About

My focus is on building critical, high-performance systems where reliability is non-negotiable.

With 20+ years of experience in Software Architecture, I have moved from scaling massive Enterprise platforms (Java/Spring, FinTech) to engineering safety-critical, high-performance systems (Rust, Real-time Audio) and cloud-native, serverless architectures (AWS Lambda, Data Processing).

I am seeking high-impact, long-term missions (Freelance or Staff Engineer) in Deep Tech sectors (Space, Energy, Health, High-Frequency Trading).

    Services Offered

    Systems Architecture

    Designing scalable, secure, and maintainable systems, particularly for Deep Tech, SaaS, and High-Performance applications.

    Technical Leadership

    Providing strategic planning, technology roadmapping, and team leadership for scale-ups and mature organizations.

    Hands-on Development

    Expert-level development in Java/Spring, Rust (real-time systems, cloud-native/serverless), and Next.js for complex projects.

    Team Mentorship

    Coaching development teams, instilling best practices, and conducting design and code reviews.

    Technical Consulting

    Auditing existing systems, advising on technical debt, and providing solutions for scaling and performance.

    Experience

    Solo Founder & Principal Engineer
    Tylium
    Oct 2023 – Present

    As my primary ongoing passion project (parallel to my freelance consulting), I am independently architecting and engineering a complete, end-to-end ecosystem for audio/MIDI software, along with cloud-native data processing platforms.

    • High-Performance Rust Backend (Cutoff): Architected and built a large-scale Rust monorepo for real-time audio/MIDI processing, including a VST3 plugin host, a modular event-processing engine, and cross-platform I/O libraries.
    • Cloud-Native Rust Platform (Gitshot, July 2023 - January 2024): Architected and built an enterprise-grade Git repository analytics platform combining Rust ETL pipelines, AWS Lambda serverless functions, and Java/Spring Boot APIs. Designed chunked processing architecture for large-scale repository analysis (Linux kernel, VSCode) using Polars, Apache Arrow/Parquet, and parallel processing with `rayon`. Integrated OAuth2, Stripe billing, and RabbitMQ messaging in a production-ready, polyglot system.
    • Specialized Audio UI Framework: Engineered a performance-first React/TypeScript component library using modern CSS and SVG to ensure fluid rendering under heavy CPU load from audio processing.
    • Full-Stack E-commerce Platform: Built the complete commercial web platform (marketing, blog, e-commerce) using Next.js, Vercel, Stripe, and a serverless Postgres DB.
