Custom software for Los Angeles businesses.
Custom software development for Los Angeles businesses and remote teams across North America.
She took our ideas and made them better.
Who this is for
This might be you.
You've outgrown off-the-shelf.
Your Los Angeles business has hit the ceiling of what Salesforce, Airtable, or a pile of connected SaaS tools can do. What you need isn't another subscription — it's a system built around how you actually operate.
Your systems are held together by the right people.
There's someone on your team who just knows how things work — the shortcuts, the workarounds, the 'just ask me' situations. That's not a system. That's a single point of failure.
You want someone local, not a queue.
Not another offshore team or an agency where you never talk to the engineer. You want a senior developer who shows up, understands the business, and builds it right.

The approach
How I work with Los Angeles clients.
On-site discovery, first.
I want to see how the business runs before scoping anything. For LA clients, that means coming to your office — Culver City, DTLA, Long Beach, or the Valley — and mapping the real friction before any design begins.
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.

Common questions
Before you reach out.
What areas of Los Angeles do you serve?
All of greater LA — Silicon Beach, the Westside, DTLA, Pasadena, Long Beach, the San Gabriel Valley, and beyond. On-site discovery is available throughout the metro.
Can we meet in person in Los Angeles?
Yes. I build in-person discovery sessions into every LA engagement. We can meet at your office, a co-working space, or wherever works for your team.
Are your systems CCPA-compliant?
Yes. California Consumer Privacy Act compliance is part of the data architecture from the start — not bolted on after. User consent, access controls, and data deletion workflows are built in.
What industries do you work with in LA?
Legal and consulting, entertainment-adjacent tech, health and wellness, e-commerce, and nonprofit. If you're running a business system that needs to scale, I probably know your operational context.
How much does custom software development cost?
Most engagements run between $10,000 and $50,000. Complexity, integrations, and timeline affect the final number. A discovery conversation is always free — that's where we figure out the actual scope.
