18 Years of Engineering Excellence | AI-Augmented .NET Developer
I bridge the gap between deep-rooted architectural stability and the future of high-velocity development. With nearly two decades of experience across Direct Sales, EdTech, and enterprise sectors, I specialize in building scalable, mission-critical systems using the .NET ecosystem and Azure/AWS cloud.
I am a firm believer that the future of software belongs to the "AI-Augmented Developer." By deeply integrating GitHub Copilot and AI-driven workflows into my daily practice, I’ve accelerated the development lifecycle—drastically reducing boilerplate time, enhancing unit test coverage, and rapidly prototyping complex C# architectures without sacrificing the SOLID principles I’ve mastered over 18 years.
What I bring to your team:
- AI-Powered Velocity: Leveraging GitHub Copilot for faster refactoring, documentation, and TDD.
- Architectural Rigor: Deep expertise in DDD, CQRS, and Microservices to ensure systems aren't just fast, but resilient.
- Full-Cloud Mastery: Designing and deploying scalable environments across Azure or AWS.
🛠 Technical Ecosystem
- Core & Backend: .NET 8, C#, ASP.NET Core, Web API, GraphQL, Microservices, SQL Server.
- AI & Efficiency: GitHub Copilot (Advanced Prompt Engineering), GitHub Actions (CI/CD).
- Cloud & DevOps: Azure (App Services, Service Bus), AWS (Lambda, ECS, SQS, CDK), Docker, Kubernetes.
- Architecture: SOLID, DDD, CQRS, Event-Driven Systems, Unit Testing (Jest/xUnit).
- Frontend & Modern Web: React, TypeScript, Node.js, WebSockets.
- Legacy Modernization: Expert at transitioning WebForms/WSDL systems into modern REST/Cloud-native architectures.
Why Work With Me?
I don’t just write code; I solve business problems. Whether it’s consulting on a new startup or optimizing a legacy SQL environment, I focus on maintainable, elegant solutions that align with your bottom line.

I help companies design, build, and stabilize web platforms that actually hold up in production: fast, reliable, and easy to evolve.
Over the past 10+ years, I’ve worked across the full stack with Node.js, TypeScript, React/Vue, Golang and AWS, delivering applications that support real users and real revenue. My background ranges from early-stage MVPs to complex, long-lived systems.
What I do best:
- Full-stack web development
React / Vue frontends with clean, maintainable components
Node.js / TypeScript / Golang backends with clear architecture
RESTful APIs and WebSocket-based real-time features
- Backend & API engineering
Design and implementation of robust API layers
Authentication, authorization and multi-tenant setups
Performance tuning, observability, logging and error handling
- Refactoring & system improvement
Taking over existing codebases and making them stable, testable, and easier to work with
Improving performance, reliability, and structure without breaking the business
Planning technical roadmaps and “rescue” plans for struggling systems
- Cloud & infrastructure (AWS)
Deploying and running services (compute, DNS, basic networking)
Practical, simple setups that avoid unnecessary complexity and cost
-- Types of projects I’ve delivered
Emergency communication and network platforms
Real-time chat and messaging systems
IoT integrations and data pipelines
Digital publications and subscription platforms
VOIP-integrated services and internal tools
How I work:
Quality first: Every endpoint and feature is properly tested and considered in the context of the overall system.
Clear communication: I keep you informed with concise updates, trade-offs, and realistic options, not buzzwords.
Ownership mindset: I treat your project as if it were my own product, not just "tasks in a board."
If you need a developer who can both write solid code and think about the system as a whole, from architecture to delivery, I’d be happy to discuss your project and see if we’re a good fit.
