Caroline Marquessoftware engineer
Hi, I’m Caroline.

Curious by nature.
Engineer by choice.

I’m a software engineer based in Munich. This is where I share what I’m building, learning, reading, and playing—with a little of my professional life mixed in.

BASED IN MUNICH

Cool things I’ve done :)

01

Home charging.
Handled end to end.

I built a way for fleets to reimburse drivers for charging company EVs at home. I owned the feature across the stack: matching vehicle telemetry to home locations, calculating reimbursements, and giving managers the tools to review and export them.

02

A new language.
A wider reach.

I led the Japanese-language rollout from the initial idea to production, bringing our platform to Japanese-speaking customers. I took ownership of the localization initiative and carried it through engineering and final delivery.

03

Stronger security.
Proven in production.

I worked directly with security specialists to turn pentest findings into production fixes, strengthening password recovery, tenant isolation, and access controls. I owned critical remediation from investigation to delivery, contributing to the company’s successful ISO certification.

04

Safer deployments.
Fewer lasting secrets.

I drove the migration from long-lived AWS keys to short-lived credentials through GitLab OIDC, standardizing deployment authentication across our services and reducing reliance on stored cloud credentials.

CURRENTLY TINKERING WITH

AI, closer to home.

A personal project in progress

I’ve been getting deeper into AI, and I’m already building a local setup at home. I’m using Ollama to run language models on my own hardware, with the goal of giving my apps and personal assistants a shared AI backend—and eventually connecting it to home automation.

My first app is a personal grammar assistant. I’m building it to catch mistakes, suggest clearer wording, and help me soften my tone when needed. It’s a project I get to learn from and use myself.

It’ll be on GitHub soon. Stay tuned!

OFF DUTY

Away from the keyboard.

On the wall

You can find me bouldering V5s and V6s, working out the next move.

I’m also learning German. Slow but steady!
