Integration Specialist / Full Stack Developer

As an Integration Specialist / Full Stack Developer at our company, your role will involve designing, developing, and maintaining backend APIs using .NET Core / C#. You will be responsible for building and integrating REST and SOAP-based services, implementing file-based integrations, working with various databases, handling data serialization/deserialization, and ensuring robust error handling and logging. Additionally, you will automate processes, manage version control and CI/CD pipelines, develop front-end interfaces, implement offline-first functionality for mobile apps, and collaborate with cross-functional teams or handle full project ownership. Key Responsibilities: - Design, develop, and maintain backend APIs using .NET Core / C#. - Build and integrate REST and SOAP-based services (JSON, XML, OAuth2, JWT, API Key). - Implement file-based integrations (Flat file, CSV, Excel, XML, JSON) and manage FTP/SFTP transfers. - Work with databases such as MSSQL, PostgreSQL, Oracle, and SQLite, including writing queries, stored procedures, and using ADO.NET. - Handle data serialization/deserialization using Newtonsoft.Json or System.Text.Json. - Implement robust error handling and logging with Serilog, NLog, or log4net. - Automate and schedule processes using Quartz.NET, Hangfire, or Windows Task Scheduler. - Manage version control and CI/CD pipelines via Git and Azure DevOps. - Develop front-end interfaces with React and React Native ensuring responsive, modular UI. - Implement offline-first functionality for mobile apps (sync logic, caching, etc.). - Collaborate with cross-functional teams or independently handle full project ownership. - Utilize AI-assisted development tools (e.g., Cursor, GitHub Copilot, Claude Code) to enhance productivity. - Apply integration best practices including middleware, API gateways, and optionally message queues (MSMQ, RabbitMQ). - Ensure scalability, security, and performance in all deliverables. Key Skills & Technologies: - Backend: .NET Core, C#, REST/SOAP APIs, WCF, ADO.NET - Frontend: React, React Native - Databases: MSSQL, PostgreSQL, Oracle, SQLite - Tools: Git, Azure DevOps, Hangfire, Quartz.NET, Serilog/NLog - Integration: JSON, XML, CSV, FTP/SFTP, OAuth2, JWT - DevOps: CI/CD automation, deployment pipelines - Optional: Middleware, API Gateway, Message Queues (MSMQ, RabbitMQ) Qualifications: - Bachelors degree in Computer Science, Engineering, or a related field. - Minimum 5 years of hands-on experience in software development and integration. - Proven expertise in designing and implementing scalable applications. - Strong analytical and problem-solving skills with a proactive approach. Nice to Have: - Experience with cloud services (Azure, AWS, GCP). - Knowledge of containerization tools like Docker or Kubernetes. - Familiarity with mobile deployment workflows and app store publishing.
