For over a decade, world-series winning professional baseball teams, top universities, premier hospitals, VC-funded startups, digital agencies, marketing firms, and small business owners have placed their trust in me for their critical tech projects - and you can too, if you want. I’m Pat, a senior-level software engineer from the USA. And if you're looking for... Someone you can trust to deliver quality work, and — above all — tangible results, then you are in the right place. Because there's a good chance you need more than a freelancer to do a task; you need a collaborator who’s successfully weathered the storm, time and time again. That's why when we work together, you're NOT getting: ❌ Someone diving into the "deep end" for the first time ❌ Unanticipated budget "surprises" ❌ Final products that miss the mark ❌ Security vulnerabilities ❌ Someone whose stretched too thin across projects ❌ A lack of transparency and communication ❌ Nonexistent post-project support Instead, you get a professional who: 💰 Respects the weight of your decisions 💰 Values the trust you place in them 💰 And is committed to delivering results. Whether you're looking to: ✅ Build ✅ Refine ✅ Innovate ✅ Troubleshoot ✅ Or simply seek advice... Consider it done. I bring over a decade of expertise to the table, and even 'Top Rated' and 'Rising Talent' accolades from Upwork (when I first started on here). If you only need someone to write some code here and there, I'd look elsewhere. Rather, I'm here to help you sidestep stress, make informed decisions, and breathe life into your ideas. So, now that you know a bit about me... Here’s how I’ve brought my clients' visions into reality, and how I may be able to do the same for you... 🚀 Architected 20k-message/day chat system, boosting engagement (Previous Employer) 🚀 Devised email platform, enhancing deliverability and message-to-market match (Own Company) 🚀 Achieved 87% cost cut migrating AWS to Heroku (Upwork/Agency Client) 🚀 Engineered Stripe system, optimizing ed-tech transactions (Upwork/SaaS Client) 🚀 Built custom headless CMS for rapid content creation and testing (Own Company) 🚀 Performed security audits, eliminating fraudulent Stripe charges (Upwork/Agency Client) 🚀 Implemented workflow system, reducing complexity (Own Company) 🚀 Optimized Shopify store, boosting speed by 20% and SEO (Upwork/E-commerce Client) 🚀 Migrated NextJS codebase to Google Cloud (Upwork/SaaS Client) 🚀 OAuth integrations for Facebook, Google, Twitter (Upwork/SaaS Client) 🚀 Meta Pixel and GTM audit (Upwork/Youtube Influencer) 🚀 Audited complex AWS setup, resulting in reducing monthly bill from $120 to $0.05 (Upwork/Agency Client) 🚀 Self-taught PHP/MySQL, building innovative medical stock alert system over SMS (Peace Corps Volunteer) 🚀 Built data dashboards to optimize ticket sales (MLB) 🚀 Created HIPAA-compliant cloud systems for a leading hospital's research (Hospital) 🚀 Developed an online platform for a premier university, enhancing e-learning (University) 🚀 And much more... In fact... Over the years, I've sharpened my skills to deliver not just robust technical solutions but also innovative strategies that strengthen your business. I can help you with things like: 👉 Creating Dynamic, Data-Driven User Interfaces 👉 Developing Robust and Scalable APIs for Mobile and Web Applications 👉 Optimizing Frontend Performance, Enhancing User Experience 👉 Ensuring Website Accessibility and Compliance 👉 Architecting and Implementing Scalable Backend Systems 👉 Debugging and Refactoring Legacy Code for Performance 👉 Strategizing and Executing Cloud Migrations or Optimizations 👉 Developing and Integrating Secure Payment Systems 👉 Optimizing E-comm Stores for Better Conversions 👉 Performing In-depth Security Audits and Fortification 👉 Creating Custom, Efficient Content Management Systems 👉 Crafting and Optimizing Data Models for Scalable Applications 👉 Designing and Implementing API Integrations 👉 Providing Strategic IT Consultation and Roadmap Planning 👉 And much more! So, with that said, here's my promise to you: From concept to code, your vision is safe with me. Remember, you don’t just get a coder. You get a collaborator who works to understand your business, navigate its challenges, and craft solutions that just make sense for you. Expect transparent communication, strategic problem-solving, quality, flexibility, proactive initiative, and security, all wrapped in one. So... If you are ready to make smarter decisions, ditch the stress, and actually see your ideas come to fruition... Send me a message now. Pat

tl;dr Tech I know: Python and Flask with Peewee, Ruby for scripting or for Rails 2.3.8 - 5, React with Flux architecture, AWS, Postgresql, Node.js, PHP, plus a billion other things around deployment, server provisioning, infrastructure, etc.. I'm an Ivy League trained Software Engineer that has often straddled the line between business and tech, mostly in startups. I'm well versed in agile and remote team management. Most recently, VP of Eng for a Financial Tech startup. My passion has been programming for as long as I can remember and I'm really good at it; I can make things quickly or I can make things correctly and I try to make sure you know which one you're getting when we work together. My strengths include: * Back-end server programming and provisioning. I'll setup / configure your servers for you, design the architecture of your application, and build it using the latest framework (Laravel or Rails 5). Can optimize for speed or for quality well-documented, maintainable code - you pick * Data scraping and analysis. I've written web scrapers in Ruby and Node.JS. I've architected and built a custom analytics system also * Getting everybody's expectations on the same page My coolest projects: * Ayalo, A product aggregator for traditional retail stores in Guatemala and Mexico. I built the first version of the product (3 systems in different languages / frameworks), then built a team of 5, and managed them + built alongside them. * A custom analytics system (internal to Ayalo) that includes data warehouse design, ETLs, URL-based page tracking, and custom event tracking. Basically, record everything then see what we can learn :) * Callback counter for Node - github:frankpinto/canicas
