Hi, I’m Jerzon — a Full Stack Software Developer and Technical Consultant with 9 years of experience building, stabilizing, and modernizing production systems for businesses.
I specialize in backend-heavy applications, system integrations, and cloud-hosted platforms using ASP.NET Core, Angular, SQL Server, AWS, and WordPress. My work focuses on ensuring systems are not only functional, but reliable, maintainable, and scalable under real-world usage.
Over the years, I’ve worked across full application lifecycles — from building systems from scratch to improving legacy platforms that suffer from performance issues, poor architecture, or inconsistent implementations.
Core Areas of Expertise
• ASP.NET Core (Web API, MVC, Razor Pages)
• Angular (scalable single-page applications)
• SQL Server, Entity Framework Core, AWS RDS
• AWS Cloud Infrastructure (EC2, S3, RDS, deployments)
• CI/CD pipelines (GitHub Actions, Jenkins, Octopus Deploy)
• WordPress engineering (custom themes, plugins, integrations)
• System integration, API design, and automation workflows• Performance tuning, debugging, and legacy system refactoring
How I Approach Work
I operate at the system level — not just task execution.
Instead of only delivering features, I focus on:
* Identifying root causes of technical issues
* Reducing long-term maintenance overhead
* Improving system performance and stability
* Designing clean and predictable architecture
* Ensuring systems scale without breaking under pressure
This approach is especially valuable for teams dealing with legacy systems, fast-growing applications, or inconsistent codebases.
What I Typically Help Clients With
• Building robust backend systems and APIs
• Fixing performance bottlenecks and system instability
• Modernizing legacy applications into scalable architectures
• Designing and implementing cloud deployment pipelines
• Integrating third-party APIs and internal systems• Improving database structure and query performance
• Enhancing WordPress platforms for speed and maintainability
Working Style
Clients typically work with me because I bring structure, clarity, and accountability to technical delivery.
I’m comfortable working independently or within teams, and I ensure:
* Clear communication throughout the project
* Early identification of risks and edge cases
* Practical solutions over unnecessary complexity
* Code that is clean, maintainable, and production-ready
My goal is always to make systems more stable, efficient, and easier to evolve over time.
Availability
I’m currently open to select freelance and long-term engagements where quality, reliability, and technical depth are priorities.
If you’re looking for someone who can take ownership of complex systems and deliver stable engineering outcomes, I’d be glad to connect.
