Led end-to-end AI-driven engineering initiatives and large-scale platform integrations, delivered cost optimisation efforts saving $15K+ annually, and built Java and C# SDKs from scratch spanning mobile and cross-browser testing.

Strong track record of cross-team ownership, mentoring, and delivering high-impact features from design through GA launch.

Senior Software Engineer (Promoted) at BrowserStack (2023-01 – Present)

• Drove multiple cost optimisation initiatives — including Datadog deprecation, logging pipeline cleanup, and infrastructure resource rightsizing — saving $15K+ annually.
• Led AI-driven engineering initiatives building internal AI-assisted tooling for automated deployments, cost tracking, and core metrics analysis — improving team efficiency and reducing manual operational overhead.
• Architected a large-scale platform integration end-to-end: authored technical specs, led cross-team syncs, built data migration scripts handling complex edge cases across multiple databases, and planned stepwise release.
• Delivered multiple deal blockers, including A/B testing, snapshot retry, and ignore regions to GA — resolved complex edge cases around compatibility and optimised code for production load.
• Implemented a role-based access control (RBAC) system: designed a granular permissions model across org, user, project, and token scopes with full backward compatibility.
• Integrated the platform with a third-party enterprise testing tool (Tricentis Tosca): added configurable snapshot options and validated parallel execution and mobile-specific behaviour. Led full ownership from the POC phase to GA.
• Mentored and onboarded 3 new engineers, conducted knowledge transfer sessions, and actively contributed to sprint planning and team process improvements.

Software Engineer at BrowserStack (2021-01 – 2023-12)

• Contributed to the development of 2 new products under visual testing — App Percy and Visual Scanner — spanning backend services, snapshot pipelines, and new data models; collaborated cross-functionally with product and QA teams for alpha and beta releases.
• Owned end-to-end delivery of Chrome on Android and iOS Safari browser support — from infrastructure provisioning and stabilisation to GA launch, including evaluating competing screenshot approaches and E2E testing.
• Built and owned Java and C# SDKs from scratch — designed architecture, tested across all supported devices, ran POCs for native mobile testing (XCUI/Espresso), and managed the full release lifecycle.
• Built a centralised observability layer on Looker: dashboards covering platform performance, API health (5xx error rate, Apdex), and automated cost tracking — replacing manual data collection across 5+ tools.
• Delivered authentication support (Basic/Form Auth) across the full stack and third-party webhook integration (MS Teams) with complete QA.
• Led migration of a critical request-handling worker from Cloudflare to GCP, ensuring backward compatibility and cost tracking.

Android Developer Intern at PanoSlice (2020-05 – 2020-06)

• Developed and shipped new features on a live Android application — including UI redesign, image masking, sticker support, and image containers — with end-to-end testing.

Bachelor of Engineering in Computer Engineering – Army Institute of Technology, Pune (2017-01 – 2021-01)
