OPOX
Frontend development at a Münster digital agency: client projects for industry and public-sector clients — including the City of Dresden and BOSCH.
Three years at a Münster digital agency as a frontend developer. Focus: production-grade React and TypeScript applications for clients with high requirements around accessibility, performance and maintainability — from marketing sites through configurators to internal tools. Work in mixed teams with designers, backend engineers and client stakeholders; delivery on Scrum/sprint cadences.
Context
OPOX GmbH is a digital agency in Münster. Three years of full-time employment as a frontend developer — before co-founding Lemonverse and before the current product-engineering focus.
Clients (selection)
The client base ranged from public sector through industry to mid-market. The ones visibly recognisable — and so listable here — are:
Public sector
Stadt Dresden
Frontend work on web applications for the City of Dresden — with the corresponding requirements around accessibility, data protection and browser reach.
Industry / enterprise
BOSCH
Frontend contributions to BOSCH projects within a mixed agency team — components, integrations, stakeholder handoffs on Scrum cadences.
Focus areas
Production frontends with React + TypeScript
Components, state management, routing, API integration. Code that survives multiple releases and doesn't need to be thrown out at the first client change.
Accessibility & performance
For public-sector clients WCAG conformance and fast initial loads weren't a nice-to-have — they were an acceptance criterion for delivery.
Work in an agency setting
Mixed teams of designers, backend engineers and project leads. Tight iteration with client stakeholders, sprint-review handoffs, code review across the team.
Build pipelines & deployment
Webpack-based setups, CI/CD integration, handoffs into staging and production stages with branch-based workflows.
What stuck
- Three years of hands-on experience with enterprise frontends in Scrum teams — from concept to production.
- Client-stakeholder communication on sprint cadences, including review meetings and demos.
- First in-depth practice with modern TypeScript / React, which later carries Lemonverse and the personal products.
- Understanding that frontend maintainability matters more than the coolness of the next framework.
Note
Concrete project outputs belong to the respective clients — details on individual applications are subject to the relevant agreements and are not broken down publicly here. Happy to walk through specifics on request.
