Ștefan Olaru is a hands-on CTO and cloud architect with 13 years of experience building scalable, cost-efficient platforms and high-output engineering teams from the ground up. He has taken products from MVP to enterprise—driving 5× infrastructure performance at 25% cost and cutting release time by 90%—and brought pragmatic AI and GDPR/HIPAA-compliant solutions into conservative finance and healthcare sectors. As a fractional CTO and consultant he repeatedly modernized fragile systems, migrating workloads to serverless and trimming infrastructure costs up to 75% while preserving production reliability. Based in Iași, Romania, he blends an architect’s precision (BArch) with deep AWS expertise (8× certifications) and a founder’s mindset—co-running a profitable marketplace for 15 years—so his teams ship what actually survives real-world constraints.
