I have worked at the intersection of creativity and technology throughout my career, designing and programming animations and interactivity for ads, websites, web apps, games, emails, and presentations. As a Senior Motion Developer at Publicis, I built dynamic interactive animations and organized workshops with industry leaders to enhance my team’s skills. At Atmosphere Proximity, I led the transition of over 200 animated ads from Flash to HTML5 in three months as the technology was emerging. At KBS, I built a range of digital experiences for BMW, including an animated application for new BMW owners. As a motion designer at R/GA, I created page transitions, interactive prototypes, animated doll features, and splash screens for Hasbro’s Lorifina fashion doll website. I also developed whimsical dragon character animations and an immersive aerial map zoom effect for the opening and closing sequences of "The Search for Dragon Island" online game, an interactive experience inspired by the film How toTrain Your Dragon 3D. During my time at Atmosphere BBDO, I created cutting-edge mini games for an award-winning Snickers campaign. I started my career working in Flash and ActionScript and as the industry shifted, I smoothly transitioned to HTML5, CSS, JavaScript, and GSAP for animations and interactivity. Overseeing the transition of hundreds of ads at Atmosphere Proximity was a key part of that evolution, ensuring interactive experiences remained accessible as Flash became obsolete. That adaptability has been a constant in my career—I enjoy learning new technologies and finding innovative ways to bring designs to life. Currently, I’m expanding my skills in React and After Effects to bring more flexibility to my work. I’d love the opportunity to contribute my animation skills and creative problem-solving abilities to your project while continuing to grow as an animator, developer, and designer. Thank you for your time and consideration. I look forward to the possibility of speaking further.

I'm a seasoned programmer and developer who has been in the IT field since the mid-eighties. I owned and operated a software development business in the nineties and have been a web developer since the mid-nineties. My skills include PHP, SQL, HTML, CSS, Javascript, JSON, BASIC, Delphi (Pascal), C/C++, and XML. My preference is core languages as opposed to frameworks. However, I have been exposed to a few PHP and Javascript frameworks and I am a quick study. I am proficient at back-end web development, relational database development, API integration via RESTful services, web content scraping (PHP, jQuery), pattern matching via regular expressions, OOP, ETL, MVC, and general problem solving. Some of the vocations in which I have worked as either a programmer analyst or web developer include government agencies, educational institutions, e-commerce businesses, general retail companies, and a variety of others. I enjoy a challenge and being able to problem-solve. When I take on a project or task, I see it to completion. I write clean code and believe in good documentation. Give me a try for your project needs within my realm of expertise - you won't be disappointed.

The Quick and Dirty Version: I’m an App Store veteran with 10+ years of experience building polished, scalable iOS apps — with hundreds of thousands of users across live products. I can take your app from idea to launch, or plug in wherever you need help most. The Longer Version: I'm a seasoned iOS developer and solopreneur with over 15 years of programming experience — and more than a decade of building and shipping apps on the App Store. My apps have earned hundreds of thousands of downloads, and I currently have multiple live apps with two more launching soon. I’m local to the NY/NJ area, which means I’m not just another anonymous profile — I’m someone you can actually reach, talk to, and rely on. As a one-person operation, you get direct communication, fast responses, and someone who’s fully committed to your project’s success. I can take your app from concept to launch, or jump in anywhere along the way — whatever you need. I’ve worked across the full development stack: ✅ UI/UX Design ✅ In-App Payments ✅ Firebase & Custom Backend Integration ✅ Real-Time Sync & Performance Optimization ✅ Subscriptions & IAP Monetization ✅ App Store Submission & Ongoing Support I’m new to this platform, but not new to mobile development. I’m here to build long-term client relationships, and I’m willing to go above and beyond to earn your trust as I grow my profile on Upwork. If you're looking for a developer who’s not only experienced, but genuinely cares about quality and outcomes — let's talk. I’m ready to help bring your app idea to life.

My professional career started out with freelance consulting while attending college and learning to program. I was then given an opportunity to join an early-stage health tech startup as a technical co-founder and employee #1. Over the last decade I created and launched multiple products with varying levels of success. One of the products that I developed was successful enough to be awarded a US Patent and ultimately led to our company getting acquired. I'm interested in exploring new opportunities to expand my knowledge and work on solving interesting problems with individuals that are easy to work with.
