| Cybereason | - CR1. I designed and developed custom metrics, significantly improving observability across 3,000 servers, which enhanced troubleshooting efficiency and reduced Mean Time to Resolution (MTTR) by 50% for enterprise customers.
- CR2. I analyzed thread dumps and heap dumps to troubleshoot a critical server issue involving 2,000 concurrent threads, successfully resolving critical availability issues and enhancing system reliability for an enterprise customer with 100,000 employees.
|
| Eukarya | - EU1. I developed a processor that compiles user scripts (Python, Go, Rust, etc.) into WebAssembly files and executes them efficiently on a WASM runtime. This significantly enhanced system extensibility, allowing users to customize their workflows with preferred scripting languages.
- EU2. I developed a real-time logging system for the workflow engine, efficiently leveraging storage (GCS) and cache (Redis). This provided users with real-time visibility into worker execution status, significantly improving monitoring efficiency.
|
| LayerX | - LX1. I developed an event-driven notification system designed to operate securely within a closed network environment. This enabled secure and scalable workflow notifications while ensuring full compliance with high-security standards.
|
| enechain | - EN1. I developed a generator tool for Kubernetes manifests and Terraform configurations for new microservices. This streamlined the deployment process, achieving a 90% reduction in the initial setup and deployment time.
- EN2. I developed a system for local development by deploying Telepresence to the Kubernetes cluster, which accelerated local development cycles and led to a 15% improvement in microservice development speed.
|
| Industry Technology | - IT1. I designed Service Level Indicators (SLIs) and Objectives (SLOs), and developed custom metrics and tracing to significantly enhance system reliability. This strengthened customer trust, directly leading to securing a major enterprise contract.
- IT2. I developed a group chat service and a notification system enabling users to exchange photos, videos, and text messages. This improved user engagement and productivity by 25% by providing a seamless chat experience.
- IT3. I tuned database indexes and optimized queries, significantly improving database performance. This reduced slow query occurrences by 70% and stabilized peak-hour performance.
- IT4. I led the migration from a modular monolith to a microservices architecture to enhance system scalability. This distributed traffic for core features across microservices, reducing the write load on the main database.
- IT5. I managed the migration from MySQL 5.7 to MySQL 8.0 to ensure long-term system reliability and maintainability, which resulted in a 20% increase in query performance.
|
| Algomatic | - AL1. I developed a serverless training pipeline for fine-tuning Large Language Models (LLMs). This new pipeline enabled efficient fine-tuning while significantly optimizing compute resource utilization and reducing overall training costs.
|
| Gunosy | - GU1. I analyzed data from millions of users and designed A/B testing strategies that successfully improved user retention. These improvements to the new user experience led to a 10% increase in 7-day user retention.
