I am a Software Engineer and Data Engineer with 2+ years of experience building reliable backend services, optimizing SQL performance, and automating data workflows. I’ve led a zero-downtime SQL Server migration across 12 production instances and 85 databases, and I cut p95 query latency by ~40% through plan guides, indexing improvements, and careful tuning. I also built dashboards to surface failures and regressions, helping stakeholders review weekly trends. I’m obsessed with measurable outcomes, reliability, and clean runbooks. I enjoy turning complex problems into repeatable processes, reducing toil with automation, and collaborating with teams to drive continuous improvement.…I am a Software Engineer and Data Engineer with 2+ years of experience building reliable backend services, optimizing SQL performance, and automating data workflows.

Work Experience

Software Engineer at Tata Consultancy Services (TCS)

October 1, 2021 - December 1, 2022

Automated recurring SQL Server administration tasks (backups, index maintenance, job health) with PowerShell, reducing weekly manual ops by ~30% and saving 120+ engineer-hours per year; led a zero-downtime production migration from SQL Server 2016 to 2019 across 12 instances and 85 databases by staging replicas, rehearsing cutover runbooks, and validating with synthetic checks; implemented Always On Availability Groups and optimized top slow queries (plan guides, covering indexes, and parameter sniffing fixes) to reduce p95 latency from 420ms to 250ms; built Tableau and Grafana views to monitor job failures and query regressions, enabling weekly trend reviews with stakeholders.

Software Engineer at Wipro

May 1, 2021 - September 1, 2021

Rewrote row-by-row stored procedure logic into set-based operations for pharmacy datasets, lowering ETL time from ~27 min to ~8 min and improving reliability; built a PowerShell backup-check utility and wired it into CI/CD, adding pre-deploy guardrails that yielded zero missed backups across three environments in Q3 2021; performed schema conversion and established PostgreSQL test environments, standardizing dev data refresh scripts to keep feature branches reproducible; shipped weekly health dashboards (jobs, storage, waits) that surfaced top bottlenecks and informed the tuning backlog.
