Thrissur, India - 8:29 am local time
My core expertise includes:
• C#, .NET, ASP.NET Core & Web API
• REST API development & third-party integrations
• SQL Server, complex queries & stored procedures
• ASP.NET Web Forms & legacy application modernization
• API authentication, validation & data integration
• Bug fixing, troubleshooting & performance improvement
• Insurance, ERP & business application development
I have hands-on experience developing solutions for insurance quotation, premium calculation, underwriting, policy issuance, member management, payment workflows and data-sharing integrations. I also have experience working with Open Finance APIs and integrating systems across multiple vendors and platforms.
My background in application support has given me strong troubleshooting and client communication skills. I can understand both the technical problem and the business requirement, which helps me deliver practical solutions instead of just writing code.
Whether you need a new .NET API, SQL/database work, third-party integration, an existing application fixed, or a legacy ASP.NET system enhanced, I can help take it from requirement analysis through development, testing and implementation.
