Companies I have built software for
Client work
Selected projects
Three recent projects. Each one went from a blank page to production.
Electrical engineering · Manufacturing
A manufacturing control tool, built from scratch
Challenge
Planning and tracking of manufacturing ran on manual, scattered processes.
What I built
A web app to plan, steer and track projects, distribution boards, tasks and production progress. It has approval workflows, roles and permissions, file imports, notifications, ERP data and SSO with Microsoft Entra ID.
Result
The core manufacturing processes are now digital, transparent and easier to steer.
“He translated complex workflows cleanly into software and always paid attention to maintainability and quality.”
Services
How I can help you
I work end to end. You get one person who designs the system, writes the code and runs it on AWS.
Web apps & internal tools
From first idea to a web app in production. I work closely with you to solve the problem you actually face.
Typical tech stack: React & TypeScript · Hono REST API · PostgreSQL · SSO · Serverless-first AWS services
AWS platform engineering
A clean, secure AWS foundation that scales with you and stays cheap.
Landing zones · Security hardening · Cost efficiency · Infrastructure as code · Observability
AI in your product and your team
AI comes second. First you need a good application that solves your customer's problem. Then I build AI features for your customers and bring AI-assisted development into your team, so your developers ship faster and with confidence.
AI features with Amazon Bedrock · Agents behind your own API · AI in your software development lifecycle

Hi, I am Sandro
Before I went freelance, I was a data scientist at BMW and Check24, a cloud architect at Capgemini and one of the first engineers at Hashnode. I also build my own products, so I think like a founder, not only like a contractor. I love to take responsibility for what I build.

I teach what I build
I wrote two books on AWS, make videos on YouTube and speak at community conferences. That knowledge goes into every client project.
