She took our ideas and made them better.
Who this is for
This might be you.
You're in a high-stakes, regulated market.
Orange County industries — MedTech, FinTech, Real Estate — run on compliance, precision, and reliability. Your software needs to match the standards of the market you're competing in and selling to.
Your data is fragmented.
Multiple platforms, manual exports, a spreadsheet someone emails every Friday. The system holds together because your team makes it work. That's not sustainable at the scale you're growing into.
You want a nearby partner, not a black box.
Not an offshore team where you never talk to the engineer. You want a senior developer who can be in your Irvine or Newport Beach office when the real decisions need to get made.

The approach
How I work with Orange County clients.
I come to your office.
OC clients get an on-site discovery session before any scoping begins. Whether you're in Irvine, Newport Beach, Costa Mesa, or South County — I drive to you first.
Architecture before code.
Before a line is written, we agree on what we're building. What's decided in design is a conversation. What's decided mid-build is expensive.
Visible progress at every milestone.
You see what was built at each phase, give feedback, and we move forward with shared context. No surprises, no disappearing acts.

End-to-end, every time.
Every engagement covers the full scope — from architecture to handoff.

Common questions
Before you reach out.
Do you travel to Orange County client offices?
Yes. Most OC offices are under 45 minutes from my base. I travel to Irvine, Newport Beach, Costa Mesa, Anaheim, and across South County for discovery sessions and working meetings.
Do you work with MedTech or healthcare companies in OC?
Yes. I build HIPAA-ready systems — patient portals, intake workflows, reporting dashboards, and EHR integrations. Healthcare software requires careful architecture, and I've built for it before.
Can you help with compliance-heavy industries like FinTech or Real Estate?
Yes. Compliance isn't something I add at the end — it's part of the data model and architecture from the start. CCPA, HIPAA, and SOC 2-aligned practices are built into how I design systems.
Are you familiar with the Irvine enterprise tech corridor?
Yes. Orange County has a dense cluster of serious B2B software companies. I understand the buyer expectations, technical maturity, and procurement patterns that come with that market.
Can we schedule an in-person meeting in OC before committing to anything?
Absolutely. A 30-minute in-person meeting in Irvine or Newport Beach to talk through your situation costs nothing. That's often the most useful first step.
