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 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. No questions asked. 🔍 Technologies & Expertise Frontend: React.js, Next.js, TypeScript, JavaScript (ES6+), Tailwind CSS Backend: Node.js, Django, REST APIs, GraphQL Database: PostgreSQL, MongoDB Focus Areas: Performance Optimization, Core Web Vitals, Lighthouse, SEO Optimization, SaaS Development, MVP Development, Dashboard Development, AI Integration, LLM APIs, ChatGPT Interfaces, API Integration, Web App Scaling, Clean Architecture

High-fidelity 3D on the web is either a powerful revenue driver or a massive performance liability. As a vetted Top Rated specialist, I ensure your technical investment stays ROI-positive. I am a Software Engineering graduate (ASTU) and an A2SV Member (Silicon Valley-vetted), specializing in the high-stakes engineering required to bring desktop-grade 3D performance to the mobile browser. While most developers focus on making things "look cool," I architect the underlying SPATIAL LOGIC ENGINES that make complex data interactive, scalable, and lightweight. HOW I DE-RISK YOUR TECHNICAL INVESTMENT: • EXTREME ASSET OPTIMIZATION: Proven track record of reducing unoptimized 50MB+ industrial payloads to <3MB (a 94% reduction). I ensure your users experience 60FPS fluidity on mobile devices without crashing the GPU. • INDUSTRIAL LOGIC & PRECISION: I architect browser-based environments with millimeter precision. From custom transformation gizmos to 1:1 coordinate mapping for CNC manufacturing, I handle the complex linear algebra most developers avoid. • MODULAR "HEADLESS" ARCHITECTURE: I deliver 3D components that are fully configurable via JSON. This allows your team to tune camera optics and shader luminance in real-time without touching the underlying GLSL code. • VISUAL INTELLIGENCE: Utilizing custom shaders and FBO (Frame Buffer Object) physics, I transform flat data into volumetric, luminescent point clouds and stylized high-fidelity environments. MY TECHNICAL MOAT: • Core Graphics: Three.js, React Three Fiber (R3F), GLSL/WGSL Shaders, Blender. • 3D Mathematics: Linear Algebra, Vector Calculus, Manifold Logic, Algorithmic Geometry. • State & Logic: Zustand, TypeScript, Next.js, Physics (Rapier/Cannon.js). • Motion: GSAP (ScrollTrigger/Flip), High-performance GPU interactions. THE ENGINEERING STANDARD: I bridge the gap between Silicon Valley-standard algorithmic rigor and world-class interactive aesthetics. I don't just "write code"—I engineer technical assets that your competitors cannot copy. I prioritize high-impact technical partnerships with firms that value engineering precision. If you are ready to transform complex data into a high-performance 3D asset that drives results, let’s discuss your project requirements.
