01
Application security
Review applications and source code, test agreed attack surfaces, and help teams understand what to address first. Findings are explained with evidence, context and practical remediation options.
- Application and code reviews
- Scoped penetration testing
- Security advice and remediation planning
A scoped technical review is not a certification or blanket compliance sign-off.
02
Architecture and application development
Shape a new system, modernise an existing application, or deliver a focused feature. Work can span architecture, implementation and integration, using technologies that fit the problem.
- C#, .NET, ASP.NET and web applications
- APIs, authentication, payment and third-party integrations
- Umbraco CMS, including Forms, Vendr, uSync and custom extensions
03
Performance and data-intensive systems
Investigate application and database bottlenecks, make the causes understandable, and prioritise changes. Experience includes SQL Server and T-SQL performance work and systems handling sensitive health and financial data.
- Application and database performance analysis
- Query and data-access improvement
- Practical plans for legacy or non-scalable systems
04
AI and automation
Identify useful, bounded applications for AI and automation, advise on policy and risk, and help integrate tools into software delivery and existing workflows.
- Responsible AI adoption and policy advice
- Development and workflow automation
- Agentic AI in software engineering
05
Technical leadership and delivery
Bring experienced technical direction to a team or project: clarify requirements, guide architecture, strengthen engineering practice, and help resolve difficult delivery or quality issues.
- Architecture and engineering standards
- Technical reviews, mentoring and capability uplift
- Scoping, estimates and delivery planning
06
Game development and products
Explore a game concept, prototype gameplay, or contribute to an existing project. HCS also builds and operates its own software products, applying the same practical engineering discipline.
- Game concepts and prototypes
- Gameplay systems and development tools
- Product engineering and ongoing improvement
