I am a passionate self-starter with 10+ years of experience designing and delivering cost effective low-latency cloud, mobile and web solutions. I am a team player with a proven track record of delivering quality solutions with a keen interest in distributed low latency systems.
Experience
· Achieved a dramatic 100% reduction in trading platform order execution time from 30 seconds to 5 microseconds through cunning rewrite of the order execution algorithm.
· Standardized order routing algorithm config through trader friendly rule generation UI that reduced by 90% the time to market for new trading strategies with no code changes required.
· Reduced by 80% onboarding time and increased developer velocity by Dockerizing a Python & Java monorepo in devcontainers.
· Led the optimization of an AI inference pipeline for an AI platform. Worked on a custom K8s operator to manage GPU RAM allocation for fleet of artificial neural network (ANN) workers.
· 57% reduction in E2E latency by optimizing architecture & code of the AI pipeline workflow.
· Improved by 95% the pod scale out time via pre-warming of K8s PVC with model metadata.
· Reduced by 94% the CI duration by optimizing the AI image & re-architecting CI/CD pipeline.
· Created cross-platform native conferencing application in C++ with focus on WebRTC network stack and UNIX socket cross-module communication.
· Reduced UNIX TCP sockets network chatter by 55% as tracked by cAdvisor.
· Led team of 4 in planning, architecting & delivering a serverless redemption platform with B2B & B2C API's on Lambda. Delivered on-time with CMS backed white-label ReactJS web.
· Successfully liaised with down-stream systems in integrating a new proxy wrapper to break up a Java monolith. Used Kafka, Docker & TS. Added CI that enabled daily release cadence.
· Designed and implemented plugin based API Gateway internal service. This new integration with downstream vendors reduced cross-team load by 17%.
· Reduced MTTR by 33% by adding monitoring of AKS & Azure Functions via ELK on AKS
· Created magic link sign in/up system rolled out across all company sites increasing customer sign-up completion journey by 32%.
· Setup event-driven ETL pipeline over of TB of customer S3 data lake in PySpark Hadoop. New real-time BI increased customer engagement by 11% through targeted offers.
· Cut down L1 support load by 27% via new ReactJS & Go self-service portal for customers.
· Led team of 3 to create cluster based blockchain ledger platform. Developed on NodeJS, Kotlin & ReactJS running on ECS with self-checkout customer node expansion via Terraform.
· Led & delivered serverless platform digitizing manual tasks of foundation with 50+ clients.
· Managed & developed Workplace NLP bot as L1 support used by 250+ employees. Added ReactJS HR dashboard for human chat escalation, nominations & meeting room bookings.
· Reduced by 90% a 5 days faulty process via an event driven ETL for targeted ad campaigns.
· Consolidated streaming of real-time pricing data to 100's of downstream systems via a low latency asynchronous graph based distributed aggregation system in Java Spring.
· Reduced by 65% testing time of strategic logic by creating generic Cucumber test generator.
· Successfully did fundamental architectural change to major project by replacing duplicate JSP pages with modular Angular web and observer, decorator, adapter based Java backend.
· Reduced team load by 95% on majority of daily tasks via Python and Java automation.
Projects
· Flutter cross-platform iOS, Android & Web app written in Flutter for users mental health.
· Leveraging Firebase Firestore for storage and Cloud Functions for serverless backend.
· CI/CD pipeline in GitHub Actions for testing, building and deployment leveraging FastLane
· Added improvements to Flutter project platform engine and `flutter doctor` tool.
· Contributor across Kubernetes Open Source Project networking and cli SIGs.
· Created software framework with OpenCV and C++ to provide advanced HCI by using hand gestures manipulating digital artifacts with web camera and computer vision algorithms.
· Implemented 3D environment through Irrlicht and C++ with networking and physics for engaging collaboration between multiple remote users in a synchronized environment.
