.NET, Blazor, performance, and security
Secure, stabilize, and improve business-critical .NET applications.
I'm a .NET Full-Stack Web Engineer specializing in Blazor, ASP.NET Core, SQL Server, Azure, performance optimization, and application security. I help businesses fix slow systems, assess exposed web applications, close security gaps, and ship software that performs reliably in production.
Backed by hands-on work across Black Magic Group, Scale Shore Consulting, ImaliBooks, and SuppTech Financial Services, plus Hack The Box Academy training with 95 targets compromised and a Top 10% ranking.
- Production experience with Blazor, ASP.NET Core, SQL Server, Azure, Docker, and Linux
- Proven work fixing SQL injection, user-role misconfiguration, and access control issues
- Strong security coverage in XSS, broken authentication, IDOR, XXE, SSRF, SSTI, CSRF, and API attack paths
Security training
Security credibility built on both production work and structured offensive training.
My application security work is not only practical on live systems. It is also reinforced by dedicated Hack The Box Academy training focused on modern web exploitation and defensive thinking.
Hack The Box Academy
Top 10% ranking
Tracked progress with 95 compromised targets and strong module completion in web application security.
- Cross-Site Scripting (XSS)
- Broken Authentication
- Web Attacks including IDOR and XXE
Advanced web security
Modern exploitation coverage
Training includes deeper web exploitation concepts that improve how I design and review production systems.
- Server-Side Attacks including SSRF, SSTI, and SSI
- Advanced XSS and CSRF Exploitation
- Modern Web Exploitation Techniques
API and web assessment
Security-first engineering mindset
That training supports the way I build .NET systems by helping me think more clearly about exposure, abuse paths, and failure points.
- Web Service and API Attacks
- API Attacks aligned to OWASP API Security Top 10
- Information Gathering and JavaScript Deobfuscation
Top services
Security and recovery services built for live .NET systems.
The strongest commercial fit is where a business already has a system in production and needs risk reduced quickly, weak spots identified clearly, and implementation handled by someone who can also fix the code.
Web application pentest
Assess web applications for the vulnerabilities that most often damage trust, expose data, or open the door to account abuse.
- XSS, broken authentication, IDOR, XXE, and file inclusion review
- Server-side attack coverage including SSRF, SSTI, and SSI
- Clear findings with practical remediation direction
API and authentication security assessment
Review APIs, roles, sessions, and access-control logic to catch the security weaknesses that often slip into real business applications.
- OWASP API Security-focused assessment
- Authentication and authorization review
- Support for SQL injection and unsafe input-handling remediation
Performance and production hardening
Improve the performance and resilience of production .NET systems after risk or bottlenecks have been identified.
- Slow query, rendering, and backend bottleneck diagnosis
- Safer releases across staging and production environments
- Clean .NET remediation work rather than report-only consulting
Featured project
KnoxApp
A contract Blazor engagement delivered with a strong focus on performance, security, and production reliability.
At Scale Shore Consulting, I joined the KnoxApp project as a contract Blazor developer, enhanced the UI, shipped additional features, communicated directly with the client, handled bugs, and improved both performance and security across staging and production.
- Improved load times and overall responsiveness in a live client-facing system
- Managed staging and production environments to support stable releases
- Implemented security improvements and handled urgent issues as they surfaced
Selected work
Experience across live business systems, not just isolated projects.
My background includes in-house and contract work across product delivery, application security, performance improvement, and production support.
Current role
Black Magic Group
Intermediate Software Developer working on tracking and asset management systems in production environments.
- Fixed SQL injection and role misconfiguration vulnerabilities
- Implemented Akka Streams to improve speed for truck event processing
- Leading work on tracking and asset management applications
Blazor platform work
ImaliBooks
Full-stack Blazor development across frontend, backend, storage, and application security.
- Built the site with Blazor and .NET Core Web API
- Worked with Azure Blob Storage and .NET Identity roles
- Implemented middleware, dependency injection, and production-ready security patterns
Earlier full-stack work
SuppTech Financial Services
Full-stack development work across MVC, React, SQL Server, Azure, and backend APIs.
- Used .NET MVC for full-stack development
- Built frontend work with React and backend APIs on .NET
- Gained exposure to microservices, Docker, local stack workflows, and Jira-based team delivery
Why clients hire me
Built on real production responsibility, backed by continued security training.
My experience spans contractor and in-house delivery, production issue resolution, application hardening, cloud deployment, and performance work across real business systems, with Hack The Box Academy reinforcing the security side of that work.
I've worked as a .NET engineer across Black Magic Group, Scale Shore Consulting, ImaliBooks, and SuppTech Financial Services, building with Blazor, ASP.NET Core, SQL Server, Azure, MVC, and React while supporting live systems and business-critical delivery.
I also train in web application security through Hack The Box Academy, where I currently rank in the Top 10% with 95 compromised targets and completed modules across XSS, broken authentication, server-side attacks, API security, and modern web exploitation. That gives me a stronger and more defensive approach to building software.
