Right, From the Foundation

"With 13 years in the development world—as an employee, tech lead, and business owner—I've learned that good technology is first and foremost one that serves the product and the people behind it. I don't just write code; I design systems meant to grow, perform, and remain maintainable over time."

I don't only build from scratch; my expertise is entering existing systems (Legacy), deciphering complex logic, and bringing order to the mess. I believe clean architecture isn't a luxury but a necessity to prevent technical debt, and I know how to bring that standard even to projects already in motion.

Recharging Batteries

When the screens go off, I swap the keyboard for a guitar, train, or enjoy a good stand-up show. For me, this balance isn't just leisure—it's essential for arriving at every project with fresh thinking, focus, and a creative perspective that allows me to crack complex technical challenges.

The Standard

"Quality code that gives real value to the business."

Guiding Principles

  • Clean & Maintainable Code
  • Simplicity instead of Complexity
  • Transparency & Working at Eye Level

Selected Projects

PythonOpenAI WhisperFFmpegAutomation

Automation & Sound Processing (Python)

Organizing and processing messy audio files using AI.

The Challenge

Difficulty managing and sorting a pile of voice files in a chronological and readable manner.

The Result

Developed an automation tool integrating OpenAI Whisper for textual processing and automatic file organization based on content and time.

PHPJavaScriptWordPress APIMySQL

Price Optimization for eCommerce

Custom solution for discount management and bot scanning in WordPress.

The Challenge

SEO and data sync problem: Search engine bots didn't identify sale prices, which hurt the display of correct prices in search results.

The Result

Building a dedicated plugin for smart discount management (at the product or category level) with custom data injection for bots. The solution ensured correct price display in search and simplified promotion management on the site.

PHPAPI DesignCustom EngineMySQL

Warranty & Registration Engine (Custom PHP)

Replacing a collapsing legacy infrastructure with a dedicated API-based system.

The Challenge

A slow system with critical bugs that hurt customer service and caused unrest for the business owner.

The Result

Built a fast Core from scratch in PHP. The system enables full automation of warranty certificates, rapid customer management, and performance that significantly improved the user experience.

ReactNode.jsPostgreSQLArchitecture

Product Development (Stealth Startup)

Building a technological MVP from the characterization stage to launch.

The Challenge

Need for a stable yet flexible product to allow rapid changes during early development stages.

The Result

A clean Full-stack architecture that enables fast scaling, while maintaining smooth UI/UX and high performance.

AngularTypeScriptEnterprise CMS

CMS Management System (Modern Angular)

Developing a complex content management system for a broad service platform.

The Challenge

Need for a strong, fast, and secure Admin interface for full control over registration processes and value-added services.

The Result

Built using Modern Angular with a modern architecture. Enables intuitive management of complex business logic with high stability.

FlutterMobile DevServices UI

Mobile Components Development (Flutter)

Leading the development of services in a cross-platform app.

The Challenge

Implementing end-to-end processes for users, such as parking service registration and Gift Card management within an existing app.

The Result

Developing complex features in Flutter with an emphasis on a smooth user experience and high performance on mobile devices.

How Can I Help?

Planning & Architecture

Engineering planning from scratch or restructuring existing systems. I help you choose the exact stack and build a scalable foundation that lasts for years, and not just until the next demo.

End-to-End Full-stack Development

Building modern web apps (React/Node.js/Vue) with an emphasis on clean and maintainable code. My expertise is taking a business requirement and turning it into a working, secure, and fast product.

Mentoring Entrepreneurs & MVP

Turning your vision into a working product (Proof of Concept) in minimum time and maximum quality. I build a strong technological foundation that allows rapid growth without unnecessary technical debt.

Consulting, Optimization & Legacy Code

Specializing in entering existing systems, locating bottlenecks, and solving complex bugs. I help you improve performance and turn 'spaghetti code' into a modular and organized system.
