Engineering leadership
A Director of Engineering seat, on contract — running delivery, technical direction and the standards a team is held to, for companies not yet ready for the permanent hire.
Software engineering · Cloud · AI
We design, build and run software that has to work.
Yodly provides engineering leadership to B2B SaaS companies, and builds production software. We take on a small number of engagements at a time — and we do not recommend anything we have not had to run ourselves.
Capabilities
Senior engineering, end to end
We take a small number of engagements at a time, and stay in them. Long-running relationships rather than one-off deliveries.
Product engineering
Backend services, web and native mobile clients, data pipelines and the release machinery around them — owned from first commit to running under real load.
Cloud-native platforms
Event-driven and serverless systems on AWS, defined as infrastructure-as-code, with autoscaling, multi-AZ resilience, observability and cost control built in rather than retrofitted.
AI engineering
LLM-backed features built to production standards — retrieval, tool use and evaluation harnesses — plus AI-assisted delivery, which is why a team this size ships at this rate.
Architecture & advisory
Deciding the expensive things early: service boundaries, data model, cloud topology, and migration paths a team can execute incrementally without a big-bang cutover.
Work
Selected work
Two production platforms we designed, delivered and still operate. The shortest answer to what our work looks like.
Wylo
A fitness and nutrition platform for studios and their members — training programmes, meal planning, memberships and payments, with native mobile clients.
wylo.ro ↗Sterodata
A data platform for collecting, structuring and querying large volumes of operational data, with an emphasis on making that data usable rather than merely stored.

Built the way we build for ourselves
- We build things we then have to run
- Wylo and Sterodata are systems we designed, built and still operate. Client work is held to the same standard, because it is the standard we have to live with ourselves.
- Production from day one
- Deployment, monitoring and rollback exist before the first feature does. It costs a week early and saves months later.
- Boring infrastructure
- Managed cloud services, infrastructure as code, and the smallest number of moving parts that satisfies the requirement.
- You own the result
- Source, infrastructure definitions and accounts are yours. We write things down so the work survives us leaving.
