Turning data into decisions.

I'm a versatile engineer with 4+ years of experience spanning software testing, data operations, and ML at Tata Consultancy Services and AVM IT Solutions — from validating production systems to building end-to-end pipelines and ML models.

Currently completing my M.S. in Applied Data Intelligence at SJSU, I'm diving deep into ML systems, multimodal AI, and production-grade data engineering. I'm passionate about building systems that are not just technically sound — but genuinely useful.

I'm actively seeking full-time roles in Data Science, ML Engineering, Data Engineering, or Software/QA Engineering.

Experience

Building data systems that cut reporting cycles, improve accuracy, and drive business decisions.

Data Operations Analyst

Tata Consultancy Services · Bangalore, India

Dec 2022 – Jul 2024

  • Uncovered data drift between marketing spend and sales across millions of transaction records using Python, SQL, and Excel — directly prompting stakeholders to overhaul ROI reports and reallocate budgets.
  • Rebuilt data extraction and transformation pipelines end-to-end with rigorous cleaning, preprocessing, and EDA to deliver audit-ready business reports.
  • Engineered automated data quality monitoring workflows that cut the reporting cycle from 5 days to 2 days and pushed accuracy from ~86% to ~95%.
  • Designed and owned interactive dashboards in Power BI, Tableau, and Excel tracking CPA, channel ROI, and spend performance for cross-functional stakeholders.

Associate System Engineer (Software Testing)

Tata Consultancy Services · Bangalore, India

Nov 2021 – Dec 2022

  • Designed and executed 20–25 functional and data validation test scenarios per project across 6 projects, improving release quality and requirement traceability.
  • Developed and optimized SQL queries and backend data operations to support stable application workflows and reliable data availability for downstream systems.
  • Investigated and resolved 20+ critical production incidents using Remedy, collaborating with cross-functional teams to minimize downtime and improve system reliability.
  • Created and maintained technical documentation — test cases, SRS artifacts, and support artifacts — to improve audit readiness and cross-team knowledge transfer.

ML Intern

AVM IT Solutions · Bangalore, India

Jan 2020 – Jun 2020

  • Cleaned, preprocessed, and engineered features from 2,000+ biometric records using Python (NumPy, Pandas, OpenCV).
  • Built and compared Logistic Regression, Random Forest, and Neural Network classifiers — Random Forest outperformed the baseline by 6.33% and became the recommended model.
  • Visualized model performance and analytical findings using Matplotlib, Seaborn, and Tableau for both technical and business stakeholders.
