I work as an interim CTO and freelance full-stack engineer. I design and ship production platforms and AI integrations. I have built software professionally since 2015, from my own software projects to senior software engineer responsibilities in enterprise projects to leading engineering departments as CTO.

Selected industrial references

For reasons of discretion I keep all client relationships private and anonymize every case study.

Interim CTO for a daycare marketplace

A marketplace for finding daycare places, with an AI chat for each provider.

I built the initial architecture and developed the main features towards a product-market fit. Furthermore, I established engineering processes in the young and growing company. I hired and trained technical staff to make myself redundant.

Managing director and co-founder of a fashion brand

Shopify brand, design, administration and so on

Starting as a small online shop that I have built for my younger sister to gain practical experience next to her studies and to give her a fruitful ground for her bachelor's thesis (turned out to be the best possible grade 1.0), we continued growing the small business.

Outcome: Founded a legal entity in Germany for my family as a business and provided its initial funding

CTO for an e-commerce software company

Sep 2022 – Feb 2023

Led the distributed team of nine engineers in four countries that built the company's apps and platform, and restructured it for quality and stability.

Led the engineering team as the central point of contact for all nine engineers, and introduced Scrum and a new approach to agile ways of working
Reviewed code and aligned the backlog with the CEO
Led the migration of the apps from Cordova to Capacitor and rebuilt them in the process
Defined the API endpoints for new features
Unified services in the CI/CD setup to reduce technical debt
Restaffed the team: hired a QA tester and a designer while reducing resources elsewhere. The smaller team needed less management, so I could take over important frontend work myself.

“Look, I told you he can do it.”

“Thank you, Anton. I will never forget you.”

Outcome: Engineering costs dropped by more than half, while productivity, quality and stability improved. The apps became more user-friendly and the code easier to maintain.
Technologies: Vue.js, Nuxt, TypeScript, Capacitor, Kotlin, Swift, Spring Boot, Keycloak, MongoDB, Kubernetes, Docker

Lead frontend engineer for a rental machine software startup

May 2021 – Aug 2023

Co-founded a company building business software for SMEs that rent out construction machines.

Met the client regularly to define requirements
Designed the whole application architecture and its API endpoints
Designed the UI and UX

The business idea is reasonable and our software was great, but we lacked the experience (and frankly also the appreciation) for the sales part of a software company. So after a long period of hard work and limited success, we were happy to accept a takeover offer.

Outcome: Experience
Technologies: React, TypeScript, Next.js, Ionic, Capacitor, Cypress, Swagger, Kubernetes, Docker, MongoDB, AWS
