A LITTLE ABOUT ME

And why I am your new secret weapon

Senior full-stack engineer with 15+ years building high-impact, business-critical products — from award-winning digital experiences to real-time platforms in fintech and sports betting. I’m strongest where UX, performance, and systems design meet: fast UIs, complex data, and zero-drama delivery.

Today I’m focused on GenAI and agentic systems that are built to run in production: grounded with RAG, measurable with evals, observable in runtime, and controlled with clear boundaries and human-in-the-loop workflows. I treat “AI features” as software engineering: reliability, maintainability, and predictable cost.

Open to Senior / Staff roles where full-stack delivery, GenAI adoption, and technical leadership overlap — mentoring teams, raising quality bars, and shipping systems that stay correct over time.

MY STRENGTHS

"attention to detail" - really you want to read that again?

  • High-stakes delivery: calm under pressure, strong ownership, and predictable outcomes.
  • Product + engineering mindset: turn fuzzy goals into clear milestones, trade-offs, and shipped value.
  • Real-time & performance: proven with high-frequency data, caching, profiling, and browser optimisation.
  • GenAI done properly: RAG grounding, evaluation, observability, guardrails, and cost/token discipline.
  • Pragmatic architecture: clean boundaries (microservices / modular front ends), testability, and maintainability.
  • Team amplifier: mentoring, code reviews, hiring support, and clear technical communication.
  • Creative technologist: bridge design and engineering to ship experiences users actually love.
  • Easy to work with: direct, collaborative, and happy to make others look good.

MY SKILLS

Modern full-stack + production GenAI (no buzzword soup)

Front end: React, TypeScript, Next.js, Redux, Tailwind/SASS, accessibility, performance profiling.

Back end: Node.js, REST/GraphQL, microservices, SQL/NoSQL, background jobs, integrations.

Cloud & DevOps: Docker, CI/CD, IaC concepts, serverless, observability, incident-friendly deployments (AWS/Azure/GCP).

Quality: Jest, Cypress, TDD where it pays, pragmatic automated testing, code review culture.

GenAI / LLM systems: RAG, embeddings/vector search, agent/tool orchestration, long-term memory patterns, evaluation & regression tests, tracing/monitoring, guardrails, and human-in-the-loop controls.

    Node.js • GraphQL • Microservices

    PostgreSQL/MySQL • MongoDB

    Docker • CI/CD • Cloud (AWS/Azure/GCP)

    Testing: Jest • Cypress

    Observability: logging • metrics • tracing

    GenAI: RAG • embeddings • evaluation • guardrails • HITL
