I'm a backend developer working mainly with Node.js, NestJS and PostgreSQL. I build APIs, integrations and backend systems, and I’m also comfortable jumping into an existing codebase to fix problems or add new functionality. A lot of my work starts with an existing product rather than a blank repository. Sometimes a new feature needs to be added, sometimes an external service has to be integrated, and sometimes something simply doesn't work the way it should. I can help with: - REST APIs and backend development - NestJS / Node.js / TypeScript applications - PostgreSQL and database design - third-party API integrations - payment integrations - Redis, queues and background jobs - WebSockets and real-time functionality - Docker and deployment - debugging and performance issues - refactoring existing backend code My usual stack is NestJS, Node.js, TypeScript, PostgreSQL, Redis and Docker. Depending on the project, I also work with AWS, RabbitMQ/SQS, WebSockets, Prisma, TypeORM and Drizzle. I care about keeping code understandable and maintainable. I don't like introducing another service, abstraction or dependency unless it actually solves a problem. I'm also an experienced WordPress/PHP developer. WordPress is where a large part of my freelance career started, and you'll find many WordPress projects and client reviews in my Upwork history. I still work with WordPress when a project needs custom development, WooCommerce, plugin/theme work, API integrations or debugging that goes beyond installing and configuring plugins. My backend experience is particularly useful for WordPress projects involving external APIs, custom business logic or integrations. If you're starting something new, I can help you design and build the backend. If you already have a project, I'm equally comfortable opening the codebase, figuring out how it works and getting to work without trying to rewrite everything from scratch. Tell me a little about the project and what you're trying to solve. I'll be happy to take a look.

My Full Stack Developer focus is CRM, ERP, admin systems and B2B platforms - Full Stack Developer builds with RBAC, audit trails and Stripe billing. Clients come to a Full Stack Developer instead of splitting a project between a Front End Developer shop and a Backend Developer contractor, so QA and deployment stay inside one Full Stack Developer workflow. The Full Stack Developer stack is React, Next.js, Vue, PHP, Node.js, MySQL and Redis, on AWS, GCP and Heroku infrastructure sized for peak loads up to 100K users per second. Adjacent Full Stack Developer tracks: Full Stack Web Developer rebuilds, Python Full Stack Developer pairings for data work, Full Stack Developer AI on a codebase already in production, and Full Stack Developer React funnels. My Front End Developer track is where a product stops looking like an internal tool - dashboards, admin panels, multi-tenant SaaS consoles and marketing funnels, with pages rendering in under 2 seconds. A Front End Developer React build is the default in a Full Stack Developer engagement: React with Next.js, Tailwind and Redux, plus Front End Developer Next.js server rendering when SEO carries the traffic. My Front End Developer also ships Vue 3 with Pinia when a project already runs a PHP backend. Clients searching for a Front End Web Developer or a React Developer want one Front End Developer who owns component architecture, state and API contracts. Front End Developer AI work grows every quarter: streaming responses, chat surfaces and agent panels in an app that already has users. My Backend Developer work carries the load underneath - REST and GraphQL APIs, queues, background jobs, reporting and integrations. A Node.js Backend Developer service is the usual answer when real-time traffic or webhook throughput matters, and a Backend Developer Nest.js structure keeps a growing API navigable. On the PHP side the same Backend Developer covers Laravel and custom PHP with MySQL, Redis and OpenSearch. Where a client wants a JavaScript backend end to end, backend NodeJS services sit behind the same Next.js frontend, and a Python Developer joins for data work and AI. My Backend Developer also inherits legacy systems: a WordPress Developer migration out of Gutenberg into a custom platform, an API that keeps answering while it gets replaced. Clients search by role, and the same engineers field all of them - a Full Stack Developer, a Backend Developer or a Software Developer on the server side, a Front End Developer, React Developer or Vue.js Developer on the client side, and PHP Developer, CRM Developer or ERP Developer profiles. When a build needs a Mobile App Developer alongside the web product, my engineers ship the app on the same Full Stack Developer API. As COO I oversee every Full Stack Developer engagement - the discovery, matching the right Full Stack Developer engineers, the commercial side. My Front End Developer and Backend Developer engineers own the code, and they say I am full stack developer with more than 12 years of experience - my main skill is full stack development. Clients hire me for Full Stack Developer work when they need: - a Full Stack Developer who owns frontend, backend, infrastructure and deployment - a Front End Developer for a dashboard, console or funnel that has to feel fast - a Backend Developer for APIs, integrations and reporting that stay predictable under load Recent Full Stack Developer work I shipped: - Built a Full Stack Developer identity-verification SaaS on a PHP API with Node.js real-time on MySQL and Redis - 4K+ DAU, 1M+ checks through a public Developer API. - Scaled a multi-currency voting SaaS to 2M+ users across 10 countries with vote locking and Stripe payouts, $2.5M+ revenue. - Grew a B2B luxury asset marketplace with 15 engineers - React, Next.js, PostgreSQL, OpenSearch, Stripe - to 26K MAU, 75% MoM growth, 25% engagement. - Delivered a Full Stack Developer medical-center ERP with registration, cashier, doctor and lab modules for 60 staff and 500 patients a day. Need a Full Stack Developer who covers the Front End Developer and Backend Developer sides and stays long-term - let's talk.
