💡 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.

15+ years of commercial software development using Java/Python/React tech stacks both for big corporations and for startups in several domains: AI/ML, Finance/Trading, AdTech and others. I’ve been dealing with large scaled distributed and heavy loaded applications with thousands of concurrent users/transactions per second and processing several TB of user data daily. I specialize in backend multi-threaded applications but also have an extensive experience with web applications with complex UI logic. I'm fan of clean code, simple architectures and Test Driven Development (TDD) When a designing an application from scratch or fixing legacy one - I use OOP/OOD approaches for easy enhancements in the future and keep architecture as simple and flexible as possible which allows to minimize a technical debt of the whole project. My main goal is meeting client's business needs with an effective scalable architecture and good code quality (coding standards, unit-test coverage, etc).
