Frontend engineering & web application development

[Draft note for Manuel]: pulled out of "Custom software development" as its own line item — your Tech Profile already lists 9 years of Frontend (React/TypeScript/Angular/RxJS) as its own stack card, separate from Backend, so it made sense to sell it separately too. Confirm the framing below matches how you actually want to position frontend-only engagements vs. fullstack ones.


Not every project needs a new backend — sometimes what's actually slowing a team down is the frontend: a UI that's hard to change without breaking something else, state management that grew organically instead of by design, or a design system that never quite got built. I build and untangle frontends that are meant to survive contact with a real product team, not just a demo.

Most of this work happens in React and TypeScript, with Angular for teams already committed to that ecosystem. What that looks like in practice:

  • Component architecture that a team can extend without stepping on each other — clear boundaries between UI, state, and data-fetching.
  • Real state management (not everything needs a global store), and performance that holds up once the app has real users and real data, not seed data.
  • Accessibility and responsive design treated as part of the build, not a pass at the end.
  • Integration with an existing backend and its API contract — this pairs naturally with API design & integration work when the two sides need to be designed together.

This is standalone frontend work, distinct from a full custom software build — useful when the backend already exists, or when a team specifically needs frontend depth added to what they already have.

Got a frontend that's become hard to work with, or a new product that needs one built right? Let's talk.
