Hi, I'm Joydev Chand πŸ‘‹

.NET Developer building backend systems with ASP.NET Core, EF Core & SQL Server. I like taking projects past the "it works on my machine" stage β€” clean architecture, proper auth, and tests that actually catch bugs.

πŸ“ Balasore, Odisha, India

🟒 Open to opportunities β€” actively looking for full-time .NET Developer roles

πŸ’Ό Background

Most recently worked as an Associate Software Engineer Intern at Bitlyze Technologies (Dec 2025 – June 2026), building a multi-module Conference Portal in ASP.NET Core MVC with RBAC across Admin, Faculty, and Student roles, plus an automated attendance-tracking module.

Currently sharpening my skills and building projects while looking for my next role.

πŸ› οΈ Tech Stack

C# .NET ASP.NET Core SQL Server Entity Framework JavaScript Git Swagger Postman

Core concepts: OOP Β· SOLID Β· Repository Pattern Β· Dependency Injection Β· REST API Design Β· async/await

πŸš€ Featured Projects

Multi-role REST API with 4-layer Clean Architecture, JWT auth, and an appointment state machine (Requested β†’ Confirmed β†’ Completed/Cancelled) using EF Core RowVersion tokens to prevent double-booking. 13 xUnit tests mock every repository β€” zero database dependency in the test suite.

3-role portal (Admin, Employer, Job Seeker) with JWT auth, MSSQL stored-procedure search with pagination and caching, and SendGrid email notifications on application status changes.

A learning project exploring core RLHF concepts β€” pairwise ranking, reward scoring, and dataset curation β€” inspired by how labs like Anthropic and OpenAI structure human-feedback pipelines for LLM alignment.
