Über Begatim

Ich helfe Teams, Anwendungen messbar schneller und skalierbarer zu machen – durch Performance Optimierung, Parallel Programming und saubere Software Engineering-Praxis. Typische Einsätze: Bottlenecks finden (Profiling/Tracing), Latenzen senken, Durchsatz erhöhen und Kosten reduzieren – vom Algorithmus bis zur Architektur.
Leistungen:

Performance-Analyse, Benchmarking, Load/Stress-Tests, Tuning (CPU/RAM/I/O)

Parallel programming (z. B. Task-/Threading, SIMD/Vectorization, verteilte Workloads)

Back-End development (API-Design, Datenzugriff, Caching, Observability)

Front-End development (Rendering-/Bundle-Optimierung, Core Web Vitals, UX-Performance)
Ich arbeite strukturiert mit klaren Metriken (Before/After), reproduzierbaren Tests und pragmatischen Verbesserungen, die im Betrieb stabil bleiben. Kurz: schnelle Software, sauber geliefert.

    • • JobMon Backend (Go): Core developer of a production monitoring service; optimized InfluxDB and PostgreSQL performance through query tuning and intelligent caching strategies.
    • • JobMon Frontend (TypeScript, React, Next.js): Core developer; im proved dashboard rendering performance through metric catego rization and migrated the UI to ChakraUI v3.
    • • IFOS3D (C/C++): Improved computational efficiency and redesigned parallel I/O routines, enabling full overlap of computation and I/O and significantly reducing simulation turnaround time.
    • • CPV (Bash): Contributor to the Cluster Performance Verification benchmark suite; integrated IO500, DLIO, and elbencho to validate storage and AI-relevant workloads.
    • • IOAS (Go): Designed and implemented a cluster-wide I/O monitoring tool that detects excessive usage patterns and automatically notifies users.
    • • Designed and executed comparative benchmarks for time-series databases (QuestDB vs. InfluxDB) to guide backend technology de cisions.
    • • PMFRG (Julia): Implemented performance optimizations that achieved near-linear scaling across increasing core counts.
