Most backends survive the demo. Mine survive the traffic spike six months after launch. Full Stack Developer, 10+ years, still get a small kick out of watching a full-stack system handle its first real traffic spike without blinking, frontend and backend both holding up under real load. Fintech, logistics, healthcare, SaaS, different industries, same discipline: build it to survive contact with real users, not just pass a demo. I bring the same full-stack architecture rigor whether I'm leading a team or the sole full-stack engineer on a build, and whether I'm deep in backend logic or shipping a complete feature end to end. Track record: ⭐ 100% Job Success Score 🏆 10+ years of commercial full-stack development, Java/Spring Boot backend, React/Next.js frontend, one engineer owning both sides 🚀 30+ production systems delivered as a full-stack engineer: SaaS platforms, APIs, and complete web applications 👥 Led full-stack engineering teams of 10+ developers through full-cycle SaaS delivery 💰 Built a full-stack fintech platform processing $15M+ annually, backend and frontend 🚚 Scaled a full-stack logistics platform to 1.2M+ daily API requests through Redis optimization 📈 Delivered a full-stack SaaS MVP in 6 weeks that secured $500K+ in pre-seed funding 🏗️ Architected full-stack multi-tenant SaaS systems with role-based access and tenant data isolation ⚙️ Migrated monolithic Java applications to full-stack Spring Cloud microservices architecture 🔒 Built full-stack HIPAA-aware healthcare platforms and PCI-conscious payment systems 🔗 Designed webhook-driven and GraphQL API layers connecting third-party financial and business systems across the full stack 🤖 Integrated OpenAI and Claude APIs into full-stack production workflows for AI-powered features 🧠 Use AI coding tools like Claude Code and Cursor daily across the full stack, reviewing and owning every line before it ships What I actually deliver as a Full Stack Developer: - Complete full-stack builds across React, Next.js, TypeScript on the frontend and Java, Spring Boot, Node.js on the backend, so one full-stack engineer owns the whole feature, not just one layer - Full-stack backend architecture and API design in Java, Spring Boot, Spring Cloud, Spring Security, and Hibernate, with Kafka, Redis, and RabbitMQ brought in where scale genuinely demands it - Full-stack REST and GraphQL API development, webhook integrations, OAuth2 and JWT authentication, role-based access control, and audit logging for compliance-sensitive systems - Full-stack database design and query optimization across PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch - Full-stack cloud infrastructure and DevOps on AWS (EC2, S3, RDS, Lambda, ECS), Docker, Kubernetes, Terraform, Jenkins, and GitHub Actions CI/CD pipelines that actually get used - Full-stack production-grade integrations: Stripe, Plaid, QuickBooks, Twilio, Firebase, and OpenAI/Claude API work for AI-powered features - Clean, testable, maintainable full-stack code built on SOLID principles and TDD, not process for its own sake I've spent real time as a full-stack engineer inside fintech payment systems, HIPAA-aware healthcare platforms, real-time logistics tracking, multi-tenant SaaS products, CRM and ERP systems, and marketplace platforms, so by the time we've finished the first call, I usually already recognize the shape of the full-stack problem and where the architecture tends to get expensive if it's wrong from the start. I care about writing full-stack code that the next engineer, whether that's me in six months or someone else on your team, can actually read and extend without a walkthrough. I work well both as the sole full-stack engineer owning a build end to end and as part of a small full-stack team, comfortable stepping into an existing codebase or architecting something new from a blank repo, frontend and backend both. If you need a Full Stack Developer, Java Developer, Spring Boot Developer, or Backend Developer for a full-stack system that has to scale under real usage, let's talk about what you're building, just text me 🚀
