I am a Computer Engineer and I build end-to-end modern software solutions. I create high-performance web interfaces with Angular, React, Next.js, TypeScript, JavaScript (ES6+), HTML5 and CSS3/SCSS; scalable backend services with Node.js (Express.js) and C# (.NET Web API); and robust data layers with SQL (PostgreSQL) and MongoDB. I take on projects end to end, from requirements analysis and architectural design to SSR & SEO optimization, server setup and deployment. Some of my recent work: Data Center Infrastructure Management (DCIM) Platform: Development of sensor monitoring, asset management and operational dashboard screens in an enterprise-scale application made up of 10+ modules. Real-time data streaming and 4K display optimization on data-intensive screens using Angular, TypeScript, RxJS and Angular Signals. A dynamic UI engine that takes shape at runtime based on data from the backend, and complex configuration management with Dynamic Reactive Forms / FormArray. Unity UI Toolkit & WebGL Hybrid Monitoring Solution: In the data center project, developing Single Line Diagrams, Super Sensor and 2D monitoring components with Unity UI Toolkit (UXML/USS) and integrating them in real time into the Angular application via WebGL (JS Bridge). End-to-End E-Catalog, Appraisal and Management Platform (salihantik.com): A full-stack web application running in production, built for showcasing antique products and for collecting and managing appraisal requests. Angular, Angular Signals, SSR & SEO optimization, Node.js, Express.js and MongoDB infrastructure; JWT authentication, Zod data validation, a secure admin panel, per-visitor favorite/view tracking and Cloudinary image optimization. Running in production on Netlify and an Oracle Cloud VPS (Ubuntu, Nginx, PM2, SSL). Real-Time Trip Tracking and Notification Automation: An automation system that instantly scans TCDD trip and seat availability and sends a Telegram notification when a seat opens up. Designed as web automation with Node.js and Playwright, and in the second phase moved to direct API integration for high performance and to an uninterrupted cloud architecture backed by MongoDB. Corporate CV and Candidate Management System: A full-stack management application developed end to end with C#, .NET Web API, SQL (PostgreSQL) and React, covering the whole lifecycle from relational database design to RESTful API integration. On the corporate side, at Birtech Teknoloji I designed the frontend architecture of data-intensive enterprise monitoring and management systems and carried out performance optimizations of existing modules. Previously, at Bihl+Wiedemann, I took part in full-stack development in the .NET and React ecosystem. I graduated from the Computer Engineering department of Konya Technical University with a GPA of 3.59/4.00; I have a strong engineering foundation in data structures, object-oriented programming (OOP), design patterns and relational database optimization. What I can do: Web application, SaaS and admin panel (dashboard) development (Angular, React, Next.js, TypeScript, JavaScript, HTML5, CSS3/SCSS) Backend and RESTful API development (Node.js, Express.js, C#, .NET Web API, JWT, Zod) Database design and query optimization (SQL, PostgreSQL, MongoDB & Mongoose) Dynamic form structures and real-time data visualization (RxJS, Angular Signals, Dynamic Reactive Forms, Unity UI Toolkit & WebGL integration) Web automation, data scraping, bot and testing processes (Playwright, Node.js, Telegram Bot integrations) Corporate websites, e-catalogs and search engine optimization (Next.js & Angular SSR, technical SEO, fast load times and mobile/4K compatibility) Refactoring, performance improvement and deployment of existing projects (Google Cloud, Oracle Cloud, VPS, Ubuntu, Nginx, PM2, SSL, Netlify, Render) How I work: I develop in adherence to Clean Code principles, layered architecture (Controller/Service/Middleware/Model) and end-to-end type safety (TypeScript, Zod). I don't just leave code in a working state; I design it with an architecture that is readable, modular and ready for the project to grow. I deliver the entire infrastructure completely, from server configuration (Nginx, PM2, SSL) to the deployment process, leaving a sustainable structure that another developer can easily take over after me.
