Project details
Still running your business on spreadsheets, disconnected tools, and manual handoffs?
I build custom ERP and business automation systems on ASP.NET Core to consolidate your inventory, CRM, time tracking, and approval workflows into one connected system—instead of five tools that don't talk to each other.
What You Get:
Role-Based Access Control (RBAC): Secure data boundaries so team members only see what’s relevant to their roles.
Custom Reporting & Dashboards: Real-time insights built entirely around the specific KPIs and numbers you actually track.
Scalable Architecture: A clean code foundation designed so new modules can be seamlessly added later without requiring a costly rebuild.
Core Tech Stack:
Backend: ASP.NET Core, Entity Framework Core, C#
Database: Microsoft SQL Server
Cloud/Hosting: VPS/Azure
Why Work With Me?
You will work directly with a senior .NET backend engineer who scopes each module around your actual business workflow—not a rigid, generic template. Zero middle-men, zero agency handoffs, just clean architecture designed to help your business scale.

About Md. Ashraful
Senior .NET Backend Developer | ASP.NET Core, APIs & AI Integration
Dhaka, Bangladesh - 3:17 am local time
𝗦𝗲𝗻𝗶𝗼𝗿 .𝗡𝗘𝗧 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿 | ASP.NET Core | REST APIs | AI Integration
If your ASP.NET Core application is slow, difficult to scale, or constantly breaking in production, I can help.
I'm a Senior .NET Backend Engineer with 6+ years of experience building production-ready backend systems for SaaS, Property Technology, Ecommerce, Payments, and Enterprise Applications.
Unlike many freelancers, I don't just build features—I take ownership of the complete backend, from architecture and API design to deployment, optimization, and production support.
