♠️ Many businesses lose revenue daily due to slow load times, weak product pages, poor frontend architecture, and disconnected integrations. I solve these problems by building clean, performance-first Shopify stores and React-powered web applications that turn visitors into paying customers. I'm a Frontend & Shopify Developer with 7+ years of experience building, optimizing, and scaling high-converting digital experiences for brands that demand excellence. What makes my background rare is this: most Shopify developers know the platform. I know the web. I've spent years going beyond theme customization, studying frontend architecture, typography, color theory, spacing systems, and performance engineering, so when I work on your Shopify store, you're not paying for surface-level edits. You're getting someone who understands why a site succeeds or fails at every level. My dual background in structural architecture and digital engineering shapes how I approach every build, with precision, strategy, and structural integrity. I don't guess or vibe-code. I design, test, optimize, and ship.

I build full-stack SaaS platforms, AI agents, and voice automation systems for teams that need real production reliability, not demo-ware. With 5+ years shipping software in fintech and startup environments, I bring engineering discipline from systems that move real money (deposits, withdrawals, coin exchange) into the AI agent and automation space. That background matters: when your voice agent books an appointment or your workflow touches customer data, you want someone who has already built for correctness under pressure.

In the world of pixels, I wield the magic of digital experiences 🪄 I build scalable web applications using custom code and visual development platforms. With 80+ projects delivered, I help startups and businesses launch faster, operate efficiently, and scale with confidence. My focus is on turning ideas into functional, production-ready applications without unnecessary complexity. I have hands-on experience building applications with tools such as Bubble, WeWeb, Adalo, Draftbit, Softr, Webflow, and Framer. I work on dashboards, marketplaces, internal tools, and customer-facing platforms, with attention to clean logic, intuitive user interfaces, and systems that are easy to maintain and extend. For complex logic and AI integration, I leverage full-stack technologies including React.js, Node.js, Next.js, and PostgreSQL. I also utilize AI-assisted development tools like Claude Code, Lovable, v0, and Cursor to streamline workflows, generate clean code, and accelerate delivery. As projects grow in complexity, I extend applications using cloud services and backend integrations. I work with AWS services including S3, Lambda, API Gateway, and IAM to add secure file storage, serverless backend logic, and API-based functionality. Alongside application development, I work with JavaScript, Supabase, Xano, and API integrations to connect services, automate backend processes, and maintain reliable data flow across systems. This allows me to support projects beyond a single platform and adapt to a wide range of technical requirements. Over the years, I have contributed to projects ranging from early-stage MVPs to more advanced cloud-integrated systems. My approach is practical and goal-driven, choosing the right tools for each problem and building solutions that support real business needs. What I Can Help You With • Application development Building scalable digital products using modern visual development tools, React, and structured backend logic. • Cloud and backend extensions Extending applications with AWS-based storage, APIs, and serverless backend functionality as product needs grow. • API integrations and system connectivity Connecting platforms using REST APIs, webhooks, and secure authentication for seamless data exchange. • AI Integration & Automation Implementing AI agents, LangChain workflows, and automation using tools like Claude Code and Lovable. Why Work With Me • Clear communication and fast response times • Strong experience building real-world products (80+ projects) • Flexible approach across different platforms and project types • Cost-efficient solutions without sacrificing quality • Systems designed to grow as your product evolves If you are looking for a developer who can build today and scale tomorrow, I would be glad to help bring your product to life.
