Hi! 👋 I'm Javier Cicchelli, a freelance tech lead and software engineer from Amsterdam 🇳🇱, working as Röck+Cöde. Seventeen years shipping mobile products across every Apple platform, Android, web and the services behind them — and just as long leading the teams that build them. Hire me to build your product from scratch, rescue the one you have, or lead the people building it. Either way, I'm in the codebase, not just the meetings.
What I can do for you
01
I audit your stack, team and roadmap, then write the plan: which platforms, in what order, with what people. You get a document the board can read and the engineers will follow — and I stay to get it started.
For founders, CTOs and product leads choosing what to build next
02
I lead your mobile team from inside the codebase: planning, reviews, releases, one-to-ones, hiring. Delivery becomes predictable, stakeholders get straight answers, and the engineers grow — because I am still writing code next to them.
For teams between leads, or growing faster than their processes
03
I design and build native apps in Swift, and Kotlin where it's needed, from first commit to the stores' review — sharing one codebase across platforms wherever it pays off, and handing over code your team can own.
For companies launching on any Apple and/or Android device
04
I build the backends-for-frontends and server-side services with Swift, plus the web and hardware third-party integrations the app depends on — so the whole product ships as one piece, not a client waiting on a server.
For product teams whose app depends on services, hardware, or both
05
I move legacy code forward without stopping the release train: Objective-C to Swift, UIKit to SwiftUI, one tangled target to modules — incrementally, with tests and CI in place, while features keep going out.
For teams whose codebase has outlived its architecture
Most engagements mix at least two. Tell me where it hurts on the first call, and I'll propose the shape.

How it starts
01
Day one
A 30-minute call about what you're building, where it's stuck, and whether I'm the right fit.
02
Within a week
A one-page proposal — approach, shape of the engagement, cost — with nothing to sign yet.
03
Next sprint
I join your team — your tools, your rituals, your codebase — and ship something in the first week.
No fit? I'll say so on the call, and point you to someone who is.
What clients say
“I knew I could always count on him to deliver exactly what we spoke about, exactly when he said it would be done.”
Rock & Roll
Tell me what you're building, where it's stuck, and when you need it.
