$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.

$40M+ in Client Revenue | Top-Rated Plus | 100% Job Success | 10+ Years on Upwork I help companies build, migrate, and scale reliable commerce systems. I work as a Shopify Developer, Shopify migration specialist, and eCommerce Development expert, focusing on stable architecture, performance, and long-term growth rather than short-term fixes, fragile plugins, or rushed implementations. Clients engage me as a Shopify Developer for Shopify migration and eCommerce Development when they need predictable delivery and clean technical execution. My work includes full Shopify builds, advanced Shopify migration projects, and custom eCommerce Development for businesses that have outgrown basic templates, rigid themes, or plugin-heavy setups that no longer scale. I regularly support Shopify migration and eCommerce Development initiatives as a Shopify Developer during audits, rebuilds, replatforming projects, and long-term optimization work. A major part of my experience is Shopify migration and eCommerce Development from platforms such as wordpress, woocommerce, and bigcommerce. I regularly deliver wordpress migration and bigcommerce migration projects, handling products, customers, orders, historical data, URLs, redirects, and SEO continuity. As a senior Shopify Developer focused on Shopify migration and eCommerce Development, I approach migrations as structured engineering projects, not simple exports, one-click tools, or automated scripts without validation. Beyond standard Shopify stores, I also design and build custom ecommerce platforms and marketplace systems. These include bespoke ecommerce website solutions, multi-vendor marketplaces, and commerce-related web applications. In these cases, eCommerce Development goes far beyond themes, requiring custom workflows, platform extensions, backend services, and well-defined data models. From a technical perspective, I work as a Full Stack Developer, using React, Next.js, Medusa.js, Node.js, and Python. This enables advanced implementations such as headless storefronts, custom checkout flows, internal dashboards, marketplace logic, admin tools, and platform integrations, all aligned with Shopify migration requirements and long-term eCommerce Development goals. As a Shopify developer, I handle custom themes, shopify app integrations, advanced Liquid logic, and performance optimization. shopify speed, Core Web Vitals, accessibility, and maintainable code are always priorities. Clients looking for a shopify designer benefit from my ability to combine UX, performance, and engineering within a single Shopify Developer and eCommerce Development engagement. My eCommerce Development experience includes subscription businesses, shopify dropshipping, content-driven ecommerce website builds, B2B storefronts, and scalable marketplace platforms. I often collaborate with web developer and wordpress developer teams during Shopify migration projects, ensuring clean handovers, documented systems, and maintainable codebases that internal teams can extend safely. Many clients come to me specifically for Shopify migration and eCommerce Development planning before any build starts. In these cases, my role as a Shopify Developer includes technical discovery, architecture decisions, data validation strategy, risk assessment, and execution planning. This upfront work helps avoid replatforming mistakes and ensures Shopify migration efforts support real operational and revenue goals. I’m frequently brought in as a Shopify Developer to audit existing Shopify stores, review shopify app usage, identify performance bottlenecks, assess technical debt, and define a clear roadmap for continued eCommerce Development. This is especially valuable for teams preparing for scale, international expansion, multi-store setups, or complex Shopify migration scenarios involving external systems. For long-term engagements, I often stay involved as a Shopify Developer or Full Stack Developer and eCommerce Development partner, supporting ongoing improvements, feature expansion, platform evolution, and custom development as business needs change over time. What working with me typically looks like: - Senior ownership from a Shopify Developer - Structured Shopify migration planning and execution - Custom eCommerce Development and marketplace builds - Full Stack Developer support when a Shopify Developer alone is not enough - Long-term focus on scalability, performance, and maintainability Depending on scope, I either: - work directly as a Shopify Developer, Shopify migration specialist, Full Stack Developer and eCommerce Development expert, or - involve additional specialists from the team when more capacity is required If you’re looking for a Shopify Developer for Shopify migration or a Full Stack Developer for eCommerce Development, including custom ecommerce platforms, advanced ecommerce website extensions, or marketplace platforms, I’m happy to review your setup and discuss next steps.
