About me

Built by an operator,
not just a developer.

Most automation freelancers have built demos. I've run the systems I build — inside real companies, at real scale, where failure isn't an option.

The story

I learned this work inside the operations I now build for.

I'm Levy Lester Delos Santos — an AI automation specialist and Airtable developer. I spent 5 years building the operating infrastructure of US companies from the inside: a freight logistics operation, a coaching business, a construction firm, and enterprise teams managing 10,000+ users.

Not as a consultant dropping a deck and leaving — as the person who designed the databases, wired the automations, built the dashboards, led the dev team, and answered for it when something broke at month-end.

That's the difference you feel in my builds. I've sat in the operator's seat. I know which automations save real hours and which just look good in a demo — because I've run both.

For larger projects and ongoing retainers, I also run Crestlyr — an agency with a dedicated team building, planning, and maintaining the systems companies run on, long after launch day.

Why teams pick me

Three things, together, that you won't find apart.

AI-native, not AI-bolted-on

I use Claude and GPT daily, in production. AI is embedded into every system where it earns its keep — drafting, classifying, summarizing, calling — not sprinkled on top for the pitch deck.

Airtable, at expert depth

Not "I've used Airtable" — I build entire company operating systems on it. Multi-table architecture, role-based interfaces, automations, and reporting that whole teams run on daily.

Operator experience

I've led teams, run payroll cycles, and owned month-end. I build for the messy reality of operations — exceptions, edge cases, and the person who'll maintain it after I leave.

How I work

Honest by design

What you can expect from me

  • Scope in writing before any build starts — no verbal promises
  • A weekly one-line status update on every active build
  • Replies within one business day — we don't pretend to be 24/7
  • Documentation and a walkthrough video with every delivery
  • If automation isn't the answer for you, we'll say so in the audit

Where I am

I work remotely from the Philippines with overlap on US, UK, and Australian business hours. That's not a compromise — it's the model: senior-level systems work at 30–50% below Western agency pricing, with builds progressing while your team sleeps.

Every system in my portfolio was built and run in production for a real company — nothing here is a mock-up.

Questions

Things people ask me

Are you an agency or a freelancer?
A freelance specialist — you work directly with me, the person designing and building your system. No account managers, no handoffs to juniors. For team-scale projects, I bring in my agency, Crestlyr.
How do payments work internationally?
Invoices in your currency (USD, GBP, or AUD), paid by Wise or PayPal. 50% to book your build slot, 50% on delivery. Every project runs on a signed contract and scope of work.
What happens after delivery?
Every build ships with documentation, a walkthrough video, and a 7-day support window. After that, most clients either run it themselves (it's built to be maintainable) or keep me on a monthly retainer for optimization and new automations.
Can you work with the tools we already have?
Almost always, yes — that's usually the right call. I build around your existing stack and recommend changes only when a tool is genuinely the bottleneck. If something has an API or a webhook, I can connect it.
