PROJECT 1
January 1, 2018 – June 1, 2026
Configured and maintained source-to-target system connections within Talend metadata, ensuring secure, reliable, and accurate data access across environments. Performed data cleansing, enrichment, transformation, and uniqueness checks to maintain high standards of data quality before loading into target systems. Designed and implemented complex data flows using Talend components such as tFilter, tSortRow, tUnite, tReplicate, tSample, tAggregate, tMap, and tJoin, parlance for optimizing performance and scalability. Developed and implemented Slowly Changing Dimension (SCD) Type 2 logic using tMap and expression builder to manage historical tracking and versioning in dimensional data. Ensured error handling and exception management using components like tLogRow, tLogCatcher, tFlowTolterate, tDie, and tJavaFlex, improving job reliability and traceability. Extracted the raw data & maintain the uniqueness using the tunite along with tunique row & maintain the non reputed record used the TAC for the deployment & scheduling purpose along with github &Jenkins. Collaborated effectively in Agile/Scrum teams, participating in daily stand-ups, sprint planning sessions, and walkthrough meetings while updating and tracking tasks using JIRA.
PROJECT 2
January 1, 2018 – June 1, 2026
Extracted data from diverse source systems using Talend components like tDBInput and tFileInputDelimited, ensuring efficient retrieval from databases and flat files. Filtered and sampled data with components such as tFilterRow and tSampleRow to isolate relevant subsets and reduce data processing overhead. Utilized tMap for complex data transformations, including removing duplicates, handling null values, and applying conditional logic to meet business rules. Integrated advanced SQL queries within Talend jobs to perform transformations beyond the capabilities of standard components, enhancing flexibility and efficiency. Implemented comprehensive error detection and logging mechanisms using tLogRow, tLogCatcher, and tDie to capture runtime issues and ensure smooth job execution. Loaded cleansed and transformed data into target systems using components like tDBOutput and tFileOutputDelimited, supporting both structured database targets and flat file outputs.
Cultural Fit Analysis
The candidate's experience in Agile/Scrum teams, participation in daily stand-ups, and use of JIRA suggest a good cultural fit for collaborative and iterative development environments. The projects described are professional and align with typical enterprise data integration needs. However, the candidate's experience is heavily specialized in backend ETL development, which is a significant mismatch for a 'Frontend Developer' target role. This specialization limits the breadth of skills relevant to a frontend position, impacting cultural fit for a team focused on user interfaces and client-side technologies.
Soft Skills & Operational Fit
The candidate demonstrates strong operational fit within an ETL development team, particularly in Agile/Scrum environments. Their experience highlights a focus on data quality, error handling, and collaborative project execution. The resume indicates a commitment to continuous learning, which is a positive soft skill for adapting to evolving data technologies.
