Software Engineer // Web & Systems Craft
Software engineer with production experience in Vue.js, React, and TypeScript. I spend most of my time on client-side state management, local-first persistence, and keeping memory footprints small.
Currently doing a Master's in systems engineering in Germany. I study what happens under the browser engine, building tools that work without a network connection.
LEXICON_&_ENGINEERING_CRAFT
Defined core technical inquiry areas- 01.01 CLIENT_ARCHITECTURE
-
Building reactive UIs in Vue.js, React, and TypeScript. Mostly dealing with state isolation, async data flow, and keeping things at 60 FPS without fighting the framework.
#ui-craft - 01.02 LOCAL_FIRST_&_OFFLINE
-
IndexedDB, service workers, local schemas. The goal is software that works instantly without a network roundtrip and keeps user data on the device.
#local-first - 01.03 SYSTEMS_FOUNDATIONS
-
Master's studies in computer and systems engineering. Researching OS scheduling, memory layout, and network protocols underneath the browser engine.
#systems - 01.04 RESILIENT_DATA_FLOWS
-
Client-server interfaces that handle dropped connections, partial failures, and event-heavy streams without losing user state or corrupting mutations.
#resilience - 01.05 PRAGMATIC_DISCIPLINE
-
Standard web primitives over framework abstractions. Lean bundle budgets, clean types, and knowing when not to add another dependency.
