Iโm 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 growsโnot 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. Iโm often brought in to take ownership of the application layer and make sure it holds up after launch.
What I take responsibility for:
โข Frontend development using React, JavaScript (ES6+), and TypeScript
โข Backend APIs with Node.js and Express
โข Authentication, role-based access, and business logic
โข Payments, subscriptions, and admin workflows
โข AWS deployments, environments, and production readiness
โข Fixing performance bottlenecks and stabilizing fragile codebases
Iโve worked on 250+ projects across SaaS, fintech, healthcare, and education, including products used by thousandsโand in some cases millionsโof users.
Selected work:
โข Fleek โ Subscription management SaaS with 1M+ users
โข ClashUp โ Short-form video platform with AI-based moderation
โข MCCQBank โ Medical exam prep platform with live classes
โข 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 launchโnot before.
Iโm available up to 40 hrs/week and happy to start with a quick 10-minute call to see if weโre a good fit.
