I have been working as a web app developer for more than 25 years and an iOS developer for almost 15. I love solving problems and making interfaces that people love to use. I've spent years working on, in and around user interfaces, learning what makes a good interface and what makes one great.
Great design is a passion, and I translate that into code every day. I appreciate excellent communication. Whether you need some advice, help with planning, an extra hand with design or development or someone to tackle a project from start to finish, I can help you get where you want to go.
I have developed software for dozens of individual multi-million dollar clients as well as launched two successful startups and a service agency. Building things is my passion, and I love helping clients bring their vision to life.
Outside of development, I love hiking, rafting, movies and travel.

I'm a seasoned software developer with over 10 years of experience in programming. I want to help you with my knowledge to implement interesting projects.
Why you should consider hiring me:
- I have a degree in computer science, over 5 years of professional experience as a developer, and the motivation to still learn new things.
- I have worked on large projects where it was important to work with existing code and work well as a team.
- I have worked on small projects where it was important to find out the requirements of the client and build their idea from the ground up.
- I have the motivation to make every project a success. And that with high quality, so that you get a stable and lasting product.

Your developer vanished mid-project, a critical feature won't ship, or you need AI genuinely built into your product — those are the jobs I take. I'm a senior full-stack and AI engineer who steps into stalled, broken, or half-finished projects and gets them shipping again, fast.
I've shipped 15+ production web and mobile apps end to end — from the database to the deploy — including published iOS apps and SEO platforms serving tens of thousands of pages. I run my own infrastructure (Docker, CI/CD, PostgreSQL), so I diagnose across the whole stack instead of only the piece I'm handed.
What I do best:
Rescue and takeover: inherit a messy or abandoned codebase, stabilize it, ship the next thing
Full-stack build: Next.js, React, TypeScript, FastAPI/Python, Node.js, PostgreSQL, Supabase
AI integration: LLM-powered features, AI agents, and chatbots wired into real products
Payments and automation: Stripe, webhooks, and workflow automation with n8n
iOS: native Swift apps through App Store release
How I work: I move fast, explain things in plain language, and verify what I ship instead of hoping it runs. I've built and run my own products, so I think like an owner — I care whether the thing actually solves your problem, not just whether the ticket closes. Based in Hawaii, I overlap US working hours (especially the West Coast) and keep async projects moving around the clock.
If something's on fire or stuck, send me the details and I'll tell you honestly how I'd approach it and how long it'll take.

I'm a versatile developer and designer specializing in web development, graphic design, and Java/JavaFX applications. I help clients bring their ideas to life through clean, functional websites, visually compelling designs, and well-structured software solutions, using tools like HTML, CSS, JavaScript, React, and Figma to create modern, user-friendly interfaces alongside polished branding and visual content. I'm currently a software engineering student, which keeps me sharp on the latest tools, technologies, and best practices in the field, and I take a detail-oriented approach to every project, focusing on quality, clear communication, and delivering work that meets and exceeds client expectations. Whether you need a complete website, a standout design, or a custom Java application, I'm committed to turning your vision into reality, on time and within budget.

I've spent 13 years shipping iOS and web products in small teams — usually as the person who takes something from architecture all the way to the App Store alone.
Two things I do that most developers don't:
APPLE'S HARD CORNERS
The Screen Time stack (FamilyControls / ManagedSettings / DeviceActivity) and the MDM protocol — the places where the official docs run out and teams lose a month. I've shipped both to production: DeviceActivityMonitor extension memory budgets and the silent kills they cause, opaque ApplicationToken serialization across process boundaries, persistent restrictions that no system cleanup will ever undo, DEP/ADE zero-touch enrollment, APNs HTTP/2, full certificate-chain automation, and a Jamf-to-self-hosted migration.
AI CODING AGENTS ON REAL CODEBASES
I shipped a production iOS app with Claude Code as the primary implementation path — not autocomplete, not a demo. The hard part was never the model. It's knowing which modules are safe to delegate, encoding the conventions nobody ever wrote down, and being able to tell when the output is confidently wrong. Custom skills, hooks and subagents built around an actual Swift / Tuist / Fastlane codebase.
Underneath both: 13 years of React and TypeScript (Tanstack, Jotai, Tauri desktop) and Deno/Hono backends.
HOW I WORK
Written-first and async. Requirements go in a form, decisions go in a document, delivery comes with a recorded walkthrough. I don't need standing meetings and I won't waste yours. I scope tightly, I ship, and I'll tell you when the premise of a request is wrong rather than build the wrong thing well.
WELL-SCOPED WORK I TAKE ON
- Screen Time / parental control / device management on iOS
- Apple MDM: enrollment, APNs, certificate chains, Jamf migration
- Landing AI coding agents in an existing codebase and CI
- Full-stack delivery for small teams

I help startups and small businesses get rid of repetitive work, connect their tools, and actually use AI in a way that makes day-to-day operations easier—not more complicated. My goal is simple: build systems that save time, cut costs, and make your product or workflow feel smarter and smoother.
I’m a Senior AI Automation Engineer and Mobile Developer, and I usually work on projects end-to-end. That means I don’t just write a script or build a small feature—I help you figure out what should be automated, design the system, build it, and make sure it runs reliably in production.
Here’s what I typically work on:
• AI agents that handle tasks and workflows automatically
• Automating business processes (ops, admin, internal tools)
• Integrating LLMs like OpenAI into real products
• Building custom AI features and AI-powered apps
• RAG systems and knowledge-based assistants
• Chatbots for support, sales, or internal use
• Automating CRM, email, marketing, and sales workflows
• API integrations and connecting different platforms together
• Backend systems and cloud-based automation setups
• Mobile app development for iOS and Android
• Cross-platform apps using Flutter or React Native
• Mobile apps with built-in AI features
I care a lot about building things that are actually usable in real life—not over-engineered, not fragile, and not confusing to maintain. Clean architecture, stable performance, and clear communication matter to me just as much as the code itself.
If you’re trying to automate something in your business, build a mobile app, or add AI into an existing product, I can help you figure out the simplest and most effective way to make it happen—and then build it with you end to end.
