Elie Ben-Shlomo
Freelance Software Engineer
Engineering lead with 8+ years building enterprise software across startups and megacorps across Bristol, London, and San Francisco. I like to solve problems at the intersections of mathematics and technology, with a particular interest in the research and development side of software engineering.
Extensive history of building data intensive, event driven, scalable systems. Experience spans realtime cloud infrastructure, machine learning platforms, and quantum computing R&D, working across both greenfield and enterprise environments.
Reach out to me for consultations on one off software jobs, long term contracts, business ventures, and perm opportunities. If you have a difficult problem you need solving, I want to hear about it!

Relay
Staff ML Engineer
Jul 2025 – Oct 2025- Building ML pipelines to train, evaluate, and deploy models, hosting productionised models. Automatic handling of model versioning, error catching, and type safety. Realtime model monitoring (eval metrics, data/feature drift) with dashboards and alerting.
- Working directly with stakeholders across DS, Eng, and Product to architect project timeline, from model design, EDA, implementation, and productisation, managing project value and lift.
- Reviewed and integrated third-party feature-store (ChalkAI) into ML platform for rapid feature retrieval.
Sky
ML Engineer
Apr 2023 – Jun 2025- Empowering Data Science at scale: designed and built Sky's Feature Store — a centralized repository of user-defined features ingested into ML models across the company — ensuring efficient, low-latency feature engineering & retrieval for personalised user experiences. Operating at massive scale under the 2024 Paris Olympics and US Super Bowl (30M concurrent users).
- Realtime ML Systems Engineering + Serving: ingesting terabytes of data from hundreds of pubsub topics into a scalable k8s cluster [p99 < 500ms]. Designing a high-throughput, low-latency online store enabling efficient feature access and maximizing prediction accuracy [p99 < 25ms].
- Scaling ML Systems: orchestrating and maintaining scalable GCP microservices using BigQuery, BigTable, Dataflow, and VertexAI.
- Cloud Infrastructure: architecting resilient GCP microservices for massive-volume data ingestion. Built graphing and alerting via Prometheus, Grafana, and Sky's internal callout system.
