Meta

Senior Software Engineer · Ads Ranking Infrastructure

  • Engineered a low-latency, high-throughput frequency capping platform integrated into Meta's final-stage Dynamic Ads ranking stack — processing real-time impression and offsite conversion signals across batch and near-real-time streaming pipelines at massive scale.
  • Designed a policy-driven signal aggregation framework supporting per-user, per-ad, and per-campaign frequency control with dynamic tuning across audience cohorts and signal quality tiers; deployed as a low-latency ranking feature within core ads serving infrastructure without impacting SLAs.
  • Delivered $7M+ annualized iRev by applying quantitative analysis of exposure-frequency curves to calibrate cap thresholds and reduce delivery inefficiency at scale.
  • Architected an LLM-powered internal diagnostic agent using retrieval over operational logs/metrics and structured tool use to accelerate root-cause analysis for ads delivery issues.

Stellar Development Foundation

Senior Software Engineer

  • Architected and developed a new backend system for handling transactions and events in the Stellar RPC service.
  • Re-engineered the RPC service with optimized caching in Stellar Platform — core endpoint latency down 48%.
  • Led platform and SDK releases for enterprise deployments and global developer adoption across the Stellar ecosystem.

Robinhood

Senior Software Engineer

  • Designed and implemented a high-reliability State Machine as a Service platform for financial transaction orchestration (Python, Go, Redis, PostgreSQL, AWS) — engineers deploy complex multi-step transaction flows via JSON config in ~10 minutes vs. multi-week custom builds, with guaranteed state consistency and atomic DB/RPC side effects.
  • Built the core execution engine, transition framework, low-latency caching layer, and durable state store for regulated financial workflows — cutting duplicated engineering effort by ~42%.
  • Drove adoption across 30+ financial product flows — crypto asset launches, onboarding, eligibility checks, multi-step transaction experiences — standardizing orchestration for regulated products and accelerating launches 3–5×.

Dropbox

Software Engineer · Dropbox Spaces

  • Designed and built core collaboration features for Dropbox Spaces, a project-centric virtual workspace for teams (Go, Python, Protobuf, gRPC).
  • Led a 4-engineer team through design reviews, sprint planning, on-call, and cross-functional execution across notifications, membership management, and workspace creation.
  • Developed backend services and APIs integrating with Dropbox identity, sharing, and collaboration systems.

Quantstamp · YC W18

Founding Software Engineer

  • First engineer on the web product team — built the MVP from scratch.
  • Worked directly with the CEO and CTO to build an asynchronous backend so customers could receive audit reports without blocking on submission.

Barclays

Senior Software Engineer · Payments / Fraud / Collections

  • Engineered performance-critical payment, fraud detection, and collections services processing millions of daily financial transactions; owned reliability and latency SLAs for core payment flows (Java, Spring, AWS).
  • Optimized the transaction validation pipeline via async processing and batch handling — 30% latency reduction on the critical payment path.
  • Partnered with data science to refine real-time fraud detection models integrating behavioral signals and transaction history — +25% detection accuracy.
  • Designed rule-based decision engines scoring accounts by risk profile and payment history to maximize collections recovery efficiency.
"Prit was great to work with. He thought thoroughly through his eng designs so we were prepared for complications up front and brought wisdom to our solutions. He also dove deep into difficult problems and worked independently, asking good questions when appropriate. Prit was also a positive influence on the team as he built meaningful personal connections and always maintained an upbeat attitude even when times were tough or uncertain without being fake or disingenuous. This combination of technical expertise and positive influence makes him a great team member!"
— Co-founder & CTO @odo | Ex-Robinhood
"I was the mentor of Prit Sheth in Global Think Tank Innovation Contest held at Barclaycard and run by MasterCard. His ingenious idea of a Smart Recommendation Engine not only became the only project from India to qualify but also won the contest. He has proven himself as an exceptionally committed collaborator who consistently asks questions and seeks guidance when needed, to improve his understanding of the business, technology, and solutions. In the final round, he had pitched his idea to the CEO of Barclaycard US and other executives and Innovation Council. The presentation was very well received. In my time with Prit I observed him as forward thinking yet grounded in the technology that would both limit and enable the solution. He would be an asset to the program and I offer my highest recommendation."
