What I can build for you

If it's on this list, I've already built it for a real business. I can show you it working before you spend a dollar. Tap any card to see what it means for you.

Admin dashboardsYour whole business on one screen: sales, customers, appointments, and what needs attention today. You stop guessing and start deciding from live numbers, without juggling five different apps.
Automated email confirmations and remindersConfirmations, reminders, and follow-ups that send themselves by email, in the customer's language. Set up once, never forgotten.
Bilingual and trilingual sitesYour entire site, forms, and emails in English, Spanish, and French — switchable with one tap, written properly in each language. Customers buy more when they're spoken to in their own language, and most of your competitors only speak one.
Booking and reservation sitesCustomers pick their time and book themselves, day or night, with deposits collected up front. No back-and-forth messages, no double bookings, and far fewer no-shows.
Commission and referral trackingPartners and reps get their own tracked codes, every sale is credited to whoever brought it, and payouts become simple math instead of arguments.
Customer tracking pipelinesEvery inquiry becomes a card that moves stage by stage from first contact to paid, so you can see your whole funnel and its value at a glance. Nobody gets forgotten, and the next follow-up is always obvious.
Eco-friendly, right-sized hostingYour app runs on machines sized to your real traffic instead of a bloated hosting package. That means lower bills, less wasted energy, and room to scale up the day you actually need it.
Interactive mapsYour locations on a live map customers can explore — find the nearest spot, tap for details, get directions. Works beautifully on phones.
Light and dark modeEvery app can ship with a light and a dark look, switched with one tap. Customers read comfortably by day or night — try it on any of my live sites below.
Live demos with sample dataA try-it-yourself demo of your product, filled with invented sample people and resetting itself automatically. Prospects convince themselves before they ever message you.
Membership programsPaid memberships with logins, perks, and automatic renewals. Recurring revenue you can count on every month, and customers with a reason to keep coming back to you instead of shopping around.
Online forms and e-signaturesPaperwork becomes a link: customers fill everything out on their phone and sign with a fingertip before they ever walk in. Nothing gets lost, nothing is illegible, and it's all stored safely.
Payment and subscription systemsTake cards, deposits, and recurring subscriptions online, the moment someone decides to buy. Money arrives while the excitement is high, and renewals bill themselves without you chasing anyone.
QR codes and redemptionPrintable QR codes customers scan to redeem deals or check in, validated live so a code can't be reused or faked. Perfect for passes, events, and promos.
Qualification quizzesA short quiz that sorts serious buyers from window-shoppers before they reach you. Your time goes only to people who qualify.
Secure handling of private dataSensitive customer information is encrypted, access-controlled, and backed up automatically every day. Your customers can trust you with their details, and a stolen file would be unreadable gibberish.
Voice notes and speech-to-textCustomers talk instead of type, and their recordings become clean text automatically. Less friction for them, readable records for you.
WhatsApp notifications and automationsYour business talks where your customers already live: instant WhatsApp alerts to you when a lead arrives, and confirmations and reminders to them. WhatsApp messages actually get read — email mostly doesn't.
White-label versionsAny app I build can launch entirely under your brand — your name, your logo, your colors on every screen. Nobody ever sees mine.

Medical-tourism clinics lose patients the same way every time: someone asked a question from abroad and nobody followed up. My Custom Dental & Medical Office CRM is WhatsApp-based — every inquiry is caught and walked, visibly, from first message to booked appointment, and because it lives where international patients already are, reminders and follow-ups can be automated. Open the demo and see it in ten seconds.

  • No patient inquiry ever falls through the cracks
  • WhatsApp-based, so reminders and follow-ups can be automated
  • The whole team sees every patient's status at a glance
  • Built for international patients: English, Spanish, French — nothing to install
  • Light and dark mode — try the toggle on the live site

Multi-tenant SaaS with strict tenant isolation, WhatsApp-first patient communication, a 900-line trilingual medical intake with canvas e-signature, an hourly self-resetting live demo, and CSV formula-injection protection. Built in roughly ten days.

Turns "just looking" visitors into qualified patients. A two-minute quiz sorts real candidates from browsers, medical paperwork gets signed from a phone before anyone travels, and the clinic sees an organized pipeline instead of a pile of chats. The two-minute quiz is public — try it yourself below.

  • Leads arrive pre-qualified by the quiz instead of cold
  • Medical paperwork is signed online before the patient travels
  • Patient data stays encrypted and organized in one place

Custom Multi-Business CRM

The demo entry page A contact card — sample data, not real people
White-label option: your name, your logo, your colors

All your businesses, one screen. Every customer, deal, and booking in its lane under a single login. And if the database were ever stolen, the sensitive parts read as gibberish, because they're encrypted. The demo is open: sample data, resets itself hourly.

  • All your businesses managed from one login, data never mixes
  • Two businesses included free — add more as you grow
  • A stolen database leaks nothing, sensitive fields are encrypted
  • Every change is logged with who made it, backups run themselves
  • Light and dark mode — try the toggle on the live site

Field-level AES-256-GCM encryption for 30 sensitive fields with zero-downtime key rotation, per-actor audit logging, JWT auth with instant revocation, and off-site S3 backups. Held up under a six-agent adversarial security audit.

One hire, a whole team's job

Most projects need a designer, a copywriter, a developer, and someone to keep it running after launch. Here, that is all the same hire.

How it works

One person, start to finish. No account managers, no hand-offs.

1

Tell me what you need

What's missing, what's eating your time, what you wish ran itself.

2

Get a clear plan

You'll know what it takes, what it costs, and when it can be live — before you commit to anything.

3

Watch it go live

Built, deployed, and kept running, with a direct line to me.

Most people hiring a developer are really buying a promise. A proposal, some mockups, a portfolio of screenshots, and then you pay and hope. I removed the hoping. Everything on my page is a live product you can open right now, on your phone, before we ever speak. Click the demos, log in, poke around. If my work doesn't convince you in five minutes, close the tab and you've lost nothing. That's the deal, and nobody else is offering it to you, because almost nobody else can.

When you work with me, the person you message is the person who builds it. There's no account manager relaying your words to a designer who relays them to a coder overseas. You tell me what your business needs, in plain language, and the same brain that heard you writes the copy, designs the screens, builds the system, launches it, and answers you afterward. Nothing gets lost in handoffs because there are no handoffs.

And I don't just build apps, I run them. My own systems take real payments, manage real customers, hold encrypted medical records, and send real bookings every day, in three languages, for real businesses. That changes what I build for you. Someone who has never operated an app builds what looks good in a demo. I build what survives contact with actual customers, because I'm the one who gets the message when something breaks at 11pm on my own products. Every lesson those apps taught me is already baked into yours on day one.

Everything ships white-label: your name, your logo, your business on every screen. Your customers see your company, not mine. And because I work lean, no office, no team of ten billing hours, no bloated servers, you get agency-level product at a fraction of agency cost and agency speed.

So here's why you'd prefer me, in one sentence: everyone else asks you to trust them, and I ask you to try me first.

Skills

The stack behind everything above.

Everything above is production, not portfolio theater. Real Stripe subscriptions with webhook reconciliation, multi-tenant auth, encrypted health records, trilingual interfaces, automated backups that get restore-tested. One person designed, built, deployed, and operates all of it, which means no requirements lost between a PM, a designer, and a contractor. You're reading the work of the same brain you'd be messaging.

The infrastructure tells you the rest: right-sized machines, boring proven stack, nothing over-provisioned. Systems built by someone who pays the hosting bill and gets the message when their own product breaks get built differently, and you can inspect the difference yourself right now.

Don't take my word for any of it. Open the demos and try to break something.

You'll get a straight answer about what it takes, what it costs, and when it can be live.
