Adrian Bercovici — Co-Founder

Senior Software Architect | Specialized in System Migrations, Decoupling & High-Performance Prototyping I help organizations solve complex architectural bottlenecks. My expertise lies in the "Zero-to-One" phase of high-performance systems: taking abstract requirements and turning them into decoupled, scalable, and benchmarked reality. I am typically brought in to lead system rewrites, monolith-to-microservices migrations, and the rapid prototyping of core distributed engines. 🎯 What I Do Best - System Decoupling & Abstracting: Expert at untangling legacy dependencies and implementing clean, Domain-Driven Design (DDD) boundaries. - Rapid Prototyping: Building production-ready "core engines" from scratch, such as real-time audio pipelines or high-throughput scoring APIs. - Performance Benchmarking: Rigorous load testing and optimization to ensure systems handle extreme scale (e.g., 4,000+ req/s at 25ms p99) before they hit production. - Architectural Strategy: Selecting the right primitive for the job—whether it’s Actor Models (Orleans, Kameo, Erlang/OTP) or workflow orchestration (Temporal.io). 📈 Highlighted Projects - Legacy Transformation: Re-Architected a fintech payment engine, achieving a 25x throughput improvement through strategic decoupling and actor-model implementation. - Greenfield Engineering: Designed and built a real-time DAW SaaS backend using a decoupled actor-based architecture for high-concurrency audio control. - Scalable Messaging: Built clustered WebSocket servers and event-driven platforms with robust conflict resolution. Currently accepting contracts for system design, migrations, and prototyping. Contact: bercovici.adrian.simon@gmail.com
