What I'm looking for

I'm seeking a challenging position with a growth-oriented organization.

At Zapproach, I developed and maintained Zaccbox Retail and Zaccbox Legal, including an API Gateway and ERP backend using .NET 8.0, C#, Entity Framework, and PostgreSQL. I also built backend services for ERP microservices and RESTful APIs connecting ERP modules with Next.js applications.

On Zapproach's E-Wallet project, I developed and maintained a modular backend with .NET 9.0, C#, Entity Framework, and PostgreSQL. I worked on account and profile endpoints, payment-related email and QR code features, and the support ticket module.

At Atrsian Sofware Technology, I contributed to M Power, a hospitality and healthcare project, and worked on its architecture and coding. I implemented RabbitMQ messaging and Refit REST API integration, and contributed across requirements, testing, and deployment.

At Digisoft Solution, I developed modules for Owner Relation and worked on Encrypt Titan, covering email encryption, user and reseller management, licensing, and domain configuration. Earlier, at Techbit Solution Pvt Ltd., I worked on Home Front CRM, resolving client-reported issues and assisting senior developers with coding, testing, and documentation.
