Nikos Tzamos
Product-Focused CTO | Fast Execution, Real Outcomes
Greek, 32 years old, living in Sweden and Greece. ntzamos@gmail.com
I build products by staying close to both the code and the business need. I know when to move fast with a lightweight solution and when to invest in strong foundations. I work alongside the team, not above it, and I try to keep progress and people in balance.
Current Experience
Chief Technology Officer
Pandas.io Full-time
2019 - Present 6 years 3 months
I am currently leading the AI department, where I have created Vision products and services now deployed across major telecom retail networks. My work focuses on transforming device valuation and risk assessment through applied computer vision and automation, turning AI into real-world infrastructure that delivers measurable business impact. I collaborate across product, strategy, and partnerships to make sure what we build is actually used at scale and trusted in everyday operations.
Technical AI Advisor
Turn-Key.ai Part-time
2024 - Present 1 year 8 months
I support AI strategy and prototyping across voice, vision, and LLM-based systems, building fast proofs of concept that turn into real products. From vehicle damage assessment for insurers to enterprise tools for government agencies, I focus on making AI practical, reliable, and ready for deployment.
Past Experience
Lead Software Engineer at Deger (2017-2019)
Built and deployed IoT infrastructure across 150+ industrial sites. Developed backtracking software to minimise shadow impact on solar panels during early morning and afternoon hours, along with electricity production forecasting models, significantly improving energy yield and operational efficiency.
Software Engineer at Netcompany (2015-2017)
Worked on web platforms for EU public sector teams, with a focus on making heavy, form-based workflows actually usable. Spent a lot of time refining UI flows to reduce manual input mistakes and frustration, while keeping the backend fast and clean.
Software Engineer at Intale (2012-2014)
Developed modules for cashier display systems. Gained hands-on experience with enterprise development practices while shipping features that had to work reliably in busy store environments
