What I'm looking for

I seek senior engineering roles building secure, cloud-native, data-driven platforms in regulated environments, with cross-functional collaboration and growth.

I am a senior full-stack developer with 6+ years delivering secure, scalable, data-intensive web applications for regulated and enterprise sectors. I specialize in full-stack engineering, cloud-native deployments, backend optimisation, robust testing, and integrating AI/LLM APIs to enable advanced analytics and automated reporting.

My work has reduced production incidents, improved performance and coverage, and enabled regulatory compliance across multi-tenant environments. I collaborate closely with security, UX, and product teams to deliver user-centric, high-availability platforms that meet NIST CSF, ISO 27001, SOC 2, GDPR and NIS2 requirements.
