You will get a clean architecture .NET Core API in 7 Days
Project details
I'm a backend developer and .NET Core architect with strong experience designing clean, maintainable, and scalable REST APIs. Whether you're building a new product, modernizing legacy systems, or creating a modular foundation for future growth, I can help you set up your backend the right way.
I’ve worked with startups, internal platform teams, and product owners delivering reusable backend templates, modular architecture, and developer-friendly APIs built with long-term maintainability in mind.
Clean Architecture Expertise:
• Layered architecture (API, Service, Data)
• DTO mapping, validation, and error handling
• JWT authentication & role-based access
• Swagger/OpenAPI documentation
• Soft delete & audit field logic
• Base service + entity abstraction for fast expansion
• Dockerized local development environments
Tech Stack:
.NET Core, Entity Framework Core, AutoMapper, PostgreSQL, Docker, Swagger
Let’s build a backend that’s clean, fast, and ready to grow with your product.
Feel free to reach out with any questions or for a custom scope!

+$50 - $250About Veysi Furkan
Software Engineer - Backend & Data | .NET, Python, RabbitMQ, Spark
Istanbul, Turkey - 2:56 pm local time
My main focus is building reliable, scalable systems with .NET and Python, but my work usually goes beyond a single layer. I’ve built APIs, microservices, queue-based architectures, ETL pipelines, reporting systems, internal tools, and frontend dashboards that turn complex data into usable products.
I work comfortably with ASP.NET Core, FastAPI, RabbitMQ/AMQP-based systems, PostgreSQL, MSSQL, Redis, Docker, and AWS. On the data side, I’ve worked with Python, Pandas, NumPy, Scala, and Spark for data processing, transformation, reporting, and pipeline development. When a project needs frontend support, I can also handle dashboard and admin-style interfaces with Vue.js and data visualization tools.
Over the years, I’ve worked on projects involving factory analytics, IoT-style data flows, internal operational tools, reporting platforms, queue-based integrations, and full-stack systems built from scratch. I’ve helped teams improve system reliability, reduce downtime, clean up unstable architectures, and turn unclear technical needs into maintainable solutions.
What I usually help clients with:
- Backend API development with .NET Core / ASP.NET Core and Python / FastAPI
- Microservices and distributed system design
- RabbitMQ, AMQP-based communication, event-driven flows, and background job processing
- ETL pipelines, reporting systems, and data transformation workflows
- Spark / Scala or Pandas / NumPy based data processing
- PostgreSQL / MSSQL database design and backend business logic
- Dashboard and admin panel development for operational visibility
- System integrations, performance improvements, and production-ready architecture
How I work:
- I focus on building systems that are clean, practical, and maintainable
- I care about delivery speed, but not at the cost of long-term stability
- I can take ownership from architecture to deployment
- I communicate clearly and try to be a real technical partner, not just someone writing tickets
My background is strongest in backend engineering, but I’m at my best in projects where backend, data, and product behavior need to work together properly.
If you need someone who can design the architecture, build the core system, handle integrations, and make the data actually useful on the product side, I’d be glad to help.
Steps for completing your project
After purchasing the project, send requirements so Veysi Furkan can start the project.
Delivery time starts when Veysi Furkan receives requirements from you.
Veysi Furkan works on your project following the steps below.
Revisions may occur after the delivery date.
Initial Discussion & Requirement Clarification
Once you reach out with your project idea, I’ll review your needs and clarify any initial questions. If needed, I’ll ask for additional context to fully understand your domain, data models, and architectural expectations.
Optional Online Meeting (If Needed)
If the project is complex or if you'd prefer a real-time discussion, we can schedule a quick video or audio call to align on expectations, define the API scope, entity behaviors, and long-term goals for the system.
