ATLASSIAN | Senior Software Engineer, Backend
Reliability Engineering
- Created a Jira-wide Template for config-based generation of dashboards and alarms adopted by 25+ teams within the Jira Org with further adoption in progress.
- Introduced the concept of multi-trials and Volume based alerting that takes into consideration weekends and public holidays to prevent alarm noise.
Jira Attachments API
- Architected the backend API for filtering attachments based on types to introduce tabbed-layouts. Improved Attachment search times by 12%.
- Designed and implemented the backend API for consolidating static files and first party documents into a single API with support for multiple forms of pagination, sorting, and filtering.

MEDIA.NET | Manager - Web Tech
PurePlay - Video Content and Ad Serving
- Designed and Developed an ecosystem of services for video content curation using IAB and Sprig categories. Engineered storage and transcoding solutions for different bitrates and streaming formats.
- Integrated a customized Prebid solution for video ads to increase ad fill rates. Introduced a player solution that increased user-engagement by 18%.
- Within 4 months, the product contributed to a 2% increase in monthly revenue of the company.
Graph-Engine (Ad & Content Selection)
- Engineered a finite automata system for efficient Ad and Content selection on SERP. Managed API dependencies and compliances using Directed Acyclic Graphs (DAGs) to align with business requirements and increasing ad fill rate by 14%.
- Achieved a 40% reduction in server response times and 9% boost in revenue.
Re-Architecture Ad-Serving
- Led a team of developers in an architectural overhaul, replacing the traditional CDN caching layer with a scalable backend distributed system across data centers and cloud with improved cache hit rates. Reduced latency by approximately 200ms (35% of total response time).
- Boosted QPS per server by 40%, thereby reducing costs by 15% and boosted revenue by 3%.
IP to Geo Lookup Database
- Collaborated and launched a common multi-DC solution across teams by optimizing storage and lookups of IPv4 and IPv6 addresses using Quad Trees, Segment Trees, and sorted sets.
- Reduced lookup times by nearly 45% across all traffic.
