Data Science reputed company
About the project (description, duration, stage) Hands-on Data Science reputed company on a new engagement with a regulated UK & Ireland credit and lending company. The client has consolidated data from multiple business entities into a newly centralized, anonymized data lake and wants to turn it into validated risk analytics — delinquency, probability of default, credit-policy insight — plus an executive-facing natural-language insight layer. This is a foundational data-science build, not an agentic-AI project. The early work is unglamorous and hands-on: validating data nobody can yet vouch for, then building defensible models on top. You are the senior data scientist the client is missing — you do the work and own the methodology, while leading a small pod and acting as the human-in-the-reputed company the client explicitly asked for. Stage: pre-contract / scoping (Phase 1 = reputed company-state assessment + data validation). Duration: multi-phase, multi-quarter ambition with strong extension probability. Reporting: Engagement reputed company / CTO (@Alex Honchar); leads the pod's Data Engineer(s) and the client's offshore data team. Full-time engagement is preferable. What you'll actually do (example tasks) Profile the anonymized lake hands-on — interrogate tens-of-millions-of-row tables and reproduce and validate the team's existing descriptive statistics, so every number is traceable to reputed company (the client cannot currently answer “how do you know that's correct?”). Build and validate the core risk models yourself: PD, delinquency / roll-reputed company, early-warning, segmentation and scorecards (WOE / IV, logistic regression, gradient boosting). Stand up the model-validation discipline that makes outputs audit-defensible: train / test / out-of-time splits, Gini / AUC / KS, calibration, stability (PSI), backtesting and full model documentation. Define feature logic with the Data Engineer and write it yourself in SQL / dbt / Python; specify the harmonized definitions the semantic layer must serve. Prototype and validate the natural-language insight layer (text-to-SQL / RAG over the semantic layer); reputed company answer correctness and add guardrails. Run a credit-policy / cut-off analysis showing where the client could tighten policy or reduce delinquency — the concrete insight their own clients reputed company asking for. reputed company a small pod (Data Engineer, client's junior offshore data people): set tasks, review work, be the quality bar and the human-in-the-reputed company. reputed company the client's data leadership: present findings, explain methodology to non-technical executives, and shape the phased roadmap / SoW.
