$100M+ in Client Revenue | Expert-Vetted (Top 1% Upwork) | 240+ Projects | 100% Job Success | 10+ Years on Upwork I’m a Full Stack Developer, SaaS Developer and Backend Developer focused on building production-ready software that holds up under real-world usage. My work sits at the intersection of software developer, web developer, and SaaS platform builder, with a strong backend-first mindset and deep attention to scalability, performance, and long-term maintainability. As a Full Stack Developer, I take ownership of systems end-to-end, pairing robust backend architecture with clean, modern interfaces. My frontend work is typically React-based and I often collaborate with or replace traditional React developer or web developer setups by owning both frontend and backend in a single, coherent system. While I’ve previously worked as a WordPress developer and integrated WordPress-based sites into custom platforms, my current focus is on custom SaaS and API-driven systems rather than CMS-centric builds. As a SaaS Developer, I help companies design, build and scale SaaS products, internal tools and API-driven web applications intended for long-term use. My experience as both a Backend Developer and software developer allows me to think beyond features and focus on architecture, reliability and operational stability from day one. Many of the platforms I build support internal teams, customer dashboards and multi-role workflows where permissions, data integrity and business rules are critical. In my day-to-day work as a Backend Developer, I design and implement backend services, APIs and data models that power SaaS platforms, complex web applications and mobile-connected systems. I regularly work with Node.js and Python, drawing on my background as a Python developer to build scalable services, background jobs and asynchronous workflows that perform reliably in production. As a Full Stack Developer, I ensure these backend systems integrate cleanly with frontend applications, mobile extensions and third-party APIs. When required, I support frontend and mobile app developer workflows using React and React Native. This end-to-end ownership is a key reason clients bring me in as a Full Stack Developer rather than splitting work across multiple roles. A significant portion of my work as a SaaS Developer and Backend Developer involves building internal platforms, dashboards and API-first systems that integrate external services. In these projects, I often collaborate closely with product, growth, or analytics teams, including teams focused on SaaS marketing by designing clean data pipelines, event tracking and backend logic that supports experimentation, reporting and lifecycle insights. When projects require AI-powered functionality, I bring hands-on experience integrating AI into backend systems. While my primary role remains Full Stack Developer and Backend Developer, I regularly implement AI-enabled workflows, data processing pipelines and LLM-driven features inside SaaS platforms. This allows me, as a SaaS Developer, to deliver AI functionality that is reliable, observable and cost-controlled rather than experimental. Clients typically work with me when they need: - a Full Stack Developer who can own frontend and backend - a SaaS Developer who understands long-term scalability constraints - a Backend Developer experienced with real production systems - mobile app developer and React developer experience as a software developer - backend services built with Node.js or Python by an experienced Python developer - web applications with complex workflows and business rules from a senior web developer - API-driven architectures and third-party integrations - SaaS platforms designed to support growth, analytics and SaaS marketing data needs - MVPs that can realistically evolve into long-term SaaS products A large part of my work as a Full Stack Developer, SaaS Developer and Backend Developer focuses on: - multi-role dashboards and internal tools - authentication, authorization and permissions - API-first backend system design - integrations with external platforms, including legacy CMS or WordPress-based systems when required My core work as a Backend Developer and Full Stack Developer covers: - backend services built with Node.js and Python - APIs, background jobs and integrations - databases such as PostgreSQL - modern stacks using tools like Supabase - AI-enabled backend features where they add real business value I regularly work on MVP builds and early-stage products as a SaaS Developer, with strong focus on solid backend foundations, sensible scaling paths and avoiding short-lived prototypes. Based on scope and timing, I work hands-on as a Full Stack Developer, SaaS Developer and Backend Developer and when useful, involve specialists from my team. Long-term results come from clarity and intentional system design. I focus on delivering software that teams can confidently run, maintain and scale.

Slow Magento store, failed Shopify migration, broken checkout, low conversion rate, or an eCommerce website that looks good but does not sell? Or are you ready to add AI to your store – AI search, AI recommendations, an AI chatbot, AI automation – and need a developer who can actually ship it? I help online stores fix, optimize, migrate, scale, and AI-enable Magento 2, Adobe Commerce, Shopify, Shopify Plus, WooCommerce, and WordPress eCommerce websites, with a focus on AI development, speed, stability, UX, conversion rate optimization, technical SEO, and long-term growth. I am the founder and CEO of MageCloud, an eCommerce and AI development agency with 17+ years of experience in Magento development, Shopify development, WooCommerce development, eCommerce CRO, AI integration, custom integrations, and performance optimization. On Upwork, I have earned $2M+, completed 275+ jobs, maintained 100% Job Success, and achieved Top Rated Plus status. Clients hire me when they need a senior eCommerce and AI developer who understands both the technical side and the business impact behind it. I can help you with: • AI development, AI integration, and AI workflow automation for eCommerce stores • AI chatbots, AI assistants, AI-powered search, semantic search, vector search, RAG, and AI personalization • LLM integration (OpenAI / ChatGPT, Claude, and others), embeddings, custom AI agents, and AI API integration • Generative AI for product descriptions, content, and catalog automation; AI-driven CRO and predictive analytics • Magento 2 and Adobe Commerce development, upgrades, custom modules, Hyvä theme work, and checkout fixes • Shopify and Shopify Plus development, store optimization, theme customization, and app integration • WooCommerce and WordPress eCommerce development, plugin integration, and performance improvements • Magento to Shopify migration, Shopify migration, WooCommerce migration, and platform migration planning • eCommerce audit, Magento audit, Shopify audit, WooCommerce audit, AI readiness audit, and technical roadmap • Speed optimization, Core Web Vitals improvement, performance optimization, and technical SEO • Checkout, product page, cart, and UX/UI optimization, and eCommerce CRO • API integration, custom integrations, payment, shipping, ERP, CRM, AI integration, and third-party tools • Rescue projects after failed development, unstable code, broken checkout, slow performance, or technical debt • Long-term Magento, Shopify, WooCommerce, and AI feature support, plus eCommerce growth support My work is not limited to writing code. I look at the full eCommerce picture: how your store performs, where users drop off, what creates friction at checkout, how product pages convert, how stable your integrations are, where AI can remove manual work or lift conversion, and which decisions help your business scale without adding technical debt. Many clients come to me with problems like: • "Our Magento 2 store is too slow." • "Our Shopify store gets traffic but does not convert." • "Our checkout is broken or losing revenue." • "Our migration from Magento to Shopify feels risky." • "We want to add AI but do not know where to start." • "We need an AI chatbot or AI search that actually improves conversion." • "Our current developer disappeared or left technical debt." • "We need a senior Magento, Shopify, or AI developer who can own the project." That is exactly where I can help. As an eCommerce consultant, AI developer, and founder of MageCloud, I can work as an individual senior specialist or bring in a reliable team of developers, AI developers, designers, QA specialists, and project managers when needed. My approach is roadmap-first. Rather than diving straight into development, I start by identifying the real priorities: what needs fixing first, what can improve conversion rate, where AI adds real value (and where it doesn't), what reduces risk, and what delivers the highest ROI for the store. Why clients work with me: • $2M+ earned on Upwork, 275+ jobs, 100% Job Success, Top Rated Plus • 17+ years in eCommerce development • Magento, Magento 2, Adobe Commerce, Shopify, Shopify Plus, WooCommerce, and WordPress experience • AI development, AI integration, LLM integration, and AI automation for eCommerce • Strong focus on CRO, technical SEO, performance optimization, and long-term support • Complex stores, custom integrations, AI features, rescue projects, migrations, and scalable systems If your Magento, Shopify, WooCommerce, or Adobe Commerce website has technical issues, low conversion, unstable integrations, a risky migration, a failed development project, or an AI feature you want built right, send me a short description of your store, current problem, and business goal. I'll help you define the best next step, whether that's an eCommerce audit, a rescue project, a Shopify, WooCommerce, or Magento migration, CRO, a custom integration, or AI development.

I’m a SaaS Developer and Full Stack Developer with a passion for creating scalable SaaS products, MVPs, and business applications that tackle real operational problems. For over 8 years, I’ve helped startups, founders, and businesses design, build, and scale software products ranging from early-stage MVPs to production-ready SaaS platforms used by real customers. My work combines strong full-stack development expertise with practical AI integration, allowing companies to automate workflows, improve user experiences, and create new revenue opportunities. As a SaaS Developer, I build systems designed for long-term growth rather than short-term prototypes. Every project is developed with scalability, maintainability, and business objectives in mind. Whether building a customer-facing SaaS platform, an internal business tool, or an AI-powered application, I focus on creating solutions that continue to deliver value as the business grows. As a Full Stack Developer, I take ownership of projects from frontend to backend. I build modern web applications using React, Next.js, Node.js, PostgreSQL, Firebase, and cloud infrastructure. This end-to-end ownership allows me to deliver consistent user experiences while ensuring backend systems remain secure, scalable, and easy to maintain. A significant part of my work involves helping businesses launch MVPs quickly while establishing a solid technical foundation for future development. Rather than building throwaway prototypes, I focus on creating MVPs that can evolve into successful long-term SaaS products. AI integration has become a core part of many projects I deliver. I regularly implement AI-powered features using OpenAI and modern LLM technologies, including: - AI assistants and chat interfaces - Workflow automation systems - Intelligent content generation - AI-powered search and recommendations - Real-time voice and conversational applications - Custom AI features embedded directly into SaaS products As a Backend Developer, I design APIs, databases, integrations, and automation workflows that support complex business requirements. I frequently build systems that connect multiple services and automate repetitive processes, helping companies reduce manual work and improve operational efficiency. Many of the SaaS platforms and business applications I develop include: - Multi-role dashboards and administration panels - Customer portals and self-service platforms - Subscription and payment systems - Internal business tools and workflow automation - CRM and third-party service integrations - Maps, location, and geospatial applications - Reporting and analytics dashboards Clients typically work with me when they need: - SaaS Developer who understands both product and technology - Full Stack Developer who can own the entire application - AI Developer who can integrate OpenAI and LLM technologies into existing or new products - build MVPs without sacrificing future scalability - technical partner who communicates clearly and focuses on business outcomes My primary technology stack: React.js, Next.js, Node.js, TS, PostgreSQL, Firebase, OpenAI API, AWS/Vercel, REST APIs, WebSockets. Clients usually come to me when they need someone who can take ownership of a project from start to finish, communicate clearly, and think beyond just writing code. Whether it's building a new SaaS product, adding AI functionality, or improving an existing platform, I focus on creating solutions that are reliable, maintainable, and aligned with business goals. I enjoy working with founders, startups, and growing businesses that need a technical partner they can rely on for the long term. If you're looking for someone to help build, launch, or scale your next SaaS product, I'd be happy to chat. 👨‍💻 Working from a Home Office :)
