About Guido

Senior Android Developer and Tech Lead with over a decade of experience delivering complex mobile products - from smart locks and EV chargers to OTT streaming platforms used by millions.



I work in Kotlin daily, applying Clean Architecture, Coroutines, Flow, and Jetpack Compose to build maintainable, scalable codebases. I move naturally between leading a technical design meeting, mentoring a junior through a code review, or getting deep into a refactor that's been haunting the repo for a long time.



I've led features and projects across multiple companies, collaborating closely with product, design, firmware, and architecture teams to deliver robust end-to-end solutions. I also have direct experience advising early-stage startups on mobile strategy, stack selection, and MVP scoping.



🤖 Lately, I've been leaning hard into AI-assisted development: spec-driven-development, Claude, Cursor, agent tooling, and LLM-powered automation: I genuinely believe it changes what a focused team can deliver.



📲 If you're building a mobile product, scaling an Android team, or looking for senior technical leadership - let's talk. I'm always open to interesting conversations.
