Full Stack Developer with 15+ years of experience delivering scalable production platforms. I am not just a coder; I am a technical partner helping B2B enterprises and SaaS founders translate complex requirements into high-performance software. If you are looking for a Full Stack Developer to take ownership of your architecture, security, and deployment, you are in the right place. 🚀 Why Clients Choose Me as their Full Stack Developer: ✅ Business-First Engineering: Unlike a standard Web Developer who just writes code, I focus on your ROI. I build systems that solve business problems, from complex API integrations to custom dashboards. ✅ Symfony & Laravel Expert: I specialize in high-end PHP frameworks (Symfony/Laravel) and modern frontend stacks. ✅ Scalable Architecture: My solutions are built to scale. I handle Database Architecture and DevOps (AWS/Docker) so you don't have to hire a separate Backend Developer. Core Services & Expertise As your dedicated Full Stack Developer, I cover the entire product lifecycle: 1. Enterprise Web Development (Symfony & PHP) I provide robust Full Stack Developer services using PHP 8.4, Laravel, and Symfony. Whether you need a legacy system modernization or a new SaaS platform, I deliver clean, documented code. Backend Developer logic that handles complex data processing. API Development (REST/GraphQL) for mobile and web apps. Node.js integration for real-time features. 2. Modern Frontend & UI (React Developer) I act as a lead React Developer to build responsive, lightning-fast interfaces. React Developer expertise for Single Page Applications (SPA). Front End Developer mastery including HTML5, CSS, and Web Design implementation. Experience integrating with React Native Developer teams to ensure web/mobile parity. 3. E-Commerce & CMS (WordPress Developer) While I specialize in custom software, I also provide high-level WordPress Developer services for enterprise needs. Custom WordPress Developer plugin creation and theme development. WooCommerce and Shopify Developer API integrations. Performance optimization and technical SEO implementation. My "Full Stack Developer" Process When you hire me as your Full Stack Developer, you get a transparent, agile workflow: Discovery: I analyze your needs better than a typical Web Developer, ensuring we pick the right stack (e.g., deciding between a Python Developer approach or a PHP solution). Architecture: I design the database (MySQL/PostgreSQL) and infrastructure. Development: Agile sprints as your Full Stack Developer and React Developer. Deployment: CI/CD pipelines, Docker containers, and AWS setup. Technical Stack & Capabilities To ensure I can serve as a comprehensive Full Stack Developer, I maintain proficiency and familiarity across a wide range of technologies found in modern Web Developer environments: Backend: PHP (Symfony, Laravel), Node.js, Python Developer (Scripting & Scraping integrations). Frontend: React Developer tools, JavaScript, Angular (Maintenance), Web Design principles. Mobile Context: Experience architecting APIs consumed by a Mobile App Developer (iOS/Android) or Flutter Developer. CMS: Enterprise WordPress Developer workflows, Shopify Developer integrations. Infrastructure: AWS, Docker, Linux, Database Design. Case Studies & Results SaaS Platform: Acted as Lead Full Stack Developer for a B2B platform, handling 10k+ daily transactions. Legacy Migration: Replaced an outdated system with a Symfony/React architecture, improving performance by 300%—a result a standard Web Developer rarely achieves. E-Commerce API: Built a custom middleware connecting a WordPress Developer site to an ERP system. Frequently Asked Questions Q: Can you work with my existing team? A: Yes. I often work alongside a dedicated Front End Developer, React Native Developer, or Mobile App Developer. I can also act as a CTO figure for smaller teams. Q: Do you handle design? A: I have strong Web Design skills for UI/UX implementation. If you have a graphic designer, I will implement their vision pixel-perfectly as your Front End Developer. Q: Why choose you over a generic agency? A: An agency assigns you a junior Web Developer. With me, you get a senior Full Stack Developer and React Developer with 15+ years of proven success. Let's Build Your Solution. If you need a Full Stack Developer who understands business, architecture, and code, let's talk. I am ready to bring your project to production.

Hi, I’m Scott — a goofy web developer who’s been doing this since dinosaurs needed websites. I started messing with code as a kid on an Apple IIe and somehow never stopped. I find I work best with laid-back small business owners and non-profits. Clients usually come to me for WordPress tweaks, Shopify oddities, mysterious bugs, full site builds, and even legacy PHP code that’s been running for fifteen years and went bonkers on the latest version of PHP. Other times it might be reviewing their site, creating an email signature, or simply answering technical questions. I enjoy being a mechanic under the hood of a website, grease on my hands and a smudge across my face. Fixing a weird plugin, patching old decayed code, giving the 1’s and 0’s the occasional talking-to, and keeping sites stable, well-tuned, and quietly humming away. Many clients like using me for ongoing, as-needed support. I charge hourly and don’t use retainers. Clients hang around, pinging me when they need help. Some have been doing that for over 10 years. They ping me with tasks, I add them to my queue and we work through them in the order they came in. So nothing slips through the cracks, and everything gets the attention it deserves. My CFO Jack keeps an eye on things too. Being the Chief Furry Officer and a three-legged Chihuahua, his main duties involve seeking scratches, handing out slurps, and getting paid in treats. Drop me a note — the first hour is free. We can chat or schedule a call to bounce around the details and explore what might be involved. From there you can decide if I’m a good fit or if you’d rather go another direction. (BTW — dinosaurs were terrible at passwords. They kept eating the cookies.) --------------------------------------------- # Client Feedback "Scott is not only fun to work with, he knows the in and out of websites, hosting, emails, and if he has not worked with your issue he will be able to research it and help! His patience and professionalism is outstanding. I highly recommend you reach out to Scott and take the time to speak with him. You will be impressed. I have hired Scott numerous times and he always comes through for me! 😊" -- Patt Sendejas - Within Your Space "I’ve worked with Scott remotely since 2010. When I was in Las Vegas for Photoshop World 2013, we met for the first time in person. I’ve always found Scott helpful and responsive to my problems. I appreciate getting timely replies to my emails. I’m happy to recommend Scott to you. Thanks for the great work on my recent urgent PHP project. It is always a pleasure to work with you." -- Connie Taylor, Fathom Publishing "I've worked with Scott for quite some time on a wide variety of coding tasks for my web site and after previously reviewing dozens of applicants, I knew I made the best decision to go with him. His calm demeanor and skillsets encompassing both front and backend programming saved me quite a few times. I'd highly recommend him. His availability and patience could not be matched. You won't go wrong with him. His ethics are top notch and he won't belittle your coding attempts. He's an all around great guy, both as a person as well as a contractor." -- Brian DeMetz --------------------------------------------- # Snapshot Tech & Toolset (Quick Overview): Languages: PHP (3–8), JavaScript (AJAX, jQuery), HTML, CSS, SQL, NoSQL, Python, Bash CMS/Platforms: WordPress, Shopify, Ecwid, custom builds Hosting: cPanel, WHM, ISPConfig, Webmin, SSH, DigitalOcean, AWS Tools & Infrastructure: Docker, N8N, Uptime Kuma, Nextcloud, Sendy, Revive Adserver, Matomo SEO & Speed: Pagespeed, Lighthouse, Moz, Screaming Frog Project Management: Agile/Scrum, Trello, Asana, Clockify, Timedoctor Certifications: - AA Degrees in Programming & Unix (CSN – Dean’s List) - Google’s Foundations of Project Management - Managing Virtual Teams (LinkedIn Learning) - Software Testing & QA (LinkedIn Learning) - IC3-GS3 (Computing, MS Office, Online Basics) - USAF Customer Service Training - BSA Woodbadge Leadership Training

Create leverage. That is what I do. I build high-performance, secure, reliable software that helps founders and businesses launch and scale with confidence. Since 2010, I have helped founders and established companies turn ambitious ideas, messy workflows, and broken systems into serious software products. Obsession with quality, complete transparency, and no hand-holding - that is how I turn software from a development expense into a business asset. I am an excellent fit if: - You are a founder with a product idea and need more than “someone to code it.” I can help you refine the concept, define the right MVP, validate technical assumptions, choose the right architecture, build the first production-ready version, and support you after launch as the product grows. - You are an established business looking to build a new platform, automate operations, replace spreadsheets, improve workflows, modernize legacy software, scale an existing product, or rescue a bad build. I am especially valuable when the project is too important to gamble on cheap execution, unclear ownership, fragile architecture, or developers who only wait for task lists. I have spent 15+ years building software where failure is expensive, across product types, workflows, and industries including SaaS platforms, AI/RAG systems, internal tools, dashboards, CRM/ERP/POS systems, logistics platforms, marketplaces, real estate software, e-commerce, FinTech, EdTech, HealthTech, data analytics, travel, hospitality, and regulated sports betting The value of that experience is not just knowing different industries. It is knowing the patterns behind them: workflows, permissions, payments, reporting, integrations, data integrity, performance, edge cases, and the business logic that quietly decides whether a product becomes scalable or painful. I personally lead architecture, planning, communication, and delivery. When a project needs more capacity, I bring in my senior team to provide high-level technical ownership and reliable execution. Whether you are a non-technical founder, an operations-heavy business, or a technical team that needs senior delivery support, I will communicate at the right level: clear when needed, technical when useful, and always focused on decisions that move the project forward. I am based in Turkey and regularly work with US, UK, Canadian, European, and Australian clients. I work EST hours with reasonable PST overlap, so communication across time zones is smooth. Don’t settle for mediocre. In a world of ruthless competition, make me your unfair advantage. Send me a message today, and I will map our next steps.
