Frontend Architect

I designed the architecture of a modern microfrontend development stack in a monorepo for a suite of applications and shared packages, and led the key technical decisions throughout its implementation. Together with the team, I developed React applications for entity management, inheritance proceedings, and related administration. As part of the platform, I introduced Stencil and built a cross-framework design system, including React/Vue wrappers, Storybook documentation, and visual testing. The development stack also included a Node.js Fastify backend acting as a BFF/gateway: it handled authentication and session management for the templating service via a session cookie, with JWT managed server-side in Redis and TTL derived from token expiration. It also provided proxying for frontend modules and internal APIs, request tracing, CORS, compression, cache headers, and static build serving. I standardized the API layer by generating the client from OpenAPI and integrating type-safe runtime validation using Zod schemas generated from OpenAPI. For deployment, I prepared Docker builds with a production image based on Google Distroless.

Senior Frontend Developer

I worked on a product suite for fleet & tire management—primarily on the INCENTER 2.0 and INFLEET applications, as well as other related apps across the platform. Shortly after joining, I initiated the introduction of JWT-based authentication, strengthening the overall security of the application. I contributed to the migration from Vue 2 to Vue 3, the transition from Cordova to Capacitor, and the move from the legacy backend to a new custom ORM on Node.js, including further development of a GraphQL API built with Apollo on Azure Functions with data stored in Azure Cosmos DB; besides frontend work, I also implemented parts of the API. My work also included refactoring, code reviews, and continuous improvements in stability, performance, and maintainability.

External Frontend Team Leader

As a consultant working through an external agency, I took over the frontend project and development stack from a different vendor agency. My role was to stabilize development, map the architecture, establish standards, and ensure knowledge transfer so the internal team could continue developing the product independently long-term. This included technical leadership, mentoring, code reviews, and documentation.

External Frontend Team Leader

On a greenfield project, I designed and set up the development stack and ways of working from scratch to ensure the product could be developed sustainably over the long term. I introduced clear engineering standards (code quality, review workflow, testing, and consistent UI practices) so the team could deliver predictably without unnecessary technical debt. As an external Frontend Team Leader, I built up the internal frontend team—leading technical interviews, onboarding, mentoring, and ongoing code reviews—and gradually handed over ownership and know-how so the team could continue developing and scaling the product independently.

Senior Frontend Developer

I contributed to the development of a customer portal for Asahi, including integration with the Salesforce ecosystem. I focused on implementing key features in Vue 3 and integrating with a GraphQL API. My work also included building and maintaining web components (LitElement), refactoring, code reviews, and continuously improving code quality and maintainability. During a demanding period, I worked overtime when my schedule allowed to help keep delivery on track under increased workload. I also made a small contribution to hiring by conducting one targeted frontend interview.

Frontend Developer

I worked primarily on a project for MONETA Auto — a vehicle financing application. I contributed to rewriting a legacy desktop application (originally from 1999) into a modern web frontend built from scratch. My work included designing and implementing key parts of the React application, state management (Redux, Redux Saga, Reselect), establishing a component workflow (Storybook, Pattern Lab), and continuously improving code quality (tests, refactoring, code reviews).

Frontend Developer

In an agency environment, I contributed to the development of web portals, campaigns, and prototypes for various clients. For ČSA and MediaGuru, I worked on new portals built on Umbraco CMS and ASP.NET Razor. For Allianz, I developed a prototype of an offline insurance system for internal consultants, including offline capabilities (IndexedDB/Web Storage) in AngularJS. For ČSOB Pojišťovna, I optimized the insurance purchase form to improve usability and conversion. I also contributed to projects such as the MONETA mortgage portal hypoteka.cz, the De’Longhi “Secrets of the Coffee” campaign site, and Benzina’s 60th anniversary website.

Full Stack Developer

I worked on the ESC (Embryo Score Compare) application and the elearn.aero portal focused on English training for pilots. I also contributed to Simple Dent (simpledent.cz), a cloud practice-management system for dental clinics. I delivered new features and maintained the solution primarily on the React frontend, and also on the backend in Nette (Latte/Doctrine).
