Kamil Oczkowski
Staff full-stack engineer, seven years in. I build the platforms behind sites used by two million customers.
Next.js and Vercel migrations, a design-token system shared by designers and engineers, a company-wide Auth0 rollout, and the delivery pipelines that let eight squads merge tested features straight to main.

experience
- 2026 → nowStaff Engineer
Technical lead across 8 squads and around 40 engineers in the go-to-market team. Led the migration of every customer-facing site to Next.js and Vercel, the design-token system behind them, and the company-wide move to Auth0. Cut AWS costs by 40%.
- 2024 → 2026Lead Frontend Engineer
Directed a cross-functional team through a major application refresh, owning delivery end to end. Improved TTFB, asset sizes and layout shift, and cut time to delivery from days to hours by removing the release ceremony and merging e2e-tested features straight to main.
- 2023 → 2024Senior Frontend Engineer
Rebuilt deployment pipelines, cutting runtime from around an hour to 12 minutes, and built a rollback mechanism that reverts or freezes deployments when observability alerts fire. Led the design-system proof of concept and mentored junior and mid-level developers.
- 2022 → 2023Mid-Level Frontend Engineer
Rebuilt the navigation system on Contentful and made it fully accessible, with ESLint and Axe enforcing the standard. Led a major dashboard rewrite.
- 2021 → 2022Mid-Level Frontend Engineer
Built a digital asset management platform used by brands such as Universal, Morrisons and Heinz, including its multipart upload tool for media up to 20 GB. Refactored legacy code to improve performance and fix bugs, then rebuilt the product's front end from scratch for release.
- 2019 → 2021Junior Frontend Engineer
Client triggers and proofs of concept, Webpack tree shaking and bundle splitting for client tags, internal analytics dashboard widgets.
