    Do you have a great idea for a web or mobile app but not sure where to start? I specialize in designing and developing web and mobile apps from scratch. -Top 1% in app development by Upwork -My clients apps have raised $330M+ USD and made it to Frobes -Trusted by Harvard, Yamaha, UC Berkeley & Samsung -100+ 5-star reviews across different platforms (UpWork, Clutch, Yelp) About a decade ago I launched my startup called SchooLinks with no tech background. I hired the wrong freelancers, used the wrong tech stack, and made many other expensive mistakes along the way. It was a nightmare to say the least. I learnt that "cheap" can be expensive. While anyone can design or code, very few can create products that not only scale but also remain stable over time. This is especially critical when developing MVPs (Minimum Viable Products) and POCs (Proof of Concepts), where the right approach can make the difference between success and costly failure. After 2 years, I was able to finally launch SchooLinks. It has raised over $10 MM USD and became the industry leader of its category. I learnt to design, code and went back to school at UC Berkeley, where I became the VP of Technology for Entrepreneurial Association. During my time there, I helped dozens of startups launch their apps! This experience led me to want to help other fellow entrepreneurs and business owners to avoid the expensive mistakes I made. As a result, my clients have raised over $250 MM USD with web and mobile apps I helped them launch. You can count on me being upfront when I don’t think we are a good fit and point you in the right direction. I believe this has led me to be on the top 1% on UpWork and have over 100+ 5-star reviews across different platforms (UpWork, Clutch, Yelp). Schedule your consultation today! My preferred tech stack includes: Figma, Flutter, NodeJS, Angular, AWS & MongoDB. I also have solid experience integrating API’s, including Stripe, ChatGTP and Twilio.

    👋 Hey, I'm Drew from San Francisco! Over the last few years I've worked with small to medium-sized businesses all the way up to giants like Microsoft. I've also taught at App Academy, the most prestigious web development bootcamp in the United States. As a software engineer, I've helped build everything from complex UIs and animations, web scrapers, to full stack web, mobile, and desktop applications. And if you've attended an online college, easily trained a custom machine learning model without writing a line of code, or trained a machine learning model in AI Builder to integrate into a Power App; you've likely used code I've worked on! 🖼️ See my portfolio: portfolio.drewrodrigues.com 💻 And my code here: github.com/drewrodrigues

    I'm an experienced software engineering leader with over 15 years of experience driving innovation in design, architecture, and implementation. I specialize in building scalable private social networks capable of handling millions of daily requests with minimal intervention and near-zero downtime.   At California Labs, I co-founded Loop, a B2C company that revolutionized family connections through a private social network app and Wi-Fi-connected digital picture frame. I led the engineering team's growth, scaling it from 3 to support over $7 million in sales, achieving featured placement in Best Buy and Amazon. We achieved an industry-leading NPS score of 53, demonstrating exceptional customer satisfaction.   As a full-stack architect and leader, I managed hardware, firmware, mobile, backend, QA, and web teams. We designed and shipped two generations of hardware within tight deadlines, with one iteration completed in just one year. I hired the entire engineering staff, ensured infrastructure scaled with company growth, and utilized remote developers to deliver high-quality software on budget.   Prior to California Labs, I served as a Senior Engineering Manager at Zynga, where I led high-performing engineering teams across diverse platforms (Android, iOS, Windows Mobile, Web) for the Words with Friends franchise. I implemented agile development pods, maximizing engagement and retention, and collaborated with product and design to implement revenue-boosting features. I also oversaw the game's largest expansion with multilingual gameplay and professional dictionaries, and optimized the Android client.   I am passionate about developing talent and performance, and have managed performance reviews, promotions, and bonus recommendations for team members throughout my career. I am a results-oriented leader with a proven track record of success in building and scaling high-performing engineering teams.   My work on the Loop digital photo frame project garnered recognition from Time Magazine, New York Magazine, and Wired. I am also the recipient of the prestigious 'Atlas Hero Award' at Zynga.
