About Dionis Markov
Building at the Intersection of AI, Cloud & Web3
Founder and lead developer at ValtheraLabs. I build AI-powered platforms, cloud infrastructure, blockchain systems, and open-source developer tools — shipping production software across the full stack.
About Me
Full-Stack Engineer & Open Source Builder
I am a 30-year-old full-stack software engineer based in Croatia. I also go by Trinexxx online. My work spans the entire development stack — from AI inference engines and microservices backends to modern web frontends and blockchain smart contracts.
As the founder of ValtheraLabs, I lead the development of an ecosystem of AI-powered applications, SaaS platforms, and developer tools. Every project is built in public, with an emphasis on clean architecture, practical engineering, and real-world utility.
This portfolio is a living showcase of that work — a window into active projects, technical explorations, and tools I ship. All code is open source and available on GitHub.
What I Do
Full-Stack Engineering
AI & Agents
LLM inference pipelines, agent orchestration with MCP, embeddings, and RAG systems for production AI applications.
Cloud Infrastructure
Scalable microservices with FastAPI, Docker Swarm, PostgreSQL, and bare-metal deployment for cost-effective hosting.
Web Development
Modern frontends with Next.js, React, TypeScript, and Tailwind CSS. Performance-optimized, accessible, and responsive.
Blockchain & Web3
Solidity smart contracts, upgradeable proxy patterns, and decentralized infrastructure for Web3 platforms.
Developer Tools
Open-source starters, Docker images, CI/CD templates, and automation tools that accelerate development workflows.
Open Source
All projects built in public on GitHub. Transparent development, collaborative patterns, and community-driven iteration.
