Full Stack Software Engineer | Web, Mobile, and .NET Core

I’m a full stack engineer who enjoys turning ideas into reliable, production‑ready software. I like understanding how systems fit together, designing APIs that feel clean to use, and building interfaces that stay simple even as the underlying logic grows. I care about clarity, maintainability, and creating software that feels intentional from the backend architecture to the final UI details.

• Frontend: React, Angular and Vue with component‑driven architecture and clean UI patterns
• Backend: C, C++, C#, .NET Core, Python, PHP for building maintainable APIs and services
• Mobile: Kotlin with Jetpack Compose and Swift with SwiftUI for modern native app development
• Architecture: clean architecture, modular design, dependency injection, REST API design
• Data: SQL, EF Core, LINQ, and offline‑first storage using Room, SQLite, and Core Data
• DevOps: GitHub Actions, Docker, Podman, CI/CD pipelines for automated builds and deployments
• Performance & Maintainability: efficient state management, caching strategies, scalable and readable code

• SpaceX Launch Tracker: full stack Blazor Server application that displays real time upcoming SpaceX launches using the Launch Library 2 API, built with ASP.NET Core and TailwindCSS
• Quote of the Day (Angular): standalone components, signals, clean UI, no repeat logic
• CareerFlow (Android): AI powered career advisor built with Kotlin, Jetpack Compose, and Google Gemini 1.5 Flash, providing real time personalized career guidance based on user interests and skills
• CryptoPulse (iOS): real time cryptocurrency tracker built with SwiftUI, SwiftData, Charts, and the CoinGecko API, featuring watchlists, sparkline charts, offline support, and a clean responsive interface
• GoTesty (Web + Desktop): lightweight API testing tool built with Go, Wails, React, and Tailwind, offering a fast, minimal interface for sending requests and inspecting responses
• Mini Shell (C) — POSIX‑style shell implemented in C with job control, piping, redirection, and signal handling

• Web apps using Angular, React, Vue, TypeScript, and clean component architecture
• Backend services with .NET Core, EF Core, Python, and container ready APIs
• Mobile apps for Android and iOS using Kotlin, Swift, and offline first patterns
• Automation and tooling to streamline workflows
• Minimal UI and UX with intentional interactions

• Built and maintained Android and iOS apps with modern Kotlin, Jetpack Compose, Swift, and SwiftUI
• Integrated OAuth, REST APIs, analytics, and push notifications with FCM and APNs
• Implemented offline storage with Room, SQLite, and Core Data
• Delivered stable and maintainable architectures for production apps

• Designed and built RESTful APIs with ASP.NET Core
• Implemented EF Core, LINQ, migrations, and clean data layers
• Containerized services using Docker and Podman
• Built CI and CD pipelines with GitHub Actions

• Built CLI tools and utilities using C and C++ with a focus on performance and reliability
• Implemented POSIX‑style features including file I/O, process control, and signal handling
• Developed data‑driven components using custom data structures and memory‑safe patterns
• Created maintainable, testable modules for low‑level workflows and tooling

• Angular standalone architecture
• Vue 3 composition patterns
• Clean .NET Core service design
