Summary

👤
Senior
Gosha Spark is a seasoned full-stack software engineer and freelance consultant based in New York with 14 years of experience building MVPs, custom web apps, and mobile apps (React Native). He’s helped startups and products ship faster and reduce tech debt through front-end leadership roles at Gumroad and internal tooling work at Lyft, while also maintaining Rails backends for long-running projects. Comfortable across the stack, he contributes to both UI/UX improvements and core runtime functionality—his open-source work ranges from enhancing Ember and build tooling to implementing Ruby Hash methods in a high-performance Ruby implementation. Clients value his pragmatic approach to turning vague product needs into prioritized, deliverable plans that respect time and resources. He’s particularly strong at modernizing legacy codepaths and improving developer workflows (HMR, bundling, build systems), which often accelerates delivery beyond feature work alone.
