( process )

How I ship.

phase 00 / 05

phase 01 — listen

Listen.

The brief is rarely the real problem.

Interviews, support tickets, session recordings. I sit with the people who will live in the product before I draw a single frame.

User interviewsJourney auditProblem framing

“Where do I find the magic question?”

user story

“I just want to explore first.”

interview 04

“I got lost three screens in.”

session recording

phase 02 — map

Map.

Rough first. Real soon after.

Problem, rough design, MVP, test, iterate then round again. Edge cases and engineering constraints join the map on day one, not after handoff.

Product loopUser flowsTech constraints

phase 03 — design

Design.

Systems before screens.

Tokens, components and motion specs in Figma, prototyped until the interaction feels inevitable rather than decorated.

Design systemPrototypesMotion specs

phase 04 — build

Build.

The same hands write the code.

React, React Native and Next.js in production, so nothing is lost in translation between the file and the feature.

phase 05 — ship

Ship.

Launch opens the feedback loop.

CI, preview deploys, TestFlight and analytics wired from the first sprint. Real usage decides the next iteration.

In the arena.

Hackathons, certifications and rooms I chose to be in. The work that happens after hours is where most of my instincts were built.

01 / 05

Google Professional Machine Learning Engineer

Google Cloud · Remote · 2026

Two hundred flashcards deep and still going. Pipelines, model serving, feature stores, MLOps at scale, racing the curriculum while building the instincts that matter more than the badge.

Yolked AI → Minotiq

Bolt · Distributed (Remote) · 2025

What started as a fitness logging app between four people in four time zones turned into something much bigger, a pivot mid-hackathon, a product that could actually run a gym.

Navel Robotics. Headless IoT on Captive Networks

Navel Robotics · Munich, Germany · 2026

Navel is an empathy robot deployed in care facilities across Germany. Getting it online at each new site meant solving a problem hardware vendors rarely talk about: captive portals.

Start Sprint — Contxt

Start Berlin · Berlin, Germany · 2025

Alice Zhai had the raw material. I had the product frame. In the Start Sprint we turned a half-formed idea into something pitch-ready and walked out as one of the selected teams.

MyVital — Emergency Care for Chronic Conditions

Rwanda Coding Academy · Nyabihu, Rwanda · 2023

Five people, one idea that kept getting bigger: what if the moment a chronic patient needs emergency help, everyone who matters hospital, insurer, doctor already knows exactly what to do?

Volunteering · 2023 – Present

Brainiacs

Taught teenagers to code while figuring out a lot of it myself. The classroom became a mirror, they pushed me as much as I pushed them. Watching students with no personal computer build things from scratch stays with you.

Start Berlin

Found my Berlin footing here. Builders, makers, early believers people who take early-stage seriously. I show up, help on the ground, and always leave with a sharper read on how this city's startup ecosystem actually works.

( 05 ) about — me

I care about the details.

My first encounter with a laptop changed everything. Years immersed in software engineering and embedded systemsreal hardware, real code, building real hardware and writing real code before I knew the rules. Today I sharpen that craft at CODE Universitysoftware, design, product. That foundation made me dangerous in the best way. I think in systems, ship in sprints, and refuse to treat designone pair of hands and engineeringone pair of hands as separate concerns. Now deep in the startup worldbuilders, early believers, doing the kind of work that actually ships and actually matters.
