I build and scale real production systems using Ruby on Rails, Node.js, Laravel, React, Next.js, MERN, PostgreSQL, MySQL, MongoDB, and AWS. Over fifteen years and more than thirty Upwork projects, I’ve delivered SaaS platforms, API architectures, e commerce systems, marketplace engines, cloud migrations, DevOps pipelines, and full stack applications that power real businesses, not prototypes. Rails apps struggling with performance. Node.js APIs breaking under traffic. Laravel backends falling apart during payment flows. React and Next.js front ends slowing down user activation. AWS setups missing DevOps structure. These are the systems I fix, redesign, and scale. I work as a system architect, not a “feature developer”. My experience spans Ruby on Rails, MERN stack, Node.js, Laravel, React, Next.js, AWS architecture, Docker, Kubernetes, CI/CD, and everything required to turn a fragile product into a stable, scalable platform. 🧠 𝐂𝐎𝐑𝐄 𝐄𝐍𝐆𝐈𝐍𝐄𝐄𝐑𝐈𝐍𝐆 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄 (𝐊𝐞𝐲𝐰𝐨𝐫𝐝 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐞𝐝) 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 React, Next.js, Vue, Node.js, Ruby on Rails, Laravel, MERN stack SPA architecture, component systems, REST APIs, GraphQL, micro front ends, modular monoliths, multi tenant SaaS.

My Process 💪 Step 1 — Free brief + audit. Send your idea, prototype, Figma files, or existing codebase. As a React Native Developer and Full Stack Developer, I review architecture, scope, risk, and feasibility across mobile and web — no charge, no obligation. Most audits turn around within 24–48 hours. Step 2 — AI-powered prototype. Using Claude Code, Cursor, and OpenAI/Gemini integrations, I build a working, testable React Native or React Next.js prototype in 3–7 days, not months — so you validate real demand before committing to full development. This is the same AI-driven approach that's cut manual workflows by 30–50% and shaved 30–40% off time-to-market on past projects. Step 3 — Build. Full-stack build across React Native Mobile, React Native Expo, React Native Firebase, and web (React, Next.js, Node.js, Supabase/PostgreSQL, MongoDB), with weekly demos so you always know exactly what's shipped and what's next. Sprints run in 1–2 week cycles with clear, measurable milestones — the structure behind 100+ delivered projects and 60+ full production launches. Step 4 — Launch + scale. Deployment (AWS, Google Cloud, or Azure), CI/CD, monitoring, and post-launch optimization — the same DevOps React Native process that's taken apps from 0 to 100K+ MAU, 99.9% uptime, and 5M+ requests/month, while cutting infra overhead by 35% and backend costs by 40%.

When a product requires a unified stack, I seamlessly connect frontend and backend using react node, and I’m fully comfortable stepping into full stack developer mern projects. This approach reflects true react full stack delivery - I take full ownership as a react full stack developer, ensuring features are scalable, maintainable, and production-ready. When needed, I step in as CTO and software project manager (and sometimes an ERP consultant for internal ops): architecture, roadmap and execution- plus business consulting focused on outcomes, timelines, and budgets. I’m comfortable in production: database design, migrations, performance, and dba-style care; nginx basics; payments with stripe; integrations with shopify; AI features via openai. I’ve shipped niche verticals too - med spa platforms, web3 apps, trading software dashboards, and even website development perfume projects. I’ve also implemented playful mechanics like a coin flip while keeping compliance in mind (including gambling-related UX constraints). ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬 𝐈 𝐡𝐚𝐯𝐞 𝐰𝐨𝐫𝐤𝐞𝐝 𝐰𝐢𝐭𝐡 as Full stack Developer React Node ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ▸ Logistics & Supply Chain ▸ Fintech & Crypto ▸ Health & Wellness ▸ Food & Restaurant Management ▸ Real Estate ▸ Social Media ▸ Education & E-Learning I ship modern website work as a web developer / full stack web developer / full stack website developer, support CMS builds as a wordpress developer (front end wordpress) or with drupal. I also deliver outside JS when it fits: laravel and full stack developer laravel (including laravel vue), ruby on rails, python work and python full stack developer engagements; plus enterprise builds in full stack .net and senior full stack .net. I collaborate closely with ui ux / ui/ux teams - sometimes acting as a ui ux web designer partner, pairing with a ux designer.
