Ąžuolas Saulius Balbieris

I’m a Software Systems student at Kaunas University of Technology focused on software engineering, data analysis, machine/deep learning workflows, and practical product building. I have hands on experience building Android applications, API-based tools, data projects, and local-first software systems. I previously worked remotely as a freelance Android developer, shipping apps across education, language learning, and finance. That gave me practical experience with Kotlin, Android, REST APIs, authentication, external integrations, clean UI structure, and maintainable app architecture. My current technical focus is Python, machine/deep learning, data analysis, TypeScript, Next.js, and well maintained agentic software development. I have worked on statistical analysis, API-based data collection, Web3 research, local dashboards, automation tools, and developer workflows. Most notable projects: - Built Web3 trading data pipelines for collection, preprocessing, validation, backtesting, risk metrics, and execution research - Shipped Android mobile apps for education, language tools, and finance - Built a SaaS Chrome extension for trading video game items, reaching about €1k profit before deciding the market was too weak to continue - Built Etsy store fulfillment automation supporting roughly €2k MRR - Built multiple open source agentic development tools, including rag-sync, mind, imp-agent, and archflow Outside formal work (which I enjoy), I care a lot about sports, self improvement, and building a life where I keep getting better in every area. I train calisthenics daily, stay active, and windsurf whenever the wind is right. I’m looking for remote junior roles, internships, part-time work, or contract opportunities in software engineering, Python development, data/ML, AI evaluation, QA/data quality, or technical product building.
