I help companies build, modernize, and scale complex Android apps and SDKs when internal teams run into architectural, performance, or delivery bottlenecks. I work as an external Android consultant and step in where senior technical direction is needed without hiring a full-time employee.
I specialize in designing and refactoring Android architectures, building and hardening SDKs and internal libraries, and leading major migrations from legacy stacks to modern Kotlin-based solutions. My work often involves Clean Architecture, modularization, Jetpack Compose, Kotlin Coroutines/Flow, and Android performance and stability improvements.
I have more than 8 years of experience working on Android apps and SDKs across healthcare, finance, telecom, logistics, and mission-critical environments. I am comfortable working on regulated systems, Bluetooth and IoT integrations, and long-term B2B engagements with distributed teams.
In recent roles, I have acted as an external technical lead, coordinating delivery, mentoring developers, reviewing code, and supporting CI/CD pipelines. I have also contributed to Kotlin Multiplatform initiatives and helped teams modernize legacy Java/RxJava codebases into scalable Kotlin solutions.
My background includes leading Android development for startups and enterprise clients, building Bluetooth synchronization SDKs, developing MCPTT and QR-based solutions, and supporting apps used in high-availability environments. I value maintainable architecture, reliability, and practical engineering decisions.
I am based in Spain and available for remote B2B Android consulting for EU and US clients. I bring a strong mix of hands-on development, technical leadership, and cross-functional collaboration to complex mobile projects.
