I'm an accomplished engineering manager and full-stack developer with over a decade of experience leading high-performing teams and building scalable SaaS platforms. Specializing in React, Node.js, .NET, and AWS, I excel at architecting cloud-native solutions, modernizing CI/CD pipelines, and delivering user-focused applications. My career spans impactful roles at Autodesk, Clearsurance, and Idemia, where I’ve driven technical excellence and business outcomes, including systems handling $200M+ in contracts and reducing CI/CD overhead by 40%. What I Do Best: Full-Stack Development: Designing and building end-to-end applications with React, AngularJS, and Node.js for seamless, high-performance user experiences. Cloud & DevOps: Architecting scalable, fault-tolerant AWS infrastructure and optimizing CI/CD pipelines with Jenkins and Docker for reliability and efficiency. Technical Leadership: Leading agile teams, mentoring engineers, and aligning roadmaps with business goals to boost velocity (e.g., 25% increase at Idemia). System Modernization: Transforming legacy systems (e.g., Ruby on Rails to modern stacks) to enhance extensibility and performance. API & Integrations: Developing robust integrations with platforms like Microsoft Dynamics CRM and InRule for streamlined workflows. With a B.S. in Computer Science & Mathematics and certifications as a Scrum Master and Microsoft Dynamics CRM specialist, I bring a strategic, results-driven approach to every project. I’ve delivered high-availability systems (99.99999% uptime), improved Lighthouse SEO scores by 20%, and built hobbyist games in Unity and Monogame. Whether you need a scalable app, cloud migration, or team leadership, I’m here to deliver measurable impact. Let’s collaborate to turn your vision into reality!

I build custom web applications, dashboards, and automation systems using AI as a development partner with me driving the product vision, architecture, and quality control from start to finish. My background is product management first, development second. I spent eight years as a product manager, UX designer, and web developer at a media company with over 20 million monthly visitors, and I've since crossed fully into hands-on development, building production-grade tools solo using AI-assisted workflows. I work across two stacks depending on what the project needs: WordPress and WooCommerce -- custom plugins, theme development, WooCommerce extensions, third-party API integrations, server configuration, and performance optimization. React -- component-based web apps and dashboards, with clean UI and state management. Across both, I bring experience with PHP, JavaScript, REST APIs, Stripe, CRM platforms (HubSpot, Salesforce, Pipedrive), and marketing automation tools (Mailchimp, SendGrid). What makes me useful on a project: - I think like a product manager, so I can take a vague brief and turn it into a scoped, buildable plan - I create clean, documented code and can explain every decision I make - I've worked in fast-paced startup environments where ownership and communication matter as much as technical output I'm best suited for clients who need someone who can own a project end-to-end, not just execute a feature list someone else defined.

Most $1–5M businesses hit the same wall: you've outgrown off-the-shelf tools, but a custom software agency wants $50K and six months. I close that gap. I design and build custom software for small businesses: client portals, internal tools, dashboards, automated workflows, and AI-powered systems, using an AI-native development workflow (Claude Code) that lets one senior builder deliver what used to take a team, in weeks instead of quarters. And because I spent 20+ years on the revenue side of businesses (digital marketing, email, CRM) before building software, everything I ship is wired to a business outcome: more revenue, less manual work, cleaner data. WHAT I BUILD • Custom web apps and client portals (Next.js, Supabase, Vercel) • AI integrations and agents that automate real workflows • CRM and marketing automation systems (GoHighLevel, ActiveCampaign, HubSpot) • Email infrastructure that actually reaches the inbox (Resend, Beehiiv, plus deep deliverability expertise) • Business process automation that connects the tools you already use HOW I WORK Strategy first. Before I write a line of code, I map your revenue model and operations so we build the highest-ROI system first. Then I build fast, document everything, and hand you something your team can actually run. WHY CLIENTS HIRE ME • Top Rated Plus (top 3% on Upwork), 100% Job Success, $100K+ earned • Recently architected and shipped a complete custom software platform for a client: app, database, hosting, transactional email, newsletter, and automation stack, end to end • Rare hybrid: full-stack developer + growth strategist. I don't just build the system; I make sure it grows the business. Ideal fit: service businesses, agencies, and local businesses doing $1M–$5M in revenue that need custom software and automation without enterprise pricing. If your growth is bottlenecked by manual processes, disconnected tools, or software you've outgrown, send me a message or book a consultation. Tell me the bottleneck, I'll tell you exactly what I'd build. 🏆 Reviews and feedback from clients 🏆 The client reviews below describe the quality of work and value that you can expect from working with me. ⭐⭐⭐⭐⭐ "Tom Polifka you're a genius at online business, but also at helping "regular" brick and mortar entrepreneurs to see how online business tools can enhance their practice!" - JoAnn Keller, Hands For Living ⭐⭐⭐⭐⭐ "I never thought I'd be an online yoga business owner until Tom convinced me to put my yoga training online. My yoga studio closed in 2020 and now it's a global community. You can tell Tom cares about you and wants you to succeed." - Angela Wagner, Angela Wagner Yoga ⭐⭐⭐⭐⭐ "When I started working with Tom I didn't have any systems in place and was functioning in a hot mess. I had 100K followers on IG but not the sales to show for it. I just had my first six-figure year and 100% it would not have happened without his guidance." - Kelsey Rowell, Whole Life Nurse
