solution first, empowered by technology.
Custom Software
Your business runs on workarounds, spreadsheets, or tools that don't quite fit.
I design and build tailored applications that solve your specific bottleneck. Full-stack, scalable, no bloat.
Legacy Transformation
Your software works, but it's slow, fragile, and expensive to change.
I refactor and modernize existing systems into maintainable assets. No need to start from scratch.
Process Automation
Your team spends hours on tasks a machine should handle.
I identify manual workflows and replace them with automated solutions that run reliably in the background.
Technical Consulting
You need technical leadership, but not a full-time hire.
I act as a fractional CTO, bridging the gap between your business goals and the technical execution.
System Integration
Your tools don't talk to each other. Data lives in silos.
I connect your software ecosystems through clean APIs and integrations. One source of truth, no manual syncing.
Data & Analytics
You have data, but no answers. Decisions are based on gut feeling instead of evidence.
I build pipelines, dashboards, and reporting systems that turn raw data into actionable insights. Measure what matters.
Sounds like something you need?
HOW I WORK
We talk
You describe the goal. I listen, ask the right questions, and figure out what actually needs to happen.
I build
I leverage AI-augmented development to move fast without cutting corners. What used to take weeks now takes days. You stay in the loop without micromanaging.
You ship
You get a working solution, not a prototype. Documented, deployable, and built to last.
