About Daniel
I help companies build, modernize and scale complex Android apps and SDKs when in-house teams hit architectural, performance or delivery bottlenecks.
I work as an external Android consultant, supporting teams that deal with:
•large or legacy Android codebases
•internal or public SDKs
•Bluetooth / IoT integrations
•mission-critical or regulated environments
•teams that need senior technical direction without hiring full-time
What I usually do:
•Design and refactor Android architectures (Clean, modular, data-driven)
•Build and harden Android SDKs and internal libraries
•Lead complex migrations (legacy → modern stack, XML → Compose, Java → Kotlin)
•Unblock teams on performance, stability, memory or BLE issues
•Act as temporary technical lead or senior consultant for Android teams
Background:
•7+ years working on Android apps and SDKs
•Experience in healthcare, finance, telecom and critical systems
•Strong focus on Kotlin, Jetpack Compose, BLE / IoT and maintainable architectures
•Used to working with distributed teams and long-term B2B contracts
Engagement model:
•B2B contracts (EU / US)
•Remote-first
•Short or long-term collaborations
If you need an external Android specialist to solve hard problems without onboarding a full-time employee, feel free to reach out.
Available for B2B Android consulting (EU / US, remote).
