I'm a full-stack JavaScript/TypeScript developer with over 5 years of experience building scalable and maintainable web applications wiwht backend. My expertise spans React.js, Next.js, Node.js, and NestJS, with strong foundations in both SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) databases. I specialize in helping startups move fast without sacrificing long-term code quality -delivering lean MVPs that are designed to scale. From architecture decisions to deployment strategies, I focus on building systems that can evolve as business needs grow. I've built and deployed multiple React Native apps powered by Firebase, leveraging its authentication, Firestore, cloud functions, and push notifications to enable real-time, scalable mobile experiences. ✅ Core Skills & Experience ## Web Development • Advanced React.js and Next.js: SEO-optimized, high-performance SPAs and SSR applications using Hooks, Redux Toolkit, Context, and TypeScript. • Clean UI architecture with Tailwind CSS, Styled Components, and precise Figma-to-code execution. • Scalable design patterns, lazy loading, and performance-first development. ## Backend Engineering • Node.js & NestJS for modular, testable API architecture — featuring RBAC auth, validation, file uploads, and background processing (BullMQ). • REST and GraphQL API design with real-time features (WebSockets/Socket.io). • Error tracking, logging, and graceful failure handling at scale. ## Databases • SQL (PostgreSQL, MySQL): schema modeling, relational design, migrations, performance tuning. • NoSQL (MongoDB, Firebase, Supabase): flexible data models, real-time sync, access rules, cloud functions. ## Scalability & MVP Strategy • MVP-first thinking: fast iteration cycles, reusable components, lightweight backend layers. • Scalability focus: environment-based configs, service separation, caching strategies, and database indexing from day one. • Designed and scaled apps serving thousands of users with minimal overhead. ## DevOps & QA • CI/CD (GitHub Actions, GitLab), Docker-based deployments, Vercel, AWS, Railway. • Robust testing: unit (Jest), E2E (Cypress, Detox), and API tests (Postman). • Git-based workflows, Agile practices, strong async collaboration. ## Mobile Development • React Native expert: custom animations, navigation flows, background services, and native module integration. • Cross-platform delivery with full CI/CD support and OTA updates (CodePush, EAS). • Bonus: Flutter, Swift, and Kotlin experience for native enhancements. I thrive in product-driven environments where velocity meets technical excellence. Whether you're validating a new idea or preparing for scale, I bring full-stack expertise, clear architecture thinking, and a collaborative mindset to help you deliver real impact-fast. Let’s build something future-ready, whether it's your next MVP or a scale-up milestone.

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

Let me help you develop an awesome app using Next.js. You'll be amazed at how quickly, together, we can go from idea to polished app. Excelling in Software Engineering today starts with one's ability to evaluate and choose which open-source products and resources to integrate into your solution without drowning in the ever-changing ocean of choices. Making the right choice from the many options available will determine how well a solution stands the test of time. When asked to create a mobile web app to replace an iPhone and Android app I chose to create a Progressive Web App using React and React-Bootstrap with a GraphQL data access layer. On the server, I created a java based GraphQL service replacing web services. Web application, including GraphQL service and access to PWA, is deployed on Tomcat. When I was asked to develop an enterprise authentication solution for our product suite, I chose to base our IAM product on WSO2 Identity Server and implement OpenID Connect in our products using the Nimbus OAuth 2.0 SDK. For a reporting solution, I chose to base our product on JasperReports Server. And, for a solution to consume and transform HL7 messages, I chose Mirth Connect. I enjoy solving complex technical problems through research, analysis, and design, working independently and as part of a team. I strive to create solutions that are scalable, maintainable, and performant.

I’m a developer with experience building websites and web applications (progressive web apps). I like to write clean concise code using vanilla javascript.
