  • Building a middleware layer for Solana token trading, transforming raw blockchain and exchange data into normalized, feature-rich feeds with integrated execution hooks for real-time trading.
  • Engineering a scalable data pipeline leveraging Helius gRPC Laserstream for high-throughput swap updates and Apache Kafka for distributed stream processing, enabling real-time monitoring and feature engineering across thousands of tokens.
  • Developing advanced trading features such as burst-buy detection, order-flow imbalance, rug-pull risk, and PVP activity tracking, supporting alpha generation through structured datasets.
  • Implementing execution modules (smart order routing, DEX swaps, and CEX routing) for ultra-low-latency trade execution driven by streaming signals.
  • Containerized and automated workflows with Docker, ensuring reproducibility, scalability, and deployment flexibility across environments.
  • Designing lightweight, fully automated trade management systems to optimize trade lifecycle handling with minimal human intervention.
  • Designing UI for health metrics dashboard as well as a trade-log including P&L records for monitoring, review and reporting purposes.

Senior Software Engineer

Meta, Inc. (Instagram/Threads)
04.2022 - 09.2025
  • Initiated, developed, tested, ran data analysis for and launched a user interface change in the header of Instagram feed posts, where multiple attributions (i.e. location, audio, etc.) cycle on one line as opposed to stacking vertically. This change led to an increase in 0.21% of post impressions and 0.25% increase in top-line revenue on Instagram.
  • Developed and launched IG Feed → Threads crossposting, leading to an increase of +510K daily original posts, +11% top-line original posts, and +185K eWAU on Threads.
  • Leading product development, engineering execution, and data analysis for new Threads onboarding from Threads shown in IG Feed; initial tests showing +40% onboarded users (+320K per day) and +50K new daily active users on Threads.
  • Developed and launched navigation change where tapping on a Thread in IG Feed directs to the tapped post being pinned to the top of main feed vs. a permalink view of the posts of replies. This change led to +2.12% eDAU, +1.34% eWAU, +1.74% post impressions on Threads.
  • Developed new aspect ratio view and cropping tool for the profile grid (1:1 → 3:4) to align with IG shift to Reels - leading to increase Reels consumption and engagement on profile (+0.45% imgs, +0.6% reshares, +0.24% likes, +0.67% saves).
  • Re-architected how attributions are displayed for an IG feed post into an attribution kit system completely in Swift (formerly Obj-C), refactoring each attribution to be protocolized, decreasing bugs in the header, easing code complexity, increasing attribution scalability, and increasing developer efficiency.
  • Re-developed the megaphone component (40 permutations) used in IG Feed for iOS (in Swift) and cross-platform (in php/Hack) to adopt new design principles.
  • Led, executed, and launched workstream to add attributions to original author for images reposted on IG to meet new legal requirements. Worked with the internal Rights Management team server engineers on implementation and execution.
  • Audited, owned, tested, and launched several different landing experiences for Threads integrations throughout Instagram, leading to increasing onboarded users and eWAU.
  • Led project aimed at aligning with the Digital Systems Act guidelines, collaborating closely with cross-functional teams, including product and relevance teams, to outline product requirements and designs, executing the development on iOS, overseeing various testing phases, and orchestrating a coordinated launch with other surfaces, all while adhering to a challenging time frame.
  • Developed video playback controls for Reels within the primary Instagram Feed, expecting to increase video engagement and consumption within the Feed.
  • Contributed to the Profile team's efforts by actively participating in the development and successful launch of multiple links in user bios.
  • Spearheaded efforts aimed at elevating end-to-end test coverage from 10% to a comprehensive 100% for core Explore flows, resulting in a notable reduction in production severity events.
  • Enhanced the Reels platform architecture by implementing a configuration system that allows for platform customization on a surface-to-surface basis.
  • Participated in on-call rotation for the main Feed triaging and investigating internally and externally reported bugs - catching increasing crash rates before release, bugs in production that may have led to revenue regressions

  • Led customer information API migration to reduce service calls by 50%, reduce client-side business logic, and simplify storage complexity to one source of truth
  • Owned migration of several app screens to new server-side driven design architecture designed and developed in house
  • Collaborated with data engineers and other platform leads to design consistent specifications for reporting metrics to Adobe in order for product managers to analyze user interactions and make data-driven decisions for app features
  • Acted as release manager ensuring features in development are included in specific production versions, writing customer-facing release notes, and driving the application code through the continuous integration pipeline and into App Store Connect
  • Participated in an on-call rotation that focused on resolving high-severity issues in production code in a hot fix version or by escalating them to the service producing the issue
  • Participated in general agile development processes, including feature, planning implementing new features with co developers, participating in bug bashes, and fixing bugs in testing as well as production code
  • Led initiative to upgrade Kochava SDK in order to attribute new app installs while meeting Apple’s new privacy requirements in iOS 14
  • Designed new architecture to fetch unique identifiers for each third party service Audible utilizes and deliver to their respective targeted endpoints to meet Amazon information security requirements
