I am a Senior AI Data Engineer focused on turning LLM-powered ideas into production features. I design agentic workflows, retrieval-augmented generation, and scalable AI services on AWS, with a bias for reliability, observability, and safe, privacy-preserving practices. I enjoy collaborating with product and platform teams to iterate from rapid prototyping to production monitoring, build guardrails, feedback loops, and regression suites, and help teams scale AI features responsibly.…I am a Senior AI Data Engineer focused on turning LLM-powered ideas into production features.

Experiencia laboral

Senior AI Data Engineer at Choreograph (WPP)

August 1, 2024 - November 18, 2025

Led LLM features in production with an AWS-first (and GCP-hybrid) setup. Designed a LangGraph-based agent orchestrating tools for audience lookup, budget planning, and channel mix, persisting memory/state in PostgreSQL for multi-step sessions. Integrated the agent into the existing FastAPI backend with modular routers, DI, OIDC auth, and quota controls; documented via OpenAPI. Instrumented LangSmith for trace-level monitoring/evaluation and built dashboards for latency, tool errors, and drift signals across prompts and retrieval strategies. Shipped document intelligence & extraction via RAG (LangChain) over briefs and historical performance docs; curated prompt templates tuned to marketing use cases. Established feedback loops (annotation queues, error triage) and introduced prompt/version stores and regression suites. Partnered with platform/data teams to improve observability and scale on EKS/Lambda; IaC + CI/CD with Terraform/GitHub Actions.

Senior Data Engineer at Etsy (Depop)

July 1, 2024 - July 1, 2024

Orchestrated Spark pipelines on Kubernetes with Airflow to supply features/datasets for ML & analytics; improved text-data quality gates. Authored internal Python SDKs to standardise dataset access and feature computation; improved developer productivity and consistency. Integrated dbt models and data lineage (DataHub); documented contracts and exposures for downstream consumers. Automated infra with Terraform; added CI checks and deployment pipelines (GitHub Actions) to increase reliability.

Senior Data Engineer at BlueOrange

1 de enero de 2022 - 1 de enero de 2022

Introduced Kafka AVRO + Schema Registry patterns; standardised ingestion and schema evolution for downstream analytics. Built Snowflake and BigQuery models; implemented cost/perf practices (partitioning, clustering, task scheduling). Containerised Python services (Docker), established CI/CD, and delivered reliable data products for analytics teams.

Senior Software Engineer at BJSS

May 1, 2020 - May 1, 2020

Built secure APIs and automated CI/CD for government platforms; contributed to observability and performance tuning. Worked across teams to integrate services with reporting/analytics layers and testing frameworks.

Senior Backend/Data Engineer at Telecine

December 31, 2019 - December 31, 2019

Built high-throughput Flask microservices backed by DynamoDB/DocumentDB with retries and idempotency. Delivered event pipelines (Kinesis Firehose → S3 → Glue → Redshift) with cataloguing and partitioning for downstream analytics.
