Full-Stack Developer | Backend Architect & Data Systems Specialist
I build scalable, high-performance software systems where speed and data integrity are non-negotiable.

With deep expertise in Modern Web Development, Backend Architecture, and Data Engineering, I help businesses bridge the gap between complex logic and seamless user experiences. Whether you need a robust Spring Boot backend, a real-time TypeScript SDK, or a Star Schema data warehouse, I focus on building systems that are modular, maintainable, and built to scale.

What I Bring to Your Project:

Robust Web & Backend Engineering: I specialize in building secure, high-concurrency backends using Java Spring Boot, Node.js, and RESTful APIs. I focus on clean architecture that ensures your application stays fast as your user base grows.

Scalable Infrastructure & SDKs: I have extensive experience architecting custom, modular TypeScript SDKs. I specialize in standardizing complex logic—such as session management, real-time socket connections, and automated timer systems—to ensure your internal teams can build and deploy faster.

Advanced Data Warehousing & BI: I don’t just store data; I make it useful. I design comprehensive Star Schema data warehouses and ETL pipelines (Python/SQL) to consolidate fragmented metrics into a "User 360" view, giving you total visibility into your business performance.

Performance & Algorithm Optimization: I excel at solving "heavy lift" problems. By combining the flexibility of Python/Selenium with the raw speed of C++, I build high-performance automation and algorithmic tools that most web-only developers can't replicate.

Technical Expertise:

Languages: TypeScript, JavaScript (ES6+), Java, Python, SQL, C++.

Backend & Web: Node.js, Spring Boot, Three.js, React, Express.

Data & Infrastructure: PostgreSQL, MySQL (Star Schema, Fact/Dim Tables), ETL Pipelines, SDK Architecture.

Specialized Tools: Redis (Caching), Selenium (Automation), Git, REST/Websockets.

I am a university-trained developer who approaches every project with the mindset of a software architect. If you need someone who can handle the full lifecycle of a project—from database schema design to the final front-end deployment—let’s connect.
