What I can do for you

Focused engagements with clear deliverables. I work as an independent contractor — no agency overhead, direct communication, and accountability for every line shipped.

🔗

API & Microservices Development

Production-ready backends, built to scale

I design and implement RESTful and event-driven APIs using Java / Spring Boot, with a focus on clean architecture and long-term maintainability. Whether it's a greenfield service or integrating with third-party providers, I'll deliver something your team can build on.

Typical deliverables

  • ✓Spring Boot / Spring Cloud microservices
  • ✓REST API design, documentation, and testing
  • ✓Third-party integrations and e-roaming / OCPP protocols
  • ✓Message queuing (Kafka, RabbitMQ)
  • ✓Service-to-service communication patterns

Best for: Startups and scale-ups building or expanding their backend platform

☁️

Cloud Infrastructure & DevOps

Reliable infra, automated pipelines

I provision, configure, and optimise cloud infrastructure across AWS, GCP, and Azure. From containerised workloads on Kubernetes to CI/CD pipelines and monitoring, I'll make sure your deployments are repeatable and your systems observable.

Typical deliverables

  • ✓Kubernetes cluster setup and service deployment
  • ✓Docker containerisation and image optimisation
  • ✓CI/CD pipelines (GitLab CI, Jenkins, GitHub Actions)
  • ✓Infrastructure-as-code (Terraform, CloudFormation)
  • ✓Monitoring and alerting setup

Best for: Teams moving from manual deployments to automated, cloud-native delivery

System Design & Architecture

Technical clarity before you write a line of code

Good architecture pays back every sprint. I work with product and engineering teams to map out system boundaries, data flows, and scalability constraints — producing designs that avoid common traps and give engineers a clear roadmap.

Typical deliverables

  • ✓Architecture review and documentation
  • ✓Microservices decomposition strategy
  • ✓Database schema and data modelling
  • ✓Scalability and reliability planning
  • ✓Technology selection and trade-off analysis

Best for: CTOs and tech leads planning new systems or modernising legacy platforms

Healthcare & Biotech Software

Domain knowledge meets engineering rigour

I've built clinical software, spatial gene expression tools, and data processing pipelines for research workflows. I understand the domain requirements — data integrity, audit trails, and performance under analytical workloads.

Typical deliverables

  • ✓REST APIs for clinical and research applications
  • ✓Image and statistical data processing pipelines
  • ✓Desktop tool backends (.NET Core / Java)
  • ✓Data visualisation APIs
  • ✓Compliance-aware system design

Best for: Biotech and healthtech companies needing an engineer who knows the domain

⚡

E-Mobility & IoT Platforms

Embedded protocols and cloud scale

Hands-on experience building and optimising EV charging platforms, including OCPP-based backend integrations, e-roaming provider connectivity, and Kubernetes-hosted microservices for high-concurrency charging events.

Typical deliverables

  • ✓OCPP / e-roaming backend integrations
  • ✓Charging session management services
  • ✓Real-time event processing
  • ✓Scalability improvements for concurrent connections
  • ✓Architectural best practices for IoT platforms

Best for: E-mobility startups needing specialist backend expertise

🧹

Legacy Modernisation

Migrate without breaking what works

Moving from a monolith, upgrading a stack, or migrating to the cloud? I've done it in regulated and high-uptime environments. I'll define a phased migration plan that reduces risk and keeps your team shipping throughout.

Typical deliverables

  • ✓Monolith-to-microservices migration planning
  • ✓Cloud migration strategy (lift-and-shift or re-architect)
  • ✓Incremental refactoring with test coverage
  • ✓Dependency modernisation
  • ✓Knowledge transfer and documentation

Best for: Engineering teams inheriting or outgrowing an aging codebase
