Costin Tanasoiu is a hands-on lead engineer and architect with 10 years of experience building scalable, cloud-native systems and delivering mission-critical projects across file-sharing and property-tech domains. Currently leading Trust & Safety engineering at WeTransfer, he designed content moderation and copyright detection solutions that process tens of millions of daily uploads and tightened reliability, testability, and compliance across services. He has a strong track record of driving post-acquisition integrations and cloud migrations at Hometrack, reducing large data build times dramatically and unifying identity and access across products. Comfortable both writing Terraform and Go services and coaching teams, Costin blends technical craft with organisational change—introducing Scrum, story-pointing, and engineering standards to improve delivery. He favors pragmatic selections of off-the-shelf solutions when they accelerate outcomes and routinely authors technical design docs and performance testing strategies to secure stakeholder buy-in. Based in the UK, he pairs deep backend expertise with a passion for mentoring and continuous improvement across CI/CD, observability, and TDD.
