Radomir Wojtera
Staff / Lead Frontend Engineer | React, Next.js & Developer Tooling
About Me
15+ years of engineering experience architecting scalable React applications, robust CI/CD pipelines, and high-performance B2B SaaS tools. TypeScript-first architecture, state management, and design systems — backed by test automation (Cypress, Jest) that keeps enterprise releases safe on every deploy.
Key Competencies
Frontend Architecture
- React, Next.js, TypeScript, State Management, Design Systems, Tailwind CSS
- Micro-frontends, bundle-size optimization, high-performance enterprise UI
Quality, Testing & DX
- Cypress, Jest, CI/CD Pipelines (GitHub Actions), Docker, Test Automation
- Design-for-testability and DX automation that remove friction from frontend workflows
Backend & Integrations
- Node.js, Nest.js, Spring Boot, Kotlin/Java
- REST & GraphQL API design; schema-first integration with enterprise backends
Engineering Leadership
- Team mentorship (4–5 devs), technical hiring, code reviews, architecture documentation
- Agile process ownership and React adoption across teams
Featured Work
Most production work lives in private enterprise repos; below are representative systems I own or architected.
Enterprise Back-Office Platform — React · TypeScript · State Management · CI/CD
- Own ~95% of a high-traffic internal operations console; refactored legacy views into a type-safe, scalable React architecture.
- Consolidated state management and a shared design system, cutting duplication across modules and accelerating feature delivery for ops teams.
- Added Cypress + Jest coverage over critical workflows and automated releases with GitHub Actions to de-risk every deploy.
Event Visualization Engine — React · Interactive Canvas Components · Pluggable Architecture
- Architected the pluggable interpreter layer so the rendering core stays domain-agnostic — new data formats plug in as typed adapters with zero engine changes.
- Built for high-frequency event streams and complex dashboards; canvas-based rendering powers interactive, high-performance enterprise visualization.
Internal Developer Tooling — React · Kotlin · Build Pipeline
- 100% ownership: rebuilt the complete admin UI and designed the build/deploy pipeline for an internal developer server.
- Hardened the Kotlin backend — endpoints, schemas, entities — ramping Kotlin through AI-augmented engineering.
- Pipeline automation lets teams ship tooling updates reliably instead of fighting deployments.
Additional contributions: API endpoints, schemas, and comprehensive tests across internal platform services (Node/Nest, Spring, Kotlin) plus a customer support suite; champion of API documentation and visible progress tracking.
Career Highlights
- 15+ years in software engineering — early career in Java/PHP, deep specialization in React/TypeScript architecture over the last several years.
- Technical Lead (3 years): guided a team of 4–5 developers through agile workflows, architecture decisions, and code review standards.
- Institutionalized test-first and AI-augmented development practices; mentored developers in React best practices and modern workflows.
- Active contributor on Stack Overflow and Codewars.
