On building product platforms that don't apologise for scale. Frontend craft and backend depth, rendering strategy, event-driven services, and cloud-native infrastructure — from the first paint down to the data layer. End-to-end, by design.

instinct.

Equally comfortable shaping frontend platforms in React, TypeScript, Redux, component architecture, and rendering strategy, and backend systems with CQRS, circuit breakers, event-driven services, and cloud-native AWS infrastructure. Leads globally distributed teams, mentors staff-level decisions, and ships with measurable outcomes.

Recently integrating GenAI systems (Azure OpenAI, AWS Bedrock) into enterprise workflows, focused on reliability, security, and explainability.

  1. AWS Lambda Web Functions vs Event Functions vs EC2/ECS

    AWS Lambda now has three types of function. Here's how the new Web Functions differ from classic Event Functions, where they beat EC2 and ECS (scale to zero, no clusters, one-command multi-region), and where ECS is still the better choice (Java, WebSockets, steady high traffic).
