You will get a Python ETL pipeline to extract, clean, and load your data
Project details
You will get a reliable, automated Python ETL pipeline that extracts
your data, cleans it, and loads it exactly where you need it.
I have 3+ years of experience building data pipelines for production
environments — from simple file transformations to multi-source pipelines
feeding PostgreSQL and analytics systems. My background in quantitative
data processing means I build for accuracy and reliability, not just
functionality.
If your team is still moving data manually between systems, I'll fix that.

About Watcharasak
Python Automation & Data Pipeline Engineer
Bangkok, Thailand - 4:26 pm local time
wrong time, pipelines that fail silently, scripts no one else can
maintain. I build systems that don't.
My background is in quantitative trading infrastructure, where data
reliability isn't a nice-to-have — it's the whole point. I've built
production pipelines processing over a million records daily and
automated workflows that cut a 10-person team's manual workload by 70%.
That same standard is what I bring to every freelance project.
What I work on:
Python automation — scheduled scripts, file processing, report
generation, workflow automation across APIs and databases.
ETL & data pipelines — end-to-end extraction, transformation, and
loading from messy real-world sources into clean, usable formats.
SQL analysis & optimization — complex queries, slow query fixes,
reporting layers on top of existing databases (MySQL, PostgreSQL).
Data cleaning & transformation — turning inconsistent, multi-source
datasets into something analysis-ready.
I work best with clients who have a specific problem and want it solved
properly. Every delivery comes with clean code, documentation, and a
handoff you can actually understand and maintain.
Available for fixed-price projects and hourly engagements.
