ABOUT SONU WILSON
Software Engineer with 9 years of experience designing and building scalable backend systems, RESTful APIs, and data pipelines using.NET technologies (C#.NET Core/6/7/8). Based in Reading, UK, with proven expertise in highly regulated industries: railway transport (Siemens), defence, and education. CORE EXPERTISE* API & Microservices: Designing RESTful APIs, microservices, and secure authentication (OAuth2, JWT, Identity Server).* Data Engineering: ETL/ELT pipelines, batch processing, and high-volume data ingestion daily records).* Cloud & DevOps: Azure (DevOps, Functions, Service Bus) and AWS (Lambda, EC2, S3), Docker, and CI/CD.* Databases: MS SQL Server (T-SQL, query optimization); NoSQL concepts.* Architecture: Microservices, event-driven, distributed architectures, asynchronous messaging (RabbitMQ, Azure Service Bus). KEY ACHIEVEMENTS* Developed ETL services processing student assessments daily with 99.5% system reliability.* Built low-latency microservices for telemetry data (sub-100ms response times).* Optimized SQL queries, achieving 35-50% performance improvements.* Implemented CI/CD pipelines with Docker, reducing deployment time by 70%.* Consistently maintained 85%+ unit test coverage (XUnit/NUnit).🤝 APPROACH & FOCUSI thrive in Agile, cross-functional teams (Data Engineers, Architects, QA). I am analytical, detail-oriented, and focused on writing clean, maintainable code. I enjoy solving complex technical challenges and driving project success in security and compliance-focused environments. OPEN TOContract/Permanent roles in the UK focusing on challenging backend systems, API development, data engineering, and microservices architecture, particularly in fintech or regulated industries.
