Role Summary

AAPNA Infotech is seeking an experienced .NET Desktop Applications Developer with strong hands-on experience in development and production support of desktop applications using .NET (WinForms/WPF), WCF services and SQL Server. The ideal candidate will be comfortable working across the full application lifecycle — from design and development to troubleshooting and post-production support — and will collaborate closely with QA, DevOps, product owners and global engineering teams.

Key Responsibilities

• Design, develop, and maintain desktop applications using .NET technologies (WinForms and/or WPF) following best practices for modularity, reusability, and maintainability.
• Design, implement, and consume WCF services for inter-process and distributed communication; maintain backward compatibility and secure endpoints.
• Develop and optimize SQL Server database schemas, stored procedures, views, and queries; perform data modeling and ensure data integrity.
• Provide L2/L3 production support — triage incidents, diagnose root causes, apply fixes or workarounds, and coordinate rollbacks and releases when needed.
• Troubleshoot application issues (crashes, memory leaks, performance bottlenecks), analyze logs, and implement fixes or performance tuning.
• Create and maintain technical documentation: design specs, runbooks, deployment guides, and post-incident reports.
• Collaborate with QA and Automation teams to ensure testability; support automation for desktop apps where applicable.
• Integrate applications into CI/CD workflows and participate in release management using Azure DevOps or equivalent tools.
• Work with source control (Git) and build tools (MSBuild, NuGet); manage dependencies and versioning.
• Participate in Agile/Scrum ceremonies; provide estimates, report progress, and highlight technical risks.
• Provide mentoring and knowledge transfer to junior developers and support engineers.
• Ensure security, compliance, and regulatory requirements are met for domain-specific applications.
• Communicate clearly with cross-functional stakeholders and provide timely status and incident updates.

Required (Must-have) Skills & Experience

• 3+ years professional experience building and supporting .NET desktop applications (WinForms and/or WPF).
• Strong C# expertise and object-oriented design principles.
• Hands-on experience designing, developing and consuming WCF services (bindings, behaviors, security).
• Solid experience with SQL Server: T-SQL, stored procedures, performance tuning, indexing, and data validation.
• Proven experience in production support: incident management, debugging, root-cause analysis, and hotfix deployment.
• Familiar with version control (Git) and build/dependency management (MSBuild, NuGet).
• Experience with Azure DevOps (pipelines, repos, work items) or similar CI/CD and ALM tools.
• Strong troubleshooting skills — memory profiling, exception analysis, log analysis, and performance diagnostics.
• Good understanding of networking basics, serialization, threading, and IPC patterns relevant to desktop apps.
• Excellent communication skills and ability to work in the evening shift (US shift/EST hours) with global teams.
• Strong problem-solving skills, attention to detail, and ability to work independently under pressure.
