# About Me

Hoa Le

I build high\-traffic backend systems, real\-time data pipelines, CRM/CDP integrations, and developer tools for AI coding agents\.

## What I Do

Most of my day job is building backend systems that do not fall over when traffic spikes\. I spend my time on system design, high\-volume visitor tracking and identity resolution, real\-time data pipelines, data enrichment, and wiring up integrations across CRM, CDP, e\-commerce, and marketing tools so data actually lands where it is supposed to go\.

## Skills \& Stack

- **System Design \& Backends:** High\-concurrency APIs, event\-driven services, and cookie/cookieless identity tracking \(mostly Python, TypeScript, and Node\.js\)\.
- **Data Pipelines \& Enrichment:** Real\-time streaming, large\-scale ETL, and data enrichment using PostgreSQL, Aurora, Kinesis, SQS/SNS, EMR, Glue, and Athena\.
- **CRM, CDP \& Marketing Integrations:** Two\-way integrations with e\-commerce, CRM, CDP, and marketing platforms, including all the weird webhooks, rate limits, and edge cases they throw at you\.
- **Cloud \& Infrastructure:** Running production workloads on AWS and GCP without setting the cloud bill on fire\.
- **AI Developer Tooling:** Spec\-driven workflows and multi\-agent tools that keep coding agents on the rails\.

## Background \& What I’m Into

I have been writing software for over ten years\. I started out in telecom middleware where five\-nines uptime was a real rule, moved into large\-scale data and mar\-tech platforms, and grew into leading architecture and engineering teams\. Even after managing teams, I still love writing code and figuring out why a distributed system is acting weird at 2 a\.m\.

Lately, I spend a lot of my free time tinkering with AI coding agents\. Left alone, AI agents love to guess and rewrite half your codebase, so I built [Specgent](https://www.hoalee.net/specgent/docs/overview) to make them read the repo and follow a clear spec before they touch a single file\.
