Systems Consultant · Technical Author · P99 CONF Speaker
Low-latency, high-throughput systems & concurrency.
Most software fails under load not because of programming languages,
but because concurrency, unbounded queues, and tail
latency are misunderstood.
I help you build architectures that prioritize mechanical sympathy
and deterministic testing,
and I teach engineers how to program reliable concurrent systems.

3-Book Series · Early Access
One Thread, Many Tasks
Build a concurrency runtime from scratch. Understand async/await and coroutines inside out.
A hands-on book series for systems programmers. Build a working concurrency runtime one piece at a time, with a deterministic scheduler and tracing.
Take Turns
Make two jobs share a single thread, remember their progress across steps, and build the scheduler that runs them.
State Machines · Steps · Scheduling
Wait Without Blocking
Add timers, events, and bounded channels so tasks can wait and wake up while other work carries on.
Asynchrony · Channels · Backpressure
Tasks Working Together
Compose larger concurrent programs with futures, actors, pipelines, cancellation, and predictable shutdown mechanisms.

How We Can Work Together
Whether your team is diagnosing a tail-latency bottleneck under heavy load, leveling up on concurrent systems design, or commissioning deep technical writing for senior developers.

Low-Latency & High-Throughput Consulting
When traffic spikes expose unbounded queues, lock contention, or tail-latency death spirals, generic tuning won't fix the root cause. I help teams re-architect critical paths for predictable P99 latency and fault tolerance.
- Backpressure, load shedding & queue architecture audits
- High-throughput backend engineering & performance tuning
- Shared-nothing concurrency & deterministic testing design
Concurrency & Systems Engineering Training
Equip your senior engineers with systems thinking. I run bespoke, code-first workshops that demystify concurrency models, multi-core execution, memory layout, and resilient distributed systems.
- Async runtimes, coroutines, channels & state machines from first principles
- Programming for Multi-core computers
- Custom hands-on exercises tailored to your production stack
Deep-Dive Technical Content & Narratives
Developer tools and infrastructure companies hire me when surface-level content isn't enough. I write authoritative articles, guides, and educational series that earn the trust of skeptical senior engineers & CTOs.
- In-depth architectural essays, benchmarks & reference tutorials
- Multi-part learning series and video/course curricula
- Clear explanations of complex runtime & software internals
Keynotes, Conference Talks & Podcasts
I speak at engineering conferences and industry forums — including P99 CONF and JSConf — on escaping the concurrency trilemma, building reliable distributed systems, and practical performance engineering.
- Featured speaker at P99 CONF 2026, JSConf Colombia & KubeHuddle
- Talks on concurrency, fault-tolerance & system reliability
- Guest appearances on engineering podcasts and livestreams
