⭐ Top Rated Plus | 100% Job Success | $100K+ Earned 💻 React / Next.js / TypeScript - Modern Full-Stack + AI ✅ 85 Jobs Completed · 2,300+ Hours on UpWork Key Skills: React.js / Next.js / TypeScript / Node.js / JavaScript / API Design / Tailwind CSS / Headless CMS / AI Integration / HTML / CSS I'm a British full-stack web developer with 20 years of professional experience, having started in the industry back in 2005. For the past five-plus years on UpWork I've maintained a 100% Job Success score across 85 completed projects - a record I'm proud of, because it reflects how I work: carefully, communicatively, and with a focus on getting things right the first time. What I build: I specialise in modern web applications built with React, Next.js, and TypeScript. These days that means production-grade apps with proper type safety, sensible architecture, and clean, maintainable code - not just front-ends, but the API layers and integrations behind them too. Whether you need a marketing site that loads instantly, a complex internal tool, or a customer-facing SaaS product, I can take it from brief to deployment. A growing part of my work involves AI and bespoke solutions: integrating language models into existing products, building custom tooling, and helping clients work out where AI genuinely adds value versus where it's just noise. If you have an idea that doesn't fit an off-the-shelf template, that's exactly the kind of project I enjoy most. How I work: TypeScript depth and code quality matter to me. I write code that the next developer - possibly you, possibly someone you hire later - can actually read and extend. I don't cut corners that turn into expensive problems six months down the line. I also take communication seriously. As a native English speaker, I can absorb a brief quickly and ask the right questions early, which saves time and avoids the back-and-forth that derails projects. You'll get clear updates, honest timelines, and a heads-up the moment something needs a decision from you - no surprises. Reliability is the other half of it. When I commit to a deadline, I plan the work to hit it. Clients come back to me because delivery is predictable, and because I treat their project as if the outcome were my own. Best fit for: I'm a strong fit for high-value project builds where quality and dependability matter more than the lowest bid - SaaS products, web applications, AI-integrated tools, and substantial site builds. If you're looking for someone to own a project end to end and deliver it properly, we'll work well together. Thank you for taking the time to read my profile. I'd be glad to discuss your project - feel free to send the details over and I'll come back with honest thoughts on scope, approach, and timeline.

Founder of thegemstech | SaaS Architect | Full Stack Product Engineer | AI & Scalable System Specialist I help startups, founders, and businesses build scalable digital products designed for real-world growth — not just demo-level applications. Most developers can build features. Very few understand how to build systems that survive real business operations, scaling challenges, performance pressure, and future expansion. That’s where I specialize. I’m a Full Stack Developer with strong experience in: • React.js / Next.js • Node.js / Express.js • MERN Stack • PostgreSQL / MongoDB • SaaS Architecture • AI Integrations • REST APIs • Real-time Systems • Scalable Backend Infrastructure I’ve worked on production-level platforms including: • RestroCash — Restaurant & Hospitality SaaS Platform • GreenMove — Transport & Booking System • AI-powered CMS Platforms • Marketplace & Multi-tenant Systems • Real-time Dashboard Applications My approach is business-first and architecture-first. Before development starts, I focus on: • Scalability • System architecture • Database structure • Performance optimization • Long-term maintainability This helps clients avoid expensive rebuilds and technical debt later. I value clean code, strong communication, reliable execution, and long-term collaboration. If you're building a serious product and need someone who understands both technology and business systems, let’s connect. — Lokendra B. Jargha Founder, thegemstech

You want to work with someone who has already built and scaled real products — not someone figuring it out on your project. Most web apps don’t fail because of bad ideas — they fail because they’re slow, hard to scale, or poorly built… and by the time you realize it, you’ve already lost users, rankings, and revenue. I fix that. I help founders and teams build fast, scalable web apps using React and Next.js — or improve existing ones that are underperforming. Recently, I improved a frontend to achieve a Lighthouse score of 90+, reducing load time by 40–60%, improving Core Web Vitals, and leading to a 20–30% increase in conversions — with sales growing from $100k+ to $300k+.saving thousands in Google Ads that were previously underperforming due to poor frontend performance. With 5+ years of experience in frontend and fullstack development, I focus on building products that don’t just work — but actually perform under real-world usage. If your app feels slow, messy, or hard to scale — I can quickly identify what’s wrong and fix it. 💡 How I can help • Build fast, SEO-friendly frontends using React & Next.js • Develop fullstack applications (Next.js, Django, APIs, databases) • Turn MVPs into scalable, production-ready systems • Fix slow, buggy, or hard-to-maintain applications • Improve performance (Core Web Vitals, Lighthouse optimization) • API integration & backend connectivity 🤖 AI Integration & Modern Features • AI-powered web apps (OpenAI / LLM integrations) • ChatGPT-style interfaces in React / Next.js • AI dashboards & data-driven UI • Adding AI features to existing SaaS products • Automation workflows using AI APIs I can help you add AI features to your product without overcomplicating your stack. 📈 Recent work & impact • Improved frontend performance → Lighthouse 90+ (faster load, better SEO) • Built fullstack app from MVP → scalable production system • Optimized performance bottlenecks and improved user experience • Developed clean, maintainable architecture for long-term scalability ⭐ What clients say • “Quick to understand the problem and suggest practical solutions” • “Delivers clean, scalable code — not just quick fixes” • “Strong focus on performance and real-world impact” • “Easy to communicate and reliable throughout the project” If you’re building a product — or struggling with performance — let’s start with a small task. If you’re not satisfied, I’ll refund it.
