I turn ambitious ideas into production-grade software, architecting cloud-native backends, polished full-stack products, and Agentic AI systems that don't just answer, but act. Certified Azure AI Engineer, relentless learner, and a writer who teaches what he builds.
Open for freelance projects
I'm a software engineer who lives at the intersection of enterprise engineering and applied AI. By day, I architect scalable Web APIs with .NET Core using Clean Architecture, CQRS and SOLID, and ship full-stack features with React, Angular and TypeScript on Azure.
By deeper curiosity, I build Agentic AI systems: LLM-powered solutions using CrewAI, LangChain and Retrieval-Augmented Generation, plus hands-on machine learning and deep learning models, from preprocessing to deployment. That blend won me 1st place at Verdentra's AI HackathonX, architecting a high-impact, AI-driven client solution.
Beyond code, I'm a technical writer with 50+ published articles, and a technical speaker running university workshops on AI and data science, because the best way to master something is to teach it. I'm also a freelancer, helping startups and businesses ship web apps, APIs and AI features.

First-place winner at Verdentra AI HackathonX. Architected and delivered a high-impact agentic AI solution for a real client use case, covering multi-agent orchestration, retrieval pipelines and enterprise-grade integration under hackathon pressure.
Production-style REST API built on .NET 8 with microservices design: clean separation, feedback-service domain, and API best practices. ⭐ 7 stars on GitHub.
Final-year research project (SLIIT): an AI-powered voice-assistant mobile app combining a Flutter client with a Python ML backend, where computer vision meets accessibility.
E-commerce server built as Spring Boot microservices, covering service decomposition, inter-service communication and API design on the JVM. ⭐ 3 stars on GitHub.
Deep-learning image classifier benchmarking four model architectures on plant-disease datasets, with training, evaluation and comparative analysis in Jupyter.
Open Data Protocol layered over MongoDB Atlas in ASP.NET Core, giving queryable REST endpoints with filtering, paging and projection out of the box.
I write about .NET, system design and the AI era of software engineering for 949+ followers on Medium.

Read on Medium ↗Beyond my full-time role, I take on select freelance projects. From a rough idea to a deployed, production-ready product, here is what I can build for you.
End-to-end web applications with React or Angular frontends and .NET, Spring Boot or Node.js backends. Responsive, tested and ready for real users.
Intelligent features that go beyond a chat window: RAG pipelines over your data, multi-agent automation with CrewAI and LangChain, and custom ML models.
Clean, well-documented REST APIs and microservices with solid database design on SQL or NoSQL. Built to scale and easy for other teams to integrate.
Get your product deployed and observable on Azure or AWS, with CI/CD pipelines, containers and monitoring, so releases are boring in the best way.
Developer-focused articles, tutorials and documentation that people actually read. 50+ published pieces on .NET, system design and AI, and I can write for your brand too.
Sessions that make complex topics click. I run university workshops and tech talks on AI, data science and modern engineering, and mentor aspiring developers.
