Technical leadership for AI workflows, scalable platforms, cloud architecture, and developer tooling

Jerome Thayananthajothy

Technical Lead | AI-Driven Systems Architect | AWS & Full-Stack Expert | Open Source Contributor

Open to selected global technical-leadership conversations.

I’m a Technical Lead and Generative AI Engineer focused on building intelligent, high-scale systems that merge traditional full-stack engineering with next-generation AI capabilities. Over the past decade, I’ve led architecture modernization initiatives across e-commerce, analytics, and workflow automation driving multimillion-pound cost reductions, boosting performance, and introducing AI-augmented features like semantic search and agentic workflows. I’m particularly interested in AI-enhanced infrastructure, multi-cloud orchestration (AWS, Azure, GCP), and scalable developer ecosystems. My engineering philosophy is rooted in system design, observability, and enabling teams to ship fast with confidence.

AI, architecture, full stack, and delivery

What I can lead

Senior engineering work where architecture, product judgment, and team standards meet.

The site is positioned for focused conversations around work where technical leadership has to create leverage, not only write code.

AI platforms

Designing observable AI workflow systems, evaluation paths, and production guardrails that teams can operate with confidence.

Architecture modernization

Moving legacy platforms toward typed services, clearer boundaries, and resilient delivery without pausing commercial momentum.

Engineering standards

Raising code quality, release hygiene, observability, and review practices so teams ship faster with fewer hidden costs.

Product delivery

Connecting technical choices to user value, roadmap trade-offs, and maintainable product execution.

Selected Work

Open-source tools with real adoption, plus product work with commercial intent.

The portfolio leads with projects that have earned usage and trust. Each card keeps the story practical: what it is, why it exists, and the engineering choices behind it.

Filterable

19510

Enhance Laravel queries with adaptable, customisable filters and intelligent caching to improve both performance and functionality.

  • Filterable is a Laravel package for turning HTTP request parameters into rich, composable Eloquent query filters. The base Filter class exposes a stateful pipeline that you can extend, toggle, and compose with traits to add validation, caching, logging, rate limiting, memory management, and more. Everything is opt-in, so you enable only the behaviour you need while keeping type-safe, testable filters.
