Senior Cloud & Backend Engineer
Python / AWS
I design and build reliable cloud-native backends, data pipelines, and integrations — from proof of concept to production.
Hi, I'm Petr Mašek — a senior backend and cloud engineer with 20+ years of software development experience and 5+ years focused on Python and AWS.
I specialize in designing and implementing cloud-native systems built around AWS Lambda, Step Functions, event-driven architectures, and data processing pipelines.
I'm used to working in international teams, communicating in English on a daily basis, and delivering production-ready solutions for enterprise environments.
Design and implementation of scalable backends using AWS Lambda, Step Functions, S3, DynamoDB / RDS, OpenSearch, and event-driven patterns.
Processing large JSON datasets, building validation pipelines, integrating third-party systems, and exporting structured outputs.
Rapid prototyping and focused backend projects where clarity and speed matter.
Background in Java backends, Kubernetes tooling, and long-running enterprise systems.
I prefer clear ownership, pragmatic communication, and technically sound solutions. I'm comfortable working independently or as part of a distributed team, and I value projects where engineering quality and reliability matter.
