I provide a Node.js Backend Developer team that ships production-grade SaaS, APIs and platforms. 11,000+ hours worked, 50+ Node.js Backend Developer projects delivered, 100% Job Success Score, Top Rated Plus. As CEO I scope and own every Node.js Backend Developer engagement we sign. I study the brief, run discovery with founders, match the right engineers and stay accountable for delivery. My team owns the code - I never touch it. So when a brief lands for a Backend Engineer, an API Developer or a full stack software engineer, I scope it and the team builds it. Why hire my team: - 20+ years of Node.js Backend Developer, Full Stack Developer and SaaS Developer delivery - 200+ Node.js Backend Developer and SaaS Developer projects shipped - Long-term clients on retainers (3 - 10+ years) Our Node.js Backend Developer team designs services, REST and GraphQL APIs, queues and event pipelines that hold up under real production load. A NestJS Developer on the team treats Node as a serious production runtime and owns the heavy backend modules. Typical engagements: multi-tenant SaaS APIs, real-time platforms, billing flows, data pipelines, AI-backed services. Stack: Node.js, NestJS, ExpressJS, TypeScript, PostgreSQL, Redis, Elasticsearch, AWS, GCP, Docker, Kubernetes. Our Full Stack Developer team owns systems end-to-end - one team handling Node.js services, React frontends, data models and infra. A React Node pairing is our default shape - a React Node frontend on a NestJS Developer backend, with a nextjs developer on SEO-critical pages. We replace fragmented setups where a website developer, web developer and front end specialist were stitched together. Adjacent angles I present daily: full stack developer saas for B2B platforms, python full stack developer pairings for data and AI, full stack developer ai integrations, full stack developer react teams for SaaS dashboards, full stack developer shopify extensions, full stack web developer rebuilds of legacy SPAs, full stack ai saas developer engagements where LLM features must ship at production standard. Our SaaS Developer team helps founders ship multi-tenant SaaS and B2B platforms. A SaaS Developer engagement covers auth and RBAC, Stripe billing, observability, anti-abuse and event tracking the saas marketing team can use. The team has shipped a webflow developer saas pairing, a b2b saas booking system developer engagement, a ui ux designer saas pipeline, a saas explainer video flow in onboarding and a saas sales console wired into the backend. On the API side a dedicated API Developer track owns contracts and versioning. A REST API Developer designs the REST API Developer surface - resources, pagination, idempotency, webhooks - and the API Developer keeps SDKs and docs honest. A Backend Engineer owns the data layer; a second Backend Engineer covers queues and workers so the API never blocks on jobs. Cross-language coverage. A python developer track owns scraping, ETL and AI workflows. python nodejs migrations land here when teams consolidate dual stacks. flutter node.js and vue.js node.js setups join the core when mobile or admin SPAs need a reactive layer. A react developer pairing handles SaaS dashboards on the API. A wordpress developer or shopify developer hand-off covers CMS migrations. A mobile app developer pairing extends the SaaS into iOS and Android. Clients hire me when they need: - a Node.js Backend Developer team that owns architecture, APIs and scaling - a back end developer node.js bench for high-traffic SaaS - a Full Stack Developer team replacing 3 - 5 contractors with one coherent system - a SaaS Developer team fluent in multi-tenancy, auth, billing and RBAC - an API Developer and Backend Engineer pair for a clean, versioned REST API Developer surface - a full stack software developer practice with CEO-level discipline on roadmaps - a website developer hand-off backed by the team Recent work my team shipped: - Cybersecurity SaaS. Node.js, NestJS, PostgreSQL, Redis on GCP + Kubernetes. 170M+ req/week, 500 RPS peaks, 1M+ MAU. - Device Verification SaaS. Single backend powering web, Telegram bot and Developer API. 4K+ DAU, 1M+ checks, 80%+ via API. - Clinic Enterprise platform. React, Next.js, Laravel, Node.js, Redis, AWS. REST API, queues, RBAC, 1C and lab integrations. MVP in 4 months for 500 patients/day, 500K records. - E-commerce Data Pipeline SaaS. 50M+ products, per-partner parsers, dedup. Cloud cost cut ~9x at sub-second search across 300 - 500K DAU. - Multi-currency Voting SaaS. Wallets, Stripe top-ups, real-time vote locking over WebSockets. 2M+ users in 10 countries, $2.5M+ revenue. Reliable SaaS comes from deliberate design - that's what my Node.js Backend Developer, Full Stack Developer and SaaS Developer team focuses on. Need a Node.js Backend Developer team, a Full Stack Developer team or a SaaS Developer partner that delivers on time and stays long-term - let's talk.

I help businesses maintain and scale existing Laravel/PHP platforms and internal systems (15+ years in web development). Best fit: long-term development & technical ownership (3+ month engagements), not one-off tasks. Core areas: feature development, production support, performance optimization, refactoring, legacy modernization, API integrations. I work with a small in-house team (backend, frontend, QA) to provide reliable long-term support when needed. Recent relevant work: - Maintenance and modernization of legacy internal systems (stability, speed, technical debt reduction) - PIM / product data platforms managing 300,000+ SKUs with complex workflows - Complex multi-tenant SaaS platforms with admin dashboards, permissions, and background processing - AI-powered SaaS features (automation, intelligent search, data enrichment) - Enterprise integrations (Shopify, SAP, Salesforce, Stripe, internal APIs) Tech stack: PHP (Laravel/Symfony), Vue/React, SQL/MySQL/PostgreSQL/NoSQL, AWS, queues & background workers. Selected outcomes: - Page load time improved by 45% (2.2s → 1.2s) - API response time reduced from 300ms to under 150ms - Uptime improved to 99.99% for business-critical platforms - Automated test coverage increased to 90%+ Security & compliance awareness: encryption in transit/at rest, GDPR-ready systems, secure payment workflows (PCI principles). If you have an existing Laravel/PHP system that needs long-term ownership and steady development, let’s discuss your roadmap.

I am a Java developer with over 14 years of experience building full stack applications, enterprise systems, and SaaS platforms 🚀 My focus 🎯 is on using Java, Spring Boot, React.js, PostgreSQL, and AWS to deliver reliable, scalable software.

I am a Senior Next.js Developer focused on React, Node.js, and API-driven web applications. My main work is building custom web products where the frontend depends on clean architecture, reliable API integration, authentication, and real user workflows. I usually work on Next.js / React applications connected to existing backends, Node.js services, REST or GraphQL APIs, Firebase, CMS tools, and third-party integrations. I can help when you need a React developer or front-end developer who can do more than just build UI screens. I can take Figma designs, Bootstrap themes, existing prototypes, or legacy interfaces and turn them into production-ready Next.js / React pages connected to real data and backend logic. I also support full-stack Next.js and MERN-stack products when the project uses React, Node.js, Express.js, MongoDB, or a similar JavaScript-based stack. My backend work usually covers API integration, authentication flows, account logic, dashboards, ecommerce flows, admin panels, and integration with external services. Earlier in my career, I worked with WordPress, CMS-based websites, and classic web development projects. That experience helped me understand content structure, SEO-friendly pages, admin workflows, landing pages, and business websites. Today, my focus is custom development: Next.js applications, React frontends, full-stack Next.js products, SaaS platforms, ecommerce flows, marketplaces, customer portals, and web applications built around real product logic. Typical projects I can help with: - Next.js and React web application development - full-stack Next.js development with Node.js and Express.js - React developer / front-end developer work for existing products - REST API and GraphQL API integration - Firebase, Firestore, and Google Cloud Platform integrations - NextAuth and custom authentication flows - SaaS dashboards, customer portals, marketplaces, and ecommerce platforms - Strapi, headless CMS, and CMS-driven web products - Figma-to-Next.js or Bootstrap-to-Next.js implementation - frontend architecture, performance improvements, and code maintainability Tech I work with: Next.js, React, TypeScript, JavaScript, Node.js, Express.js, NestJS, MongoDB, PostgreSQL, RESTful API, GraphQL, Firebase, Firestore, Google Cloud Platform, NextAuth, Redux, Strapi, CMS integrations. I am comfortable joining an existing team, working directly with a CTO or founder, taking ownership of a product area, and moving features from backlog to release.
