Available for new work

I build the software, and I run the systems it sits on.

Ten years of shipping web applications, and the same ten years spent administering the servers, domains and mail systems behind them. For a small company that means one person to call, whether the problem is a bug in your platform or an email migration that has to happen without losing a message.

I work with US clients from Manila, with my hours arranged so that cutovers and remote sessions land overnight for you and cause no downtime in your working day.

What I do

Software development

Full-stack work on applications people use every day, new builds and inherited codebases alike.

  • React · TypeScript · Next.js
  • PHP · Laravel · WordPress
  • C# · .NET · Azure
  • Supabase · MySQL · PostgreSQL

Email and account migrations

Moving a company between Google Workspace and Microsoft 365 without losing mail, calendars or the logins that depend on them.

  • Microsoft 365 tenant setup
  • Mail, calendar, contacts, files
  • DNS, SPF, DKIM, DMARC
  • Laptop setup and handover

Automation and AI integration

Removing the manual steps between the systems you already pay for.

  • n8n · Logic Apps · webhooks
  • OpenAI and Claude APIs
  • Reporting and analytics
  • Scheduled jobs and alerting
Selected work
A migration, concretely

What actually changes on cutover night

Most of a migration is preparation. The switch itself comes down to a short list of records, changed in an order that keeps mail flowing the whole way through. This is the shape of it for a company moving from Google Workspace to Microsoft 365.

DNS records before and after a Google to Microsoft cutover
RecordBeforeAfterWhy it matters
MX aspmx.l.google.com <tenant>.mail.protection.outlook.com Where new mail is delivered
SPF include:_spf.google.com include:spf.protection.outlook.com Changed too early, your sent mail goes to spam
DKIM google._domainkey selector1 / selector2 Signs outgoing mail as genuinely yours
DMARC p=quarantine p=quarantine, reports to you Tells you who is sending as your domain
Autodiscover autodiscover.outlook.com Phones and Outlook find the new mailbox on their own

The part that catches people out isn't in this table: every service you sign into with a "Sign in with Google" button keeps pointing at Google after the move. Those have to be converted first, while the old account still works.

How I work

Three things worth knowing before you hire me

Access, not passwords. I work through delegate invitations and admin accounts in your name. Your credentials stay yours, and you can revoke my access in a click when a project ends.

Your account stays yours. Licences and domains are bought on your card, in your name. Nothing I set up for you is hostage to me still being around.

Work happens outside your business hours. Manila runs twelve hours ahead of New York, which makes your quiet hours my working afternoon. Migrations and reboots happen while your team is asleep.

Contact

Tell me what's breaking, or what you want built

A couple of sentences is plenty to start. I reply within one business day, and I'll tell you honestly if it isn't something I should take on.
