Andrei Bahamolau, Full Stack Engineer

About

🚀 Engineering Leader & Software Engineer with 12+ years of experience building and scaling products across FinTech, Environmental Tech, AdTech, Audio Streaming and E-commerce domains. I have around 6 years of leadership experience, leading engineering teams, driving architecture decisions and delivering complex platforms end-to-end – from discovery to production launch and iteration. I believe great engineering cultures are built on ownership, clarity, and trust. I create environments where developers feel empowered to make decisions, take initiative, and act as product owners – not just task executors. My focus is on supporting engineers to grow, ensuring high engineering standards and delivering user-centric value, not process for the sake of process. While my core expertise is in TypeScript/Node, React, and cloud architectures, I've worked across multiple stacks (including Swift and Java/Kotlin) and have consistently adapted quickly to new technologies and environments. As an engineering leader, I don't need to know every tech upfront – I know how to learn fast, set direction and enable teams to succeed. Core strengths: • Technical leadership & system architecture • Empowering teams and building ownership culture • API-driven platforms and distributed systems • Hands-on mentoring & raising engineering standards • Bridging technical and product decision-making • Fast adaptation to new tech and domains ⚒️ My main tech stack is: ☑️ JavaScript, TypeScript ☑️ React, Recoil, Redux ☑️ Node.js ☑️ Nest, Express ☑️ GraphQL (Apollo), Rest API, WebSockets ☑️ MongoDB, PostgreSQL, MySQL, CosmosDB ☑️ Jest, RTL, Cypress, Playwright ☑️ Docker, Kubernetes ☑️ AWS, GCP, Azure ☑️ Microservices, Microfrontends ☑️ CI/CD pipeline such as Gitlab, GitHub Actions, Circle CI ☑️ Event-Driven Architecture, Data Pipelines ☑️ And much more! 🔍 Open to Engineering Manager or Tech Lead roles 📍 Europe / Remote 🧾 B2B contract 💼 Also available for technical consulting (architecture reviews, MVP launches, scalability and performance work) If you're building something ambitious and want a leader who combines strong engineering fundamentals with a people-first, ownership-driven approach – let’s connect.
