Senior Software Engineer · Aspiring Staff Engineer

Senior Software Engineer with 5+ years building backend systems, platform infrastructure, and developer tooling in Python. I specialize in designing resilient architectures, driving cloud and platform optimizations, and creating reusable frameworks that accelerate engineering teams. I’ve led technical initiatives end-to-end — from system design through delivery — and mentored engineers to raise code quality standards across organizations. Currently building at 6sense Insights on the AI Email team.

Experience

6sense Insights, Inc.

Nov 2025 – Present

Senior Software Engineer · AI Email Team

  • Developed automated data deletion workflows to support GDPR and CCPA compliance within an AI-driven email product, ensuring regulatory adherence at scale.
  • Migrated internal Spark-based data pipelines from a legacy platform to modern data infrastructure — zero downtime, zero production issues.
  • Leading the modernization of a CRM integration layer by transitioning from a team-maintained implementation to a centralized, company-wide compliant integration — reducing duplicated engineering effort and enabling retirement of self-maintained components.

Portcast Pte. Ltd.

Mar 2022 – Oct 2025

Senior Software Engineer · Remote

Technical Architecture & Systems Development

  • Led the design and development of the Control Dashboard for organization-level container management, delivering the MVP in under a month — a broader, generalized evolution of the earlier Risk Dashboard.
  • Led the design and development of the Risk Dashboard for real-time risk analytics, delivering the MVP within 1.5 months.
  • Architected and led development of the company’s first microservice for container data ingestion, processing 20,000+ containers/day. Created a foundational blueprint that reduced time-to-market for subsequent services from 1 month to 1 week.
  • Designed a DAG-based status code framework for complex state transitions, eliminating all client-reported data inconsistency issues. Implemented a time-travel feature for retrospective reconciliation.
  • Rewrote container refresh logic to centralize business rules and provide operational visibility, reducing recurring refresh issues to near-zero.
  • Integrated four external data pipelines for vessel metadata, container events, and terminal data, improving overall data completeness.
  • Built a dynamic org refresh system using a min-heap-based approach to distribute load evenly across the day.
  • Became the team’s go-to engineer for complex cross-system troubleshooting.
  • Led cloud optimization by migrating 15+ production DB instances to AWS Graviton and gp3 storage, reducing database operating costs by 20%.

Frameworks & Engineering Standards

  • Established the company’s internal PyPI repository and built four reusable packages used across microservices: Data Provider Fallback Manager, DB Router, API Usage Manager, and Portcast Utils.
  • Implemented trie-based logic in the Fallback Manager for efficient config-driven source selection and failover.
  • Codified company-wide code quality standards and CI/CD quality checks, measurably improving code consistency and reliability.

JPMorgan Chase & Co.

Aug 2020 – Mar 2022

Software Engineer (SEP II) · Bengaluru

Platform Development

  • Led the team’s migration to the firm’s strategic internal development platform, accelerating adoption through technical demos, knowledge-sharing sessions, and boilerplate APIs.
  • Collaborated with product owners across multiple services and owned 4 of the team’s 5 components.

Self-Service Tooling & Automation

  • Built self-service APIs that eliminated 200+ manual SRE tasks per quarter, saving 8–10 days of SRE effort.
  • Designed and built a concurrent job management framework, transforming a legacy single-user application into a multi-tenant platform supporting parallel requests.

Additional Contributions

  • Built a DAG-forest-based tool to upgrade transitive npm dependencies for rapid resolution of OSS compliance flags.
  • Volunteered in JPMorgan’s Force For Good program and created the Indian Heritage Walks website for Sahapedia.
