Zheng Yan (zypeh)

I have built trading systems from scratch twice; one for equities, one for crypto. I'm designing a language with no garbage collector.

Right now I'm measuring how much forest loss the world's satellites can't see.

Then I am going to price it.

I'm building satellite-radar (SAR) intelligence that measures forest carbon risk directly, an independent physical signal for carbon-reversal underwriting.

Software Engineering Consultant

Independent

I built the low latency trading system from scratch colocated in BURSA Malaysia for a boutique proprietary trading firm.

That includes feed parsers, order gateways, signal-to-execution pipelines, and the strategy logic that sits on top accordingly.

WokML

Sole Developer

I'm designing an ML-family language for mission-critical systems, where the compiler erases reference counts at compile time so pure functions mutate in place with no garbage collector, alongside algebraic effect handlers with one-shot continuations.

Past

Balaena Quant

I built zero-syscall massive concurrency trading system for cross-venue cryptocurrency market making system. And I have a talk about it on youtube.

Makasih

My friends and I led a volunteer engineering team to build a geo-routing system that matched pandemic aid requests to volunteers, 200+ matches, local press coverage.

Last-Mile Delivery Optimisation

I built population-weighted distance matrices and DP-optimised stop placement for a government last-mile delivery project, plus neural-net demand forecasting for underserved suburbs.

Unistay

I co-founded a student housing platform that won Startup Weekend KL, got incubated under MaGIC, and placed top 5 at the Digi WWWoW Awards.
