Aggregate data scattered across :

- Databases

- Strong knowledge of relational databases (PostgreSQL, MySQL, etc.)

- Experience building ETL / data pipelines

- Exposure to unstructured and semi-structured data

- Experience handling PII / PHI anonymization

- Ability to interact confidently with clients and understand real-world data problems

Good to Have :

- Experience with AWS / GCP / Azure

- Exposure to data migration or data warehousing projects

- Automation or scripting for data processing

- Who Should NOT Apply (Important)

- Pure Java backend / application developers without data engineering exposure

- Candidates with less than 5 years of experience

- Candidates looking only for API, microservices, or application development roles

Why Join Apptware ?
