Baxter Healthcare is a Fortune 500 American healthcare company with a presence in the UK. It's a leading supplier to the NHS.
Led my team from SAG (Soluciones Almonte Gil) in the Dominican Republic to augment Baxter's development team in Bengaluru, providing technical leadership for modernising their legacy application estate.
Working with the development team, we retrofitted modern software engineering tools, practices and standards to those legacy applications. We introduced CI/CD pipelines for SQL Server databases, WinForms applications, TopShelf windows services and web applications using Team Foundation Server (TFS/Azure DevOps Server). The result was that the team transformed 2+ hour error-prone processes to an automated workflow able to deploy code in under 5 minutes from a pull request.
The team also developed internationalisation (I18N, multi-language support) support for the legacy windows application, featuring metaprogramming with Roslyn for extraction and transformation, Angular 5 front end backed by asp.net web API for translation maintenance.
A PROJECT I'M REALLY PROUD OF:
Designed and delivered a mission-critical pharmaceutical order processing system now in production across Australia, New Zealand and the UK. The platform processes HL7 healthcare messages and manages compounding orders with precise drug concentration calculations where accuracy is essential for patient safety.
The solution features a distributed actor-based architecture using Akka.NET for fault-tolerant, concurrent message processing with automatic failure recovery. Built the full stack: Angular admin interface, ASP.NET Core APIs, actor-based processing engine, and AWS Lambda microservices for external pharmacy integration.
Established multi-region CI/CD pipelines with Terraform-provisioned infrastructure, enabling automated deployments across APAC, EMEA and North American environments.
