Hi, I'm Lars Fronius 👋
Freelance Consultant for Cloud Compute architectures and software engineer (Go, Rust, Typescript)
As a freelancer I take a hands-on approach to consulting. 👨💻
With 15+ years of experience in compute architectures and software engineering, I can offer a holistic and generalistic approach to your software project.
My biggest area of focus is creating suitable solutions on Amazon Web Services (AWS). Explore my AWS services →
One of my strengths is translating simple ideas into complex technical requirements and complex technical concepts back into simple terms.
My passion is scaling products and organisations and maintaining a low cost of ownership. For most of my projects my clients come back for adding features, not for maintenance or outages.
After spending lots of time managing systems and servers, I believe serverless architectures will have beneficial trade-offs for most software projects. Learn more about serverless →

What my clients say
Laura Frank
VP of Engineering at CloudBees
“Lars is a strong engineer and technologist who is incredibly motivated and forward-thinking.
His deep command over AWS services and tools is a huge asset to the team, and he consistently advocates for using modern technologies to our stack.
Lars works very effectively independently but also finds his voice when working with or leading groups of engineers.
He’s highly regarded both inside and outside of our engineering team.”
Ramzi Rizk
CTO at EyeEm
“Lars joined us at a time when huge growth spikes were straining every part of our infrastructure, and he hit the ground running. He was able to build and launch quick and pragmatic changes to our infrastructure that helped us ride out the storm.
Throughout his tenure, Lars always understood the need to balance quick, pragmatic solutions to urgent problems with more thought out, resilient ones for longer term projects.
During his time at EyeEm, Lars helped automate and built key elements of our infrastructure, introduced proper monitoring, contributed to our feature development. Lars gave invaluable thoughts and input on our processes.”
Jilles van Gurp
Engineering Lead at Inbot
“Lars is an awesome product and people focused DevOps expert.
During the year he worked with us he worked both on our product and migrated our deployment infrastructure to AWS.
There are many ways to do this but with Lars we did it the right way and automated everything: VPN, infrastructure provisioning, builds, build promotion, networking, security, docker, rolling restarts, etc.
We were super impressed with Lars from day one and I would recommend him to any team that is serious about doing DevOps in a sustainable and scalable way.”
Rob van der Leek
Software Engineer at Kepler Vision Technologies
“Lars was a remote member of our engineering team for over a year now, building and designing the automation of our AWS infrastructure.
He takes the getting-things-done approach without cutting corners.
Very strong communication skills, both written and spoken, pleasure to work with remotely.
Very knowledgable and experienced when it comes to cloud environments, this allows him to estimate effort up-front accurately and deliver implementation quality.
Recommended!”
Sascha Krinke
IT-Leiter at Jacques' Wein-Depot
“Lars Fronius ist ein herausragender Partner und eine große Bereicherung für unsere Zusammenarbeit bei Jacques’ Wein-Depot. Besonders im Bereich Omnichannel hat er bewiesen, dass er komplexe Herausforderungen mit Weitblick und technischer Exzellenz angeht.
Seine Expertise im Aufbau skalierender Multi-Account-AWS-Architekturen nach Best Practices, kombiniert mit seinem tiefen Verständnis für serverlose Architekturen (DynamoDB, Lambda, API Gateway) und Infrastructure as Code (AWS-CDK), hat uns maßgeblich geholfen, innovative und zugleich kosteneffiziente Lösungen zu realisieren.
Hervorzuheben ist seine Fähigkeit, Architekturprojekte nicht nur technisch perfekt umzusetzen, sondern auch in bestehende Systeme nahtlos zu integrieren. Lars hat uns insbesondere bei der Entwicklung und Integration einer neuen Shop-Plattform beeindruckt – stets mit einem Fokus auf Qualität, Skalierbarkeit und die perfekte Abstimmung auf unsere Omnichannel-Strategie.
Lars überzeugt nicht nur durch sein technisches Know-how, sondern auch durch seine vertrauensvolle, offene und partnerschaftliche Zusammenarbeit. Wir schätzen ihn als zuverlässigen Ansprechpartner, der auch in herausfordernden Situationen stets die beste Lösung findet.
Ich kann Lars uneingeschränkt empfehlen und freue mich auf weitere gemeinsame Projekte!”
Gerd Doliwa
Engineering Manager at Scout24 SE
“Lars is a jack of all trades. Dedicated cloud engineer, strong software developer, CI/CD expert.
Applying engineering best practices to all tasks, never taking shortcuts, he creates scalable, future-proof and reliable solutions to all software problems.
As a team player, he is always there to support and coach his peers.
Due to his open and positive attitude, everybody enjoys working with him!”
