🚀 I build scalable backend systems and full-stack applications for SaaS platforms, startups, and enterprises — with 5+ years shipping production Java / Spring Boot systems, and hands-on MERN stack experience when projects call for a JavaScript-based full-stack build. I currently work as a Senior Software Engineer on Xcelerate, a microservices-based SaaS platform for restoration companies, where I develop and maintain 20+ Spring Boot microservices, build real-time messaging systems, and integrate third-party platforms like QuickBooks, RingCentral, Zapier, and Encircle. What I can help you build: ✔ Java & Spring Boot backend systems ✔ Microservices architecture & REST APIs ✔ MERN stack applications (MongoDB, Express, React, Node.js) ✔ Third-party integrations (QuickBooks, Stripe, Twilio, Zapier, RingCentral) ✔ Cloud deployments — AWS, Azure, GCP ✔ CI/CD pipelines (Jenkins, GitHub Actions), Docker ✔ Database design & query optimization (PostgreSQL, MySQL, MongoDB) ✔ Legacy system modernization (Java 8 → Java 21 migrations) Highlights: Led backend development across 20+ microservices for Xcelerate, a live SaaS platform for restoration companies Migrated infrastructure from VMs to Azure App Services, implementing Azure Front Door for traffic routing and load balancing Built WS Glam, a full-stack e-commerce platform from scratch — frontend, backend, admin panel, payment integration, and role-based access control Integrated Stripe subscription billing for Remojo and overhauled its backend architecture for scale Built a custom AML (Anti-Money Laundering) system from scratch, including case management tools and fraud detection workflows I think in terms of failure modes before I write code — what happens when a webhook fires twice, when an API rate-limits mid-sync, when a migration needs to run without downtime. I communicate proactively and hand off production-ready code with documentation to match. Let's talk about what you're building — I'll give you a straight technical assessment and a clear path forward.
