💡 I help you fix backend issues fast, stabilize live systems, and build reliable APIs that work under real-world load.
💡 I also work on Java + Angular/TypeScript full-stack bugs, especially issues involving existing codebases, state handling, API flows, auth, and cross-platform app behavior.
💡 I fix rough MVPs and broken code produced by Claude, Codex, Cursor, and other AI agents: fragile flows, messy handoffs, weak auth, API bugs, browser-extension issues, and code that works in a demo but breaks in real use.
💡 I can also build focused MVPs/prototypes in hours when the scope is clear, then clean them up so they are maintainable.
With 15+ years of hands-on experience, I’ve worked across enterprise systems, production debugging, high-availability applications, and government-grade Java/Spring Boot platforms. I’m not just building features; I’m usually the person called when something is already live, complex, slow, or broken.
What I can do for you:
* Debug and fix backend issues quickly (APIs, async flows, database problems)
* Fix frontend issues in Angular, TypeScript and JavaScript (UI bugs, API integration issues, state handling)
* Fix AI-generated / Claude / Codex / Cursor code before handoff
* Clean up fragile MVPs and turn them into maintainable software
* Debug browser extension issues and extension-to-backend connection problems
* Optimize slow queries and improve performance (MySQL, SQL Server, Oracle)
* Build and improve REST APIs (Java Spring Boot, Node.js)
* Integrate third-party APIs (OAuth, OIDC, secure integrations)
* Stabilize production systems and reduce recurring issues
* Build focused MVPs and internal tools using Java, Node.js, Angular, APIs, and AI-assisted development
* Automate workflows using scripts and AI agents where it makes sense
* Set up and troubleshoot Linux-based environments (dev tools, services, remote access)
* Configure browser-based dev environments (code-server / VS Code in browser)
* Secure access using Cloudflare Tunnel or similar approaches (no port forwarding / VPN)
* Fix and enhance C# desktop applications, including UI controls and small DevExpress tasks
* I also handle structured document and data transformation work, including XML/schema-based outputs, PDF/Word-to-structured-data conversion, validation-driven formatting, and automation around repetitive document workflows. My approach is practical: understand the target schema, convert carefully, validate the output, and deliver clean files that are easy to review and maintain.
Tech I work with regularly:
* Backend: Java, Spring Boot, Node.js, Python (automation/scripts)
* Frontend: Angular, TypeScript, JavaScript, HTML/CSS
* Databases: MySQL, SQL Server, Oracle, Redis
* APIs: REST, SOAP, API integrations, authentication flows
* Reporting: JasperReports / Jaspersoft
Experience highlights:
* 6+ years at Upland Software on PowerSteering PPM, delivering 20+ product features and fixing 100+ defects in a mature enterprise product
* Lead Java/full-stack work on Dubai Government projects, including DubaiNow integrations and the Dubai Police Rain and Waterlogging Forecast System
* Architected or contributed to 20+ telecom and financial transaction systems before moving fully into remote enterprise product work
* Strong focus on debugging, performance tuning, and understanding complex existing systems quickly
I’m not here just to write code. I focus on solving problems, especially in systems that are already live and need careful handling.
If your system has an issue, your AI-built MVP needs cleanup, or you need someone who can jump in, understand it fast, and fix it properly, I can help.
