Let’s talk

CODE × CRAFT × CURIOSITY

From a first line.
To a working idea.

A personal space for building, exploring
and figuring things out.

HELLO, I’M CHOTIKORN

I build for the web.
And learn by
getting into it.

A Computer Science student who likes the whole picture: the interface, the code, and what happens after you click.

Personal projects in web development and AI. Four months of development, testing and support with the Synerry team.

4 MONTHS · INTERNSHIP COMPLETED

From building my own projects to supporting real systems with a team. A completed four-month internship at Synerry, contributing to web development, testing, and support across multiple projects.

01

Development & support

DEVELOPMENT

Contributed to targeted frontend, backoffice, and API improvements: data visibility, search behaviour, content presentation, and interface refinements.

02

Testing & verification

TESTING

Supported acceptance testing across public pages and admin flows. Recorded reproducible issues, expected behaviour, and regression checks for the team.

03

Investigation & release support

REVIEW

Assisted with investigating application behaviour, reviewing changes, and checking readiness around releases under the team’s established workflow.

04

Documentation & handoff

DOCUMENTATION

Prepared test reports, case summaries, and handoff notes so findings, verification steps, and remaining work could be followed by other team members.

A CLOSER LOOK

Small details.
Useful lessons.

Selected examples of the work I supported.

01

From upload to saved record.

Tested import workflows through file preview and saving. Checked reference data and recorded differences in validation and displayed totals for the team to follow up.

02

Find a country. By code or name.

Contributed a change to backoffice country search so a query could match a country code or its name, then prepared the change for development testing.

03

What happens after you click Save?

Helped test website themes, news modules, special pages and public-information pages. Followed edits from the CMS to the public site, including ordering, visibility, links and desktop/mobile presentation, and documented results for handoff.

04

Making content ready to be heard.

Supported read-only analysis of news content for text-to-speech planning. Distinguished stored HTML from visible text, estimated the likely processing volume and documented the limits of the estimate.

05

When a list and its export disagree.

Investigated differences between filtered records and exported results, tracing how filters passed from the screen to API queries. Documented findings and the database checks still needed before claiming a fix.

BEHIND THE WORK

A person.
Not just a portfolio.

Chotikorn Sittakornkowit
CHOTIKORN SITTAKORNKOWIT Also known as Peter.

Curious about how
things come together.

I’m Chotikorn, also known as Peter, a Computer Science student at Phetchabun Rajabhat University. I enjoy connecting design and engineering—building web experiences, exploring AI and mobile applications, and understanding the systems that support them.

Also exploring IoT, networking, and database management. I value problem-solving, logical thinking, adaptability, and learning by doing.
