ADG Data Preparation & Open Sourced Enhancement collects, cleans, deduplicates and enriches data from multiple sources, documents it and packages it for ML and analytics teams.
You get reproducible datasets and faster model delivery.
🔸 Ready to use datasets for ML/BI. 🔸 Faster model delivery (data part already done). 🔸 Single source of truth instead of 5 ad hoc exports. 🔸 Ability to publish/open source part of data. 🔸 Documentation for onboarding new team members. 🔸 Repeatable data factory.
Do you have data scattered across 5 systems and Google Sheets? We pull and consolidate it.
Do reports differ because of duplicates and naming? We standardize entities and remove noise.
Do your models underperform because features are naive? We add task specific features
Do you lack context in your data (geo, company, asset)? We enrich it from open sources.
Do you need labeled data but don't want to do it manually? We set up semi automated labeling.
Do people ask 'which dataset did you train on'? We keep versions and lineage.
Do new team members struggle to understand the data? We deliver schema, samples and docs.
Do you want proof that better data gives better model? We run benchmarks and show uplift.
Enumerate DBs/APIs/files, define join keys and ID contracts so downstream joins stop breaking.
Ingest & stage
Build repeatable pulls with lineage and schema checks. Stage raw and cleaned layers for reproducibility.
Clean & normalize
Dedup, type fix, reconcile codes. Small, audited transforms that are easy to diff when something regresses.
Enrich & features
Add open data, compute features that lift models or BI. Keep feature logic as code with tests.
Pack & publish
Deliver Parquet/CSV plus schemas, sample queries and a quick start. No vendor lock-in, just files and contracts.
Validate & handoff
Business spot checks, data QA, and handover of refresh cadence and ownership.
Refresh (optional)
Scheduled deltas, quality gates, versioned releases so analysts and models don’t break when inputs change.
Documentation & Reporting (optional)
We produce lean, engineer-first artifacts that can scale to audit grade if needed - diagrams, IaC refs, runbooks, SLO dashboards, and change logs. Evidence packs are versioned and reproducible: links point to live systems or CI exports, not slides. Scope is tailored per client - from a 1-page ops sheet to a full compliance bundle with test replays and data lineage. If you prefer, we keep it minimal and focus on code and metrics only.
