李思瑞

Software & DevOps Engineer

I build things for the web, quarrel with servers, and spend an unreasonable amount of time making sure deployments don't break. When things do break (and they will), I've gotten pretty good at reading logs/traces and pretending I knew what the issue was all along.

Most of my time goes into learning 汉字/Mandarin and working on projects that'll hopefully see the light of day or discussed here.

The journey of a thousand commits begins with a single PR, or something like that.

Nanchang, China

Always up for interesting conversations

What I'm working on

Embedded systems & low level programming
Learning and experimenting with C/C++, currently working on designing and re-implementation of a Micromouse (an autonomous maze-solving mouse). The documentation journey will live here.

Clubs for Internationals (老外)
Helping set up and pioneer for clubs, focused on knowledge sharing and practical computer science projects among Internationals.

Learning Mandarin
Actively studying Mandarin focusing on conversation, tone accuracy, and everyday chatter.

What I was up to

Africa Quantitative Sciences (Kigali, 2025)
Helped build health resource tracking systems for national infrastructure. Worked with Python, Node.js, and Java to connect services, designed databases, and set up deployment pipelines with Docker and K3s. Configured load balancers to keep everything running smoothly as traffic scaled.

Pivot Access (Kigali, 2024 - 2025)
Focused on observability—making sure systems are actually visible when running. Set up monitoring with Grafana, Loki, Tempo, and Prometheus, built custom integrations, and designed dashboards so teams could spot problems before users did.

Umurava (Kigali, 2023 - 2024)
Full-stack development with Node.js and both MongoDB and PostgreSQL. Built APIs, handled authentication with AWS Cognito, and integrated cloud services such as S3 and Cognito.
