About

I solve hard problems by building real systems.

Not decks. Not prototypes. Production software that people depend on, in environments where failure has consequences.

Michal Kwiatosz

My path from intern to technical lead went through COVID-19 production ramp-ups, building data teams from zero, and digitizing manufacturing across three continents. Each role demanded a different shape: sometimes I'm writing the algorithm, sometimes I'm designing the architecture, sometimes I'm aligning the people.

What I've Built

Six years. Three continents.
One mission.

Squad Leader / Senior Data Analytics Specialist

Mar 2022 - Present

Santa Clara, Silicon Valley · Rotkreuz HQ, Switzerland

Building an Operations and R&D data platform for manufacturing of a next-generation sequencing system. Connecting granular supplier data (wafers, chips, chemical processes), manufacturing execution, and quality control into a single intelligent system.

  • Designed and shipped a unified data platform integrating complex supply chain data, working hand-in-hand with suppliers, procurement, and supply chain teams to connect wafer, chip, and chemical process data
  • Developed algorithms and data analysis pipelines for image recognition, sequencer data, and anomaly detection across the production pipeline
  • Created an E2E system delivering faster insights across all levels, from shop-floor operators to senior management, enabling root cause analysis, yield optimization, and process improvement
  • Led and grew a high-performing squad with 99% positive reviews. Built a culture where cross-functional collaboration thrives and every team member's contribution is valued
  • Navigated the extreme complexity of regulated NGS manufacturing: fast-paced, demanding, technically deep, and zero margin for error

Delivered the data platform for a next-generation sequencing system that went on to set a Guinness World Record for fastest DNA read. Learn more

Data Scientist

Aug 2021 - Aug 2022

Cape Town, South Africa · Rotkreuz HQ, Switzerland · Santa Clara, USA

Factory of the future: started the digitalization effort from scratch at a manufacturing site with no existing data infrastructure, no team, and no playbook.

  • Built a data team from scratch, hiring and mentoring data scientists and engineers on-site
  • Started the entire digitalization effort from zero, establishing data collection, pipelines, and analytics capabilities
  • Drove yield improvements by connecting process data across manufacturing steps and enabling data-driven root cause analysis
  • Mentored scientists and engineers to think in data pipelines, not Excel exports, creating lasting data citizenship
  • Eliminated bottlenecks by automating data flows and optimizing database queries
  • Bridged continents: built partnerships that turned remote collaboration into a strength, not a constraint

Took a site from zero data capability to self-serve analytics. Yield went up, manual work went down, and the team kept growing after I moved on.

Data Scientist Consultant

Jul 2020 - Aug 2021

Rotkreuz HQ, Switzerland

COVID-19 testing ramp-up: build a data team and infrastructure from zero under extreme time pressure.

  • Built a data team from nothing: cross-departmental, cross-functional, scrappy
  • Designed data collection systems and KPIs that exposed invisible quality issues
  • Root cause analysis that stopped recurring six-figure losses

60% warehouse space reclaimed. 12 hrs/week of manual work gone. Significant financial losses caught and stopped.

Full Stack Developer Intern

Oct 2019 - Jul 2020

Rotkreuz HQ, Switzerland

First real engineering role: build a web application, wear every hat, ship something that matters.

  • Built a web app that replaced a days-long manual process with minutes of automated analysis
  • Designed the UX, set up the DevOps, ran the sprints as Scrum Master
  • Proved that an intern with drive can ship production software that the whole team depends on

Launched. Adopted. Still running. The beginning of everything that followed.

Ready for the
next hard problem.

Philosophy

Principles that
shape the work.

The ultimate currency in the universe is knowledge.

I don't build dashboards. I build systems that make people smarter about their own processes. The platform is the product only if it generates understanding.

It's easier to work on a hard, meaningful project than a simple, meaningless one.

The most meaningful moment isn't shipping the feature. It's when a manufacturing operator says "this actually helps me find the problem faster," or when management can finally see the full picture, or when the data reaches a patient sooner. That reaction is the fuel.

You don't have direct access to reality - no one does.

Every person sees the world through their own unique lens. That's not a bug, it's a superpower. In a team, the best decisions come from combining perspectives that no single person could hold alone. If you're curious about this idea, read "What Is It Like to Be a Bat?" by Thomas Nagel.

Whether you think you can or can't do something, you're right.

Beliefs shape capabilities more than most people realize. I've seen teams transform not because they got new tools, but because they started believing the problem was solvable. Mindset is infrastructure.

Conflict is mostly the result of people not being understood - by others and often by themselves.

Being open and communicating clearly isn't a soft skill. It's the hardest engineering problem in any cross-functional team. Most friction I've seen wasn't about disagreement. It was about people not feeling heard.

Everything in this world has been created by people like you.

No gatekeeping. I went from intern to technical lead by showing up and building things that worked. The barrier to creating something extraordinary is lower than people think.

Team spirit wins.

Three countries, three continents, one system. 99% positive squad reviews. The technical architecture matters less than whether the people building it actually understand each other.
