Vetted on a call by a Wave consultant, not scraped. Up to £85,000.
Azure Data Factory and Databricks for 6 years, building end-to-end ETL for construction industry data platforms, with PySpark, Delta Lake and medallion architecture from bronze through to gold. Dimensional modelling, star schemas and SCD Type 2 are routine rather than theoretical. Cut pipeline processing time by 70% on one platform. AWS Glue and S3 on the other side of the fence.
Looking forSix years with the same firm and the contract ends this month, so the timing is forced as much as chosen. Wants exposure to different enterprises, industries and technology stacks after a long run in one place.
How they came acrossComfortable writing production-grade code and the technical read was solid. Already moving through a process with a defence and intelligence business, so there is competition for them.

Only 2 employers in 13 years, an Indian infrastructure group and then 6 years at an IT services firm, the last few of those working remotely from the UK. Average tenure 3 years 8 months, longest 5 years 8 months.
The entire career sits with two employers and the recent work has been remote for an overseas firm, so UK-based team experience is untested. Contract ends this month.
Masters in Computer Applications.
Contracting at a UK government public health body, building AWS pipelines that process petabytes. Python, SQL and Spark with Glue, EMR, Lambda and Athena, plus Snowflake and Airflow. Two years before that on Azure Data Factory and Databricks at a large UK bank, so both major clouds are genuinely covered rather than listed. Batch and streaming both on file, with Kafka and Spark Streaming.
Looking forContracting now but wants a permanent role, and £75,000 upwards was the marker they gave. Keen to stay in large-scale cloud data processing rather than drift sideways into analytics.
How they came acrossReacted well to the role we talked through, and to the API side of it in particular. Thin on personal detail beyond that, so worth a proper conversation before forming a view.

Two employers in 6 years on file, a large UK bank and then a government public health body on a contract basis. Average tenure 2 years 4 months, longest 2 years 8 months.
Available immediately and currently contracting, so a competing contract offer is the main risk. £75,000 is a floor rather than a target.
Bachelors in Finance and Accounting.
Snowflake migrations with medallion architecture, Airflow and MWAA for orchestration, dbt and Python, and a real feel for prising hidden business logic out of legacy systems and turning it into a model. Third normal form, star schema and SCD Type 2 all used rather than just listed. The unusual extra is graph theory and network analysis with NetworkX, plus GIS work with GeoPandas and Shapely.
Looking forMoving deeper into data engineering on purpose, on the view that generalist software work is what AI eats first. Wants to pick up Kafka, event-driven architecture, real-time streaming and knowledge graphs, and would take less money for a role that teaches them.
How they came acrossCandid about the gaps, and flagged missing pieces on some briefs themselves rather than bluffing through. A decade in and still framing the next role around learning, which is rarer than it sounds.

Six employers over 18 years, taking in early sales roles, software development at an insurance software house, integrations at a fibre network business, data engineering at a consultancy and now an energy trading platform. Average tenure 3 years 2 months, longest 6 years 4 months.
Asking £54,000, which is well under the market rate for the experience, and has said they would trade salary for learning. Kafka and real-time streaming are ambitions rather than experience.
Masters in Philosophy.
