I handle everything in between.
You hired a freelancer who vanished mid-project. You paid an agency that delivered a slow site nobody buys from. You are tired of chasing five different people for one result.
You do not need an agency, a designer, a domain consultant, and a marketer. One person, one timeline, one invoice, covering every layer between your idea and a paying customer.

Uptime
I have been building on the web since I was 13. Most agencies hire someone like me and charge you three times the price.

Numbers, not promises.
Every month without a real platform is revenue you are not collecting.

02 · SERVICES
What I build for you.
A rough idea, a half-finished product, or a broken codebase you inherited. I take it from where it is now to live and earning.
Maybe you already paid someone to build this. Maybe they ghosted you. Maybe what you got back does not work the way you need it to. Start here instead.
Web Applications
Fast, reliable platforms built for real traffic. Page loads under 1 second on a normal connection. Clean code that any developer can pick up after me without a rewrite.
Automation & Bots
Systems that run while you sleep. Discord bots, Telegram bots, web scrapers, internal workflows. If someone on your team does it more than twice a week, I can automate it.
Browser Extensions
Custom Chrome extensions published to the Chrome Web Store. I have shipped 3 of my own already, with active daily users.
API Integrations
Stripe, webhooks, internal tools, third-party APIs. Wired together so nothing falls through the cracks and nobody on your team copy-pastes between dashboards anymore.
Email Systems
Emails that land in inboxes, not spam. Transactional, marketing, welcome flows. Tested across Gmail, Outlook, and Apple Mail before a single customer ever sees them.
Every week you spend duct-taping tools together is a week your competitor ships ahead of you.
03 · END-TO-END
From idea to live product.
I handle everything in between.
Most freelance projects fail in the gaps. The designer hands off to the developer who hands off to the marketer, and nobody owns the final result. You end up paying three times to fix it.
You do not need an agency, a designer, a domain consultant, and a marketer. One person. One timeline. One invoice.
Most agencies charge 3x more and involve 5 different people who have never spoken to each other. This is the opposite of that.
01/ BRAND
Logo & Identity
New logo from scratch or refinement of what you already have. Color tokens, favicon, social cards, share images. Everything your product needs to look credible from day one.
02/ DOMAIN
Your Domain
I find the right domain name, buy it, and configure everything behind the scenes so your site loads fast and stays secure. You own it. I hand you the keys.
03/ EMAIL
Professional Email
A real [email protected] address, configured so your emails never land in spam. Whether you want the premium experience or a leaner budget, I set it up either way.
04/ BUILD
Design & Development
The full product. Designed, built, deployed. The part most freelancers stop at, I treat as the foundation, not the finish line.
05/ GROWTH
Email Marketing
Welcome sequences, broadcast campaigns, audience segmentation. All wired into your product so every signup stays engaged and converts.
06/ OPS
Ongoing Partner
Same builder, same codebase, no re-onboarding. Monthly retainer for monitoring, updates, and new features. A direct line to the person who built it.
Every month your idea sits in a slide deck is a month it is not in front of paying customers.
ONE PERSON · ONE INVOICE · ONE TIMELINE
Stop stitching freelancers together. Get one person who owns the outcome.

Not locked into any stack. If your project needs something different, I will learn it and ship it.
05 · PROCESS
How it works.
You have probably worked with someone who disappeared for two weeks and resurfaced with the wrong thing built. This process exists so that does not happen.
- 00
Discover
We get on a 30 minute call. You explain the idea, I ask the questions most freelancers skip. You get a clear written proposal within 48 hours.
- 00
Plan
Scope, timeline, and price agreed upfront. No hourly billing. No surprise invoices. You know exactly what you are paying for and when it ships.
- 00
Build
I build. You get updates every few days. You can request changes at any point. You always know what is happening and what comes next.
- 00
Ship
Product goes live. I handle deployment, domain, email, the whole launch. You get the keys, and I stay reachable.
07 · FAQ
Questions you probably have.
Depends on scope. A simple web app is typically 2 to 4 weeks. A full SaaS platform with auth, payments, and email is 4 to 8 weeks. You get a clear timeline before we start, and I do not move it without telling you why.
Readytobuildsomethingthatlasts?
Stop stitching freelancers together. One person, one product, done right.
Every month you wait is another month of leads going to a competitor who already has a working site.
I take on a limited number of projects per month so every client gets my full attention. If we are a fit, the sooner you reach out, the sooner we ship.
