We build software that
runs real businesses
SDS is a software studio. We ship our own SaaS products — like TallyTill — and design, build, and integrate custom .NET, Azure, and AI systems for clients who need senior engineering, not a committee.
TallyTill — checkout without the checkout
You grew it. Get paid for it.
An autonomous, computer-vision checkout for micro-retail. One ordinary camera turns a farm stand, honor-system market, or lobby kiosk into a self-checkout — the AI recognizes items and customers pay by QR or card. No cashier, no card reader, no new hardware.
- Retrofits the displays you already own
- On-device AI recognition, offline-first, cloud-synced
- QR & card payments — a real multi-tenant SaaS platform
A product company that also builds yours
Two ways we work — and each makes the other sharper.
Products
We build and operate our own SaaS — so we ship production software, not slide decks.
- TallyTill — autonomous computer-vision checkout (flagship)
- Yoga Flows — AI-assisted 3D fitness app on Google Play
- Multi-tenant architecture, payments, AI, offline sync — in production
Consulting & Integrations
Senior engineering for hire — custom apps, cloud architecture, AI, and systems integration.
- .NET / C# apps, APIs & legacy modernization
- Azure architecture, DevOps & Bicep IaC
- AI & LLM integration (Claude, OpenAI, MCP, agents)
- Integrations — payments, identity, and third-party APIs
- Full-stack web — Angular / React on .NET

A boutique studio means you work directly with the person doing the work.
Roy Lawson
SDS is led by Roy Lawson — a senior software architect and full-stack .NET developer with 25+ years delivering enterprise-grade systems across insurance, healthcare, government, finance, and retail. Over the past year that expertise has gone deep on AI: integrating large language models into .NET applications, building agent systems with the Claude Agent SDK, and using AI-assisted development to ship faster without sacrificing quality. No account managers, no ticket hand-offs — direct access to the engineer.
