Software consulting
Engineering teams that ship, software that lasts.

Services
How I can help
Focused, senior-level support for the technical side of your business, scoped to what you actually need.
Software architecture
Designing systems that fit the problem, with clear boundaries, sensible trade-offs and room to evolve without rewrites.
Custom software development
Hands-on design and development of web applications, APIs and integrations, delivered with maintainability in mind.
Delivery & engineering process
Practical planning, code review and release practices that help teams deliver predictably without heavy ceremony.
Cloud & DevOps
Cloud infrastructure, CI/CD pipelines and operational tooling that keep environments reliable, observable and cost-aware.
Technical advisory
An experienced sounding board for founders and leadership: technology strategy, vendor choices and technical due diligence.
Approach
Simple, transparent engagements
Every engagement starts with understanding the problem, not selling a solution.
Understand
A conversation about your goals, your team and the constraints you are working within.
Plan
A clear, scoped proposal with the outcomes, timeline and way of working agreed upfront.
Deliver
Hands-on work with regular check-ins, so progress is visible and priorities can shift as you learn.
Hand over
Documentation and knowledge transfer so your team owns the result long after the engagement ends.
