About this Gig
Corrupted data, broken JSON schemas, and formatting errors break production pipelines and distort business metrics.
I engineer resilient data cleaning systems that transform raw, messy data into clean, validated, analysis-ready assets.
What I Deliver:
- Syntax & Schema Validation: Fix corrupted JSON, XML, and CSV files for seamless API ingestion.
- Deep Data Cleansing: Remove duplicates, handle missing values, eliminate outliers, and enforce data types.
- Schema Normalization: Standardize relational schemas, date formats, and nested JSON structures.
- Automated Pipelines: Build reusable Python and SQL scripts for automated recurring cleaning tasks.
Why Work With Me:
Computer Engineer specialized in Big Data & Cloud Computing with 50+ deployed production pipelines. I ensure strict data integrity, privacy, and zero data loss.
Pricing & Scope Transparency:
Base packages cover single-file diagnostics, syntax fixes, and sample datasets. Multi-table enterprise databases and full ETL ingestion architectures are quoted via custom offers.
Message me with your sample data to get started.

FAQ
Why do full projects cost more than the entry packages?
Entry packages cover single-file fixes, syntax error resolution, and initial diagnostics. Full-scale database migrations, high-volume automated ETL pipelines, and multi-source API data wrangling require dedicated system scoping and are delivered via tailored custom offers.
How do you handle data privacy, confidentiality, and NDAs?
Your data security is paramount. I follow strict data governance practices: all client data is processed in isolated, encrypted local environments, never shared with third parties, and permanently deleted immediately upon order completion. Mutual NDAs are welcomed.
What final deliverables and post-delivery support do you provide?
You receive cleaned datasets in your required format (CSV, JSON, SQL, Parquet, or Excel) along with documented Python cleaning scripts or Jupyter Notebooks for complete reproducibility.
What information is needed from me to begin?
Please share a sample of your raw data, specify your required output format and schema rules, and list any edge cases you need handled. If you are unsure about the formatting details, simply send the raw file for an initial review.
