As a Senior Cloud Platform Engineer & Architect, I help application teams deploy and run their own services on AWS. I have more than ten years of hands-on AWS experience and have worked as a freelancer on B2B contracts since January 2023. I work directly with developers, testers, operations engineers and delivery managers, taking responsibility for my assignments from the initial investigation through implementation and handover.
I start by tracing how a team takes a change from source code to deployment with the tools it already has. I reuse what works and adapt existing components where they slow developers down. When a new tool is needed, I design it, write the code and roll it out in stages so the team can keep releasing.
I helped a bank's engineers design a new internal developer platform (IDP). To improve developer experience (DevX), I adapted selected components and worked with application teams to simplify their deployment workflows. Later, when slow releases on a mission-critical platform were holding up testing, I shortened deployment times. I ran hands-on workshops so developers from the incoming delivery partner could take over deployments themselves.
I build reusable infrastructure with AWS CloudFormation and CI/CD pipelines with TeamCity. I use CloudWatch metrics to right-size workloads on Amazon ECS and tune autoscaling to balance reliability and cost. Logs and alarms help me trace failures. When several teams run into the same problem, I turn the solution into a shared component, an automated check or a guide they can use themselves.
Python is my main language for automation and backend API development. I designed and built a FastAPI gateway that gives AI tools controlled access to functions in existing software. It exposes selected REST operations and enforces their limits on the server. Its OpenAPI schema describes the operations and their inputs. I wrote documentation for developers and skills for agents so both can use the same interface.
I work with coding agents daily, using tools such as Devin, OpenAI Codex and GitHub Copilot. I review their proposed changes as I would a colleague's pull request, run linters and tests, and verify changes in development before rollout.
Before freelancing, I spent seven years at Infor operating multi-tenant SaaS across multiple AWS regions. I shared on-call duties and handled priority-one incidents with colleagues in the US, Europe and Asia.

Project history
I have worked as a self-employed freelance engineer in the Czech Republic since January 2023. In October 2026 I founded ResBem Evolution s.r.o., a Czech limited liability company. The name stands for Reliable Enterprise Systems, Built for Easy Maintenance and Evolution. I chose to take on the business decisions as well as the engineering. As the "AI CEO" of a one-person company, I get to write the brief and deliver the work myself.
The company grew out of AI GTD, my adaptation of Getting Things Done for work with AI, which I began developing in January 2026. I manage my backlog in Jira and run my own Scrum sprints. I use AI agents to help plan sprints, review commitments, schedule reminders and maintain project knowledge and operating rules in Confluence. I also use this approach to prepare bookkeeping records and track legal obligations.
My operating goals are NoOps for routine work and zero errors. I use AI to build tools that replace repetitive ClickOps and can then run without a model call. I define what agents may do, approve consequential actions and use separate checks to verify what actually ran. I test these workflows against real deadlines in my own company before adapting them for clients. I make the final decisions and take responsibility for the results.
The business requirement was to give AI tools controlled access to functions in existing software. I designed and implemented a gateway in Python with FastAPI. It exposes a defined set of operations. For requests made through the gateway, the API enforces the permitted scope even when an agent disregards its instructions.
I wrote API documentation and agent skills that explain which operations are available and how to call them. Scripts and AI tools can use the same interface. A business can apply this approach to other systems with a programmatic interface and choose which functions to expose.
I began developing the concept in late March 2026, built the first proof of concept in May and brought the gateway into regular use in June. I have continued developing it since then.
I provide ongoing technical support for the online shop of a small fashion design business. I work directly with the designer to resolve technical issues and help her choose, set up and use the tools the shop needs. When she has an idea for a change, I explain the options in plain language so she can decide what fits her business.
Our work together now includes AI adoption. We pick a task from her working day and try an AI tool together so she can judge its usefulness for herself.
I learn from the questions she asks. They show me what is clear to someone whose expertise is outside IT and where an example from the shop makes a technical idea easier to understand. I use the same skill in larger organizations, discussing the impact of a change with business teams and its implementation with engineers.
