Senior🎓
Top SchoolTomas Sivicki is a Senior Consultant Developer with 11 years of hands-on full-stack experience crafting modern JavaScript/TypeScript applications and developer-friendly architectures. He has delivered production frontends and backends across industries—from mining and cable assembly to water research and insurance—often improving operational workflows and content management for B2B customers. Comfortable in React/Redux, Node.js, GraphQL and DevOps tooling, he repeatedly turns greenfield and legacy projects into maintainable, testable systems and has shipped PSD2-compliant banking and microservice-based cable assembly platforms. At ThoughtWorks and prior consultancies he blends rapid prototyping with long-term handovers, and his curiosity drives ongoing learning in Rust and crypto technologies.
