With over four years of in-depth experience in Full-Stack development, I have honed my skills in designing and building both Web & Mobile Applications that are not only efficient but also scalable and maintainable. My technical expertise is rooted in JavaScript and extends across the MERN (MongoDB, Express.JS, React.JS, Node.JS), MEAN (MongoDB, Express.JS, Angular.JS, Node.JS), and MEVN (MongoDB, Express.JS, Vue.JS, Node.JS) stacks, where I leverage MongoDB for robust data management, Express.js for creating powerful APIs, and Node.js for server-side logic. On the Frontend, I have extensive experience with React.JS, Angular.JS, and Vue.JS, enabling me to develop intuitive and responsive user interfaces that enhance user experience. My work with React Native has further solidified my ability to deliver cross-platform mobile applications with native performance. Beyond just development, I am well-versed in cloud services, particularly AWS, where I utilize tools like Lambda, S3, and DynamoDB to create scalable, secure, and cost-effective solutions. My experience also encompasses API integration, where I seamlessly connect various services and data sources to create unified, efficient systems. I pride myself on my ability to understand complex business requirements and translate them into technical solutions that drive results. Whether it’s architecting a new system from the ground up or optimizing an existing application, I am dedicated to delivering high-quality work that exceeds expectations. Furthermore, I have a proven track record of designing and developing robust, scalable applications that meet the evolving needs of businesses and users alike.

I’ve brought complex SaaS products to life for my clients — and I’m ready to do the same for you. With a holistic approach to development, each step is intentional and thoughtful, keeping your business goals front-and-center. Rather than simply carrying out tasks, I consider technical problems from many angles. This helps the project not only meet immediate goals, such as creating a working feature, but also managing data usage and scalability into the future, translating into stability and cost savings. As one client told me, “You’re not all 1’s and 0’s.” He explained how my forethought and attention to detail for his business were rare qualities, when finding a developer. This critical thinking and mindfulness mean that I can help guide you and strategize with you – over the short-term and the long-term. Every project starts with gaining a thorough understanding of your goals, both in terms of business and technology. What is your business roadmap? How many users do you anticipate, and when? Which features take priority, and how feasible are they to implement with the tools currently available? What potential roadblocks can we already see — and how can we remove them as soon as possible? Questions like these are how we can bring your new software idea into reality. Another way that I go beyond 0’s and 1’s is with design. I focus on modern, strategic, and clean layouts and aesthetics, bringing Tailwind UI into play for any website or app. To see my development and design in action, please take a few minutes to watch the Bee Portfolio and Wedding Day Timeline walkthrough videos in my Upwork Portfolio. (As you’ll see between those two examples in particular, I’m very comfortable working across different industries, quickly learning the key concepts and relevant details, such that I can provide the best technical solutions to the problems your industry faces.) My Core Focuses: • Front-End App Development • Back-End App Development • Business Website Design & Development Front End: • Vue 3 / Typescript / Nuxt 3 / Tailwind CSS • Netlify hosting • Progressive web app (PWA) • Front-end cache (indexedDB) • Sentry • Google Tag Manager Back End: • Typescript / Node.js / Express • MongoDB (+ complex aggregation) • Microservices architecture • Google Cloud + Cloud Build CD + Cloud Run / Cloud Run Jobs + Memorystore (Redis) + PubSub + VPC network for Cloud Run static IP + IAM / Service accounts • Sendgrid email • Slack integration Security: • Advanced JWT flow • Refresh token rotation & automatic reuse detection • XSS attacks • Sanitization • CSP Directives • Third-party asset integrity • CSRF prevention • Clickjacking prevention • Man-in-the-middle attack prevention

-Tools/Platforms/Software- -Standard Google Workspace Apps: Sheets, Forms, Docs, Gmail, etc. -Automation: Google Apps Script, Zapier -Form Builders: Cognito, Google Forms, Jotform, Typeform, Gravity Forms -Diagram and Visualization: Miro, Zoom Whiteboards, Sheets, Looker -Project Management: Trello, Google Sheets/Calendar, Monday.com -Communication: Gmail -How The Tools I Build With Can Be Applied- -Business Process Automation (e.g. automate your recurring processes) -Alerts and Reports (Generate and send reports to customers, stakeholders, etc.) -Data Visualization and Analysis -Integration with Your Platforms(Do all of the above by connecting the apps you use to your Google environment) -What I Can Do For You- I design process automation systems, integrations, and BI dashboards centered around Google’s environment. Google makes it easy to share/set permissions for every person that needs access to your systems and has a thriving ecosystem of freemium plugins that facilitate integrations with other services like Trello, Quickbooks Online, Salesforce, Shopify, etc. If free-tier plugins are insufficient or missing desired features, the Apps Script environment makes the development of custom functionality seamless. If you would like to discuss what more can be done to make your life easier with the platforms you are already paying for, just shoot me a message so we can set up a call. -About Me- I started designing BI Dashboards back in 2016 at BellTower Technologies LLC. During my time at BellTower Technologies, I created many BI dashboards in Google Sheets used by nearly every employee. The projects I worked on ranged from dashboards for tracking workflows to KPI visualizations used daily by the CEO, several of which are still used today. I also attended Texas A&M to study computer science on an engineering scholarship starting in 2019 but left during the pandemic to work. A couple of systems I have designed and implemented recently are: -Automated document generation using Google Doc templates and data in Sheets(Either manually input or automatically collected) -A small Trello/Google Forms integration -An integration between Enlighten, a well known solar system management platform, and Google Sheets -Mail-merge configured through an interface in Google Sheets
