Ryszard Machmudow, independent developer for Android, iOS and the web

Software built with the care of medical technology.

I design and build mobile apps, web applications and websites — for companies, startups and individuals. Software that simply works: fast, secure and easy to change.

What I build

One engineer accountable from first sketch to release — no hand-offs between agencies, no lost context.

  • Mobile apps — Android & iOS

    Native-quality apps for phones and tablets: from MVP to store release and ongoing updates. Offline support, push notifications, secure sign-in and integrations with your existing systems.

  • Web applications

    Custom dashboards, client portals and internal tools that replace spreadsheets and email chains. Clear data models, role-based access and APIs your mobile app can share.

  • Websites you edit yourself

    Fast, search-friendly company websites with a built-in admin panel: change texts, prices, photos and sections in the browser — no developer, no redeploy. Version history lets you undo any change.

Recent work

Hi, I'm Ryszard

Ryszard MachmudowFounder of Machmusoft, co-founder of Exura

I'm an experienced software engineer, and Machmusoft is my one-person company. I've worked on banking apps, apps for large retailers, Uber-style apps and apps that control smart devices — projects where security and reliability aren't up for debate.

No agency, no account managers: you work with me directly. I write the code, I answer the messages, and I'll tell you when something isn't worth building.

Built where software isn't allowed to fail

I also co-build software for healthcare — a field where data is sensitive, mistakes are expensive and every decision has to be traceable. Those habits come with every project, whatever the industry.

  • Privacy by design

    Personal data is collected only when needed, stored carefully and never sent to third parties without reason. GDPR is a starting point, not an afterthought.

  • Security as a default

    Hashed passwords, rate-limited logins, CSRF protection, strict content-security policies and stripped photo metadata. Standard on every project, not an upsell.

  • Quality you can verify

    Automated tests, clear documentation and a written record of decisions, so the next developer — or an auditor — can see why things are the way they are.

  • Thinking in users, not features

    Healthcare teaches you that real people use software under real pressure. Interfaces are kept calm, legible and accessible.
