Project

Company Project
Cybereason
  • CR1. I designed and developed custom metrics to improve observability across 3,000 servers, which cut problem resolution time by 50% for enterprise customers.
  • CR2. I troubleshot and fixed a critical server issue with 2,000 concurrent threads, which resolved crashes affecting an enterprise company.
  • CR3. I fixed a critical bug in the core API that required thorough testing across various versions and feature flags, which restored the correct Malop status for millions of endpoints.
Eukarya
  • EU1. I developed a processor that compiles user scripts into WebAssembly and executes them on a WASM runtime, which enabled users to customize workflows efficiently.
  • EU2. I developed a real-time logging system with efficient storage and cache, which enabled users to monitor the workflow status instantly from the UI.
LayerX
  • LX1. I developed a scalable notification system, which allowed a financial institution to track the workflow status, ensuring compliance with high-security standards
enechain
  • EN1. I developed a generator tool for Kubernetes manifests and Terraform configurations for microservices, which reduced initial deployment time by 90%.
  • EN2. I set up a local development environment by deploying Telepresence to the Kubernetes cluster, which accelerated local development for highly dependent microservices.
Industry Technology
  • IT1. I designed SLIs/SLOs and developed custom metrics and tracing to improve reliability, which built customer trust and won us a major enterprise contract.
  • IT2. I developed a group chat service and notification system that support texts, photos, videos, and PDFs, which helped increase user engagement and productivity.
  • IT3. I solved a performance issue with the database by optimizing indexes and queries, and by using caching, which reduced slow query occurrences by 70%.
  • IT4. I migrated from monolith to microservices architecture using a BFF layer to ensure no downtime, which improved system scalability and reduced database load.
  • IT5. I led the migration from MySQL 5.7 to 8.0 and managed an incident during the process, which improved query performance by 20%.
Algomatic
  • AM1. I developed a serverless training pipeline for fine-tuning LLMs, which significantly reduced training costs.
Gunosy
  • GU1. I analyzed data from millions of users and designed A/B testing, which improved 7-day retention by 10%.
