Full-Stack Engineer
Category : Web development
I’m a full-stack software engineer with 5+ years of professional experience building production web applications with Java, Spring Boot, Vue.js, and PostgreSQL.
I currently work full-time on an enterprise ALM platform used by automotive, medical device, and aerospace companies, and I freelance on selected projects during evenings and weekends.
I can help with:
• Full-stack web applications built from scratch
• Spring Boot backends, REST APIs, authentication, validation, JPA/Hibernate
• Vue 3 frontends, SPAs, dashboards, and admin tools
• PostgreSQL database design and integration
• Bug fixes, refactors, and feature development in existing Java/Spring or Vue codebases
• Clean handover: documentation, tests, and maintainable code
What you can expect from me:
• Production-minded engineering, not quick hacks
• Clear communication and honest scoping
• Strong written technical English
• Experience working with complex enterprise systems
• Comfortable reading, understanding, and improving existing codebases
• Reliable delivery for well-defined projects
I’m new to Upwork, but not new to professional software development. My current rate is an introductory rate for my first few clients on the platform while I build my Upwork profile and collect honest reviews.
You can see my portfolio and case studies at solidcraft.dev.
Live demos at solidcraft.dev:
• Real-time order dashboard (open in two tabs to see WebSocket sync)
• Buggy app to fixed app, side by side (open DevTools, click "Fix All Bugs")
• RAG-powered PDF assistant (upload any PDF, ask it questions)
Send me your project brief and I’ll reply with a clear scope, realistic timeline, and fixed-price or hourly estimate.
