Haris N.

I’m a Senior Full-Stack .NET Developer with 7+ years of experience building web applications, APIs, SaaS platforms, and AI-powered applications for startups and established businesses. I work with modern AI-assisted development tools and agentic workflows as part of my day-to-day engineering process. Tools such as Claude Code, Codex, GitHub Copilot, and Cursor help me move faster with code understanding, implementation, debugging, refactoring, and technical research while architecture, security, testing, code quality, and engineering decisions remain under my control. What I can help you with: .NET / ASP.NET Core — Web APIs, backend systems, SaaS and business applications Full-Stack Development — React, Next.js, JavaScript and responsive web applications AI Integration — AI-powered features, LLM/API integrations, AI assistants and automation API & Integrations — REST APIs, third-party services, authentication, payments and webhooks Databases — PostgreSQL, MySQL, MongoDB, Redis, database-driven applications, query optimization, performance improvements Architecture — Clean Architecture, DDD, Onion Architecture, 3-Tier, SOLID and design patterns Existing Applications — debugging, refactoring, optimization, modernization and new features I’m comfortable joining an existing codebase or building a project from scratch. I care about clean architecture, maintainable code, performance, security, and building software that can grow with the business. How I work: I ask the right questions before writing code, communicate early when something needs to be reconsidered, and focus on delivering solutions that work beyond the initial implementation. I bring a combination of hands-on development, architecture, product understanding, and technical ownership to projects with a focus on building reliable software that solves the actual business problem. I’d be glad to help turn your idea or existing product into a dependable, well-built solution.
