Software & Cloud Engineer · Hannover, DE
I build software people actually use, and now I'm building products of my own.
Python developer and Azure cloud engineer. I've spent years shipping apps for clients, communities and myself. Now I'm turning that experience into SaaS products that do one job really well.
01Now building
After years of building for others, I'm building my own tools. Each one starts with a real problem I've seen up close.
German e-invoices that pass validation the first time.
For freelancers and small businesses facing Germany's E-Rechnung mandate. Create XRechnung and ZUGFeRD invoices, check them against the official EN 16931 rules before they go out, and keep a tamper-evident record of every invoice you issue.

Tell me when it's readyShared costs, split fairly, with every cent on record.
For associations, tontines and mutual aid groups that still track contributions in a spreadsheet. Each member gets a wallet; when a cost comes up, it is split across active members in one step, shortfalls are flagged, and every movement lands in an auditable ledger.

Tell me when it's ready02Story
I'm Alex. Online you'll usually find me as Zaker. I'm a software and cloud engineer living in Hannover, Germany.
Most of my days are spent in Python and on Azure: designing backends, automating the boring parts, and making sure things keep running at 3 a.m. without anyone noticing.
Outside of work I build in the open. With OSS Cameroon I've worked on tools for the developer community, like Jobsika, where people share salaries anonymously. I also built Scoreboards, a live-score platform for Cameroonian football.
Away from the keyboard, I run. I started in 2020 and now I'm out three to five times a week. In April 2026 I finished my first marathon in my home city, in 3:43:55.
Now I'm taking the next step and building my own SaaS products: small, focused tools that solve one problem well, made with the care I'd want as a customer.
03Selected work

JobSika is a website that allows people to anonymously rate their companies and share their salaries, in order to create a more level playing field between employers and employees. People can contribute their salary information to the website and help to change the current narrative around salary information.

04How I work
APIs and backends that stay boring in the best way, and interfaces people don't need a manual for.
Turning the work people do by hand into workflows that run on their own, and keeping systems in sync.
Practical AI and clean data where they actually help the user, not just because it's trendy.
Infrastructure that deploys itself, scales when it has to and tells me before something breaks.

Comment Scoreboards utilise un classement Elo, recalculé après chaque match, pour estimer les probabilités de victoire, de nul et de défaite des matchs camerounais, et pourquoi le modèle bat les approches naïves.
