KIEN PHAMCAPITAL & QUANT LABS

Tech Arsenal & Toolchain

The production tools behind the research, with the trade-offs that decided each one.

Quantitative Modeling & Core Analytics

Python3.12

Model research, prototyping, orchestration glue

95% track record
Rationale: Ecosystem breadth outweighs raw speed for iterative modeling.
Polars1.9

Tick-level data transforms and joins

88% track record
Rationale: Selected over Pandas for 15x memory efficiency in tick-level simulations.
NumPy2.1

Vectorized numerical kernels

92% track record
Rationale: Baseline computational standard for contiguous memory matrices.
C++C++20

Backtesting engine hot path

78% track record
Rationale: Python overhead was unacceptable inside microsecond tick fill loops.

Data Pipeline & Server Infrastructure

Docker27

Reproducible research environments

85% track record
Rationale: Eliminates environment drift between desk laptop and remote compute nodes.
Airflow2.10

Nightly pipeline orchestration

80% track record
Rationale: Chosen over cron for automated retries, backfills, and DAG visibility.
PostgreSQL16

Research warehouse & time-series features

90% track record
Rationale: Strong window functions and relational auditability.
