## About

I work with organisations on distributed data platforms, developer platforms, and application design—including how AI sits on top of that stack.

I started as a software engineer, then spent several years in solutions and sales engineering at Comcast (EMEA and APAC), where I was the technical lead on large media deals. I still like translating between engineers, product teams, and stakeholders—through architecture and workshops, but also by shipping production code and tuning systems when that is what moves the work forward.

## Skills

- **Architecture:** distributed data platforms, microservices and event-driven systems, cloud-native and API-first application design
- **AI:** LLM application architecture, RAG, vector search, orchestration (including LangGraph)
- **Engineering:** Python, Node.js / TypeScript, Java and Kotlin; REST and GraphQL; Kubernetes; AWS, GCP, Azure; MongoDB
- **Delivery:** technical sales, workshops and proofs-of-concept, developer enablement, production development

## Work

- [Bluteksbot](https://github.com/ricard0javier/bluteksbot): A production Telegram assistant—planning, tools, and memory—run as a single Compose stack for well under a dollar a day.
- [SA Systems](https://github.com/ricard0javier/sa-systems): A pre-sales command center for accounts, MEDDPICC, and relationship graphs, with an MCP server so agents can work the same model.
- [PostgreSQL to MongoDB sync](https://github.com/ricard0javier/postgres-to-mongodb-sync): A CDC reference that folds many SQL tables into one MongoDB document so a cutover can run for months with both stores in sync.
- [MongoDB Knowledge Base](https://github.com/ricard0javier/mongodb-knowledge-base): A mobile-first chatbot for SA knowledge: hybrid search, Voyage embeddings, and conversation state stored in MongoDB—no Redis sidecar.
- [Healthcare ontologies](https://github.com/ricard0javier/mongodb-ontologies): A demo of ICD-10, SNOMED, and RxNorm in MongoDB—search, hierarchy walk, and cross-code-system mapping.
- [AI Agent Framework](https://github.com/ricard0javier/template-async-agent-service): An event-sourced reply agent: MongoDB as store and RAG over prior messages, Redpanda as the inbox.
- [Health and Beauty Lab](https://healthandbeautylab.co.uk): IT setup and ongoing support for a UK health and beauty business—site, email, and the boring infrastructure behind it.
