What I bring to a team.
Four areas I go deep in. Everything here is something I've shipped to production - not a line on a skills list.
Backend & APIs
Design and build the APIs and data models a product runs on - fast, correct, and still sane a year later.
What it looks like
- REST and WebSocket APIs with documented, versioned contracts
- Relational data modelling, query & ORM optimisation, caching
- Auth, roles & permissions (RBAC), rate limiting
- Background jobs, queues and scheduled pipelines
- Observability: structured logging, metrics and error tracking

AI & LLM systems
Take an AI idea out of the notebook and into production - grounded, guarded, and fast enough to sit in front of users.
What it looks like
- RAG and hybrid semantic + keyword search over your own data
- LLM automation for support, intake, triage & document workflows
- Agentic workflows with tool use and human-in-the-loop
- Guardrails, evaluation and latency / cost optimisation
- Streaming chat and smart-search UX wired into the product

Real-time & systems
Build the live, multi-tenant plumbing that has to stay correct under concurrency.
What it looks like
- Real-time updates over WebSockets (dashboards, chat, order flow)
- Audio / video calling with WebRTC
- Multi-tenant architecture with per-tenant isolation and RBAC
- Transactional correctness: billing, inventory, split payments
- Computer-vision pipelines over live camera streams

- AWS: EC2, Lambda, S3, RDS, API Gateway, CloudWatch
- Docker, Nginx, CI/CD and staging environments

Looking for someone who ships? Let’s talk.
I’m actively looking for a backend or AI engineering role. If your team needs an engineer who can own systems end to end, I’d love to hear about it.
