About Acun
React Engineer with 12+ years of production experience (6+ years React Native). I help product teams build and scale reliable applications — strengthening architecture, stabilising delivery, and contributing hands-on to implementation.
I typically join teams that need:
– Clean, scalable mobile architecture
– Stabilisation of existing React Native codebases
– Pragmatic integration of APIs and backend systems
– Improved release reliability and performance
– Close collaboration across product, backend and design
How I work:
Hands-on first. I value pragmatic collaboration, small iterations, and clear ownership. I’m comfortable guiding other developers when needed, while staying deeply involved in implementation.
Particularly interested in long-term product engagements (3–12 months) with continuous team contribution.
