Minimum Viable Product (MVP) and rapid software prototype development

Ship your mobile, desktop, embedded or web project with a senior engineer who's done it before.

I'm Sean Ashton, the engineer behind Schimera. I build full-stack solutions across mobile, embedded, desktop and web — and I specialise in Chainway mobile computers, RFID, NFC, and barcode scanning for high-volume systems like warehousing, logistics and asset tracking.

Whether you need a complete product built or an expert to unblock your team, you work directly with me — no agency layers, no hand-offs.

MVP and Rapid Software Development

I help startups and growing businesses bring their ideas to life through fast, cost-effective Minimum Viable Products (MVPs) and software prototypes.

Mobile software development

I design and build scalable, maintainable mobile solutions, ensuring consistent user experiences across platforms.

I focus on creating applications that clients can manage and update with minimal ongoing developer involvement, supporting long‑term reliability and growth.

Web development

I build fast, reliable web applications using Python/Django, Rust, Tailwind CSS, JavaScript, Alpine.js, and htmx. A system you can actually run yourself: update content, publish pages, manage forms, make changes — without opening a support ticket every time something small needs to move.
