Über mich

I am a highly skilled Senior Software Engineer with over 12 years of experience in software development.
I specialize in building complex systems from scratch and designing clear and flexible architectures using modern tech stacks. I prefer TypeScript, and frameworks like Vue, React, and Angular for the front-end. On the back-end, I adhere to SOLID principles, clean architecture, and occasionally microservices.

I maintain high standards for code quality, utilizing modern OOP or functional programming techniques.
I am always eager to expand my experience and adopt new programming languages or paradigms.

Key Expertise:
Front-end: JavaScript, TypeScript, Vue.js, Angular, React
Back-end: Node.js, Express, NestJS, Scala, Play, PHP, Symfony, Laravel
Databases: PostgreSQL, MySQL, DynamoDB, MongoDB
DevOps: CI/CD, AWS Cloud, Bash, Docker
Leadership: Extensive experience in leading dev teams both in-office (up to 5) and remotely (up to 10), with a preference for remote work.
AI integrations: chatbots, vector databases, OpenAI APIs, self-hosted LLMs, fine-tuning.

I excel in strategic technical leadership roles with hands-on coding, including positions such as Tech Lead, Lead Engineer, and Staff Engineer.
I can act as the Head of Engineering or CTO in a startup, managing a team as the company grows while staying deeply involved in technology.
I successfully lead teams as a tech manager, balancing approximately 70% hands-on coding with leadership duties, in roles such as Team Lead and Engineering Manager.
