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
