I help companies turn complex or fragile software into systems that are stable, scalable, secure, and easier to maintain. With 20+ years of experience as a Solution Architect, Technical Lead, Head of Technology, and hands-on engineer, I work best on projects where the challenge is bigger than simply adding features. Clients typically bring me in when they need to: * Stabilize an MVP before real users or growth * Modernize a legacy Java/Node.js application * Redesign APIs, databases, or backend architecture * Improve performance, reliability, security, and maintainability * Build workflow-heavy SaaS, CRM, ERP, healthcare, fintech, or marketplace platforms * Integrate third-party systems, APIs, messaging, payments, or legacy software * Review an existing architecture before committing more budget * Fix access-control, audit-trail, RLS, or data-isolation problems * Move a product toward production readiness My core stack includes Java/Spring Boot, Node.js/TypeScript/NestJS, PostgreSQL, Supabase, Redis, Camunda/BPMN/DMN, REST APIs, AWS/GCP, Docker, Kubernetes, and CI/CD. Recent work includes healthcare platforms, regulated workflow systems, Supabase/PostgreSQL security hardening, Camunda process automation, hotel/PMS integrations, real-time communication systems, betting/gaming platforms, Web3 applications, and IoT/telematics servers. What clients usually get from me is not just code. I help identify the real technical risks, simplify the design where possible, make practical architecture decisions, and then implement the important parts cleanly. I am comfortable working with existing teams and codebases, reviewing work already done, mentoring developers, and taking ownership of difficult backend, database, integration, workflow, and architecture problems. If your product needs to be stabilized, scaled, secured, modernized, or taken from “working” to “production-ready,” I can help.
