Iโ€™m a Top Rated Senior Full Stack Developer with 12+ years of hands-on experience building and scaling React + Node.js SaaS applications used in real production environments. I typically work with founders and product teams who need someone reliable to build fast, think through edge cases, and keep systems stable as usage growsโ€”not just ship features and disappear. Most of my work revolves around React + Node.js platforms, including customer-facing web apps, internal dashboards, subscription systems, and admin tools. Iโ€™m often brought in to take ownership of the application layer and make sure it holds up after launch. What I take responsibility for: โ€ข Frontend development using React, JavaScript (ES6+), and TypeScript โ€ข Backend APIs with Node.js and Express โ€ข Authentication, role-based access, and business logic โ€ข Payments, subscriptions, and admin workflows โ€ข AWS deployments, environments, and production readiness โ€ข Fixing performance bottlenecks and stabilizing fragile codebases Iโ€™ve worked on 250+ projects across SaaS, fintech, healthcare, and education, including products used by thousandsโ€”and in some cases millionsโ€”of users. Selected work: โ€ข Fleek โ€” Subscription management SaaS with 1M+ users โ€ข ClashUp โ€” Short-form video platform with AI-based moderation โ€ข MCCQBank โ€” Medical exam prep platform with live classes โ€ข Perifit โ€” BLE-enabled FemTech mobile app used globally Core stack: React, Node.js, JavaScript, PostgreSQL, MongoDB, AWS I focus on clean, maintainable systems, because most real problems show up after launchโ€”not before. Iโ€™m available up to 40 hrs/week and happy to start with a quick 10-minute call to see if weโ€™re a good fit.
