about
One senior developer. One point of contact. Software that ships.
I'm Abigail Castellon, the developer behind AbbaCodabra. I build full-stack applications and AI-powered products from concept to deployment. No middlemen. No handoffs. Just fast, high-quality execution.
cat about.md
As a full-stack developer and AI engineer, I help businesses transform ideas into reliable, production-ready software. Based in Staten Island, NY, I also serve clients in Phoenix, AZ, Clark, NJ, and worldwide.
Combining experience in investment and international finance with modern software engineering, I create technology solutions that turn complex ideas into reliable products. My expertise spans full-stack development, AI applications, blockchain technology, automation systems, trading platforms, and custom software across web, desktop, and emerging technologies. Every solution is built with scalability, performance, and precision in mind.
I work in English and Spanish — briefs, calls, documentation, and the software itself. If your team or your customers are bilingual, so is what I build for you.
With a 5.0-star rating, 100% on-time delivery, and 100% on-budget completion, I believe great software starts with understanding your goals. Your project isn't just another job — it's a partnership, and its success is my priority.
principles
01
Ship, don't stall
Small cycles, working previews, steady progress — you watch it come together instead of waiting on a silent black box.
02
You own everything
Clean, documented code in your repo, on your accounts. No lock-in, no hostage situations, no mystery.
03
Talk like a human
Plain-English updates, honest trade-offs, no jargon smokescreen. You always know exactly where things stand.
