I work on SaaS backends, APIs, and system integrations. My experience also covers background processing, automation, and running applications in production.
A product of my own, business integrations, and processing infrastructure.
A product I’m building to help people check their email-domain configuration and understand what the results mean.
Project focus: SPF, DKIM, DMARC, domain diagnostics, and useful explanations of technical findings.
The public tools cover email authentication and domain diagnostics, including SPF, DKIM and DMARC. The challenge is turning protocol-level findings into explanations people can act on. Explore MXFend ↗
Integration work connecting an e-commerce platform with an ERP, including order data and the surrounding business workflow.
Project focus: Python / Django, API adapters, data mapping, background jobs, and operational diagnostics.
Separate platform adapters keep API-specific logic away from the business workflow. Explicit data mapping and background jobs make the integration easier to inspect, test and troubleshoot. The current stage is pilot integration and testing.
Work on a media-processing system with job APIs, worker queues, storage integration, and video encoding.
Project focus: Processing workflows, worker configuration, encoder validation, and deployment infrastructure.
My work includes worker configuration, storage integration and encoder validation. The system is in development; I’m currently working through encoder validation and the behaviour of the processing workflow.
I’m a backend developer based in Czechia. My main focus is Python and Django, with experience in PHP, Vue/Nuxt, and the infrastructure around web applications.
I work across application development, APIs, integrations, and production troubleshooting. My approach is to understand the problem, make implementation decisions clear, and verify how the solution behaves.
I work on the application and the connections around it — APIs, background processing, and the systems that keep it running.
Translate product requirements into Django applications, clear data models and REST APIs that fit the workflows behind your SaaS.
Connect business systems, translate data between APIs, process webhooks and move time-consuming work into background jobs.
Investigate issues across the application stack, work on Docker environments and CI/CD, and make failures easier to diagnose.
I’m interested in long-term, remote B2B collaboration with SaaS teams. I invoice through my Czech business and work on an hourly basis, with a maximum capacity of 120 hours per month.
I work independently and keep collaboration async-first. Meetings and overlap are agreed around the work; my schedule is flexible, without fixed eight-hour daily shifts.
Your product, the backend challenge, and the kind of collaboration you have in mind.
