Hi,

My name is

Aung Lin Htet

AI Developer/Web Developer/Solopreneur · Building Products Solo

Building AI tools, web apps, and automation systems — and posting the whole journey online. My goal: become a solopreneur who ships full products solo.

SP Computer Engineering graduate · GPA 3.86 · AI intern at Tiny Equation · SUTD CSD Sep 2026

Three ways I build.

01

AI Builder.

RAG systems, LLM workflows, agent-based tools, and AI apps — built from scratch, not just configured.

02

Software Developer.

Full-stack web apps, APIs, automation pipelines, and deployable products.

03

Content Creator.

Personal development content on YouTube, Instagram, and TikTok. On hiatus — restarting September 2026.

Journey

Where I've been, what I've built.

Education, work, and personal projects. Still in the journey.

Computer Engineering Student

Singapore Polytechnic

EducationApr 2023 – Mar 2026

Computer Engineering diploma across 6 semesters — building projects in AI, software, cloud, embedded systems, and data. Graduated with a GPA of 3.86 / 4.0.

Personal Development Content Creator

YouTube / Instagram / TikTok

PersonalApr 2025 – Apr 2026

Shared personal development, productivity, and learning content across YouTube, Instagram, and TikTok under The ALH Studio brand. On hiatus since April 2026 — restarting when university begins in September 2026.

System Engineer Intern

Gold Lite

WorkSep 2025 – Feb 2026 · 22 weeks

Built an automation system that replaced a manual DICOM medical image migration workflow — reducing an estimated 1,000 days of manual work to a fully automated pipeline. Delivered within 45 days including development, testing, and handover.

AI Intern / AI Developer

Tiny Equation

WorkOct 2025 – Present

Contributing to a SUTD-incubated AI startup — working on RAG systems, AI agents, LLM-based automation tools, retrieval logic, prompt design, and evaluation workflows. Last project: multi-agentic architecture for a math problem-solving agent (v1).

Web Developer / Co-founder

L&L Service + Freelance

WorkApr 2026 – Present

Co-founding L&L Service alongside a business partner — handling all development while they manage the business side. Also taking on freelance client website projects, built end-to-end with Claude Code.

Bachelor of Engineering — Computer Science & Design (CSD)

Singapore University of Technology and Design (SUTD)

UpcomingSep 2026

Enrolling in SUTD's CSD programme — an 8-term degree combining algorithmic thinking, software engineering, and design principles to build need-driven computing solutions.

AI Projects

I build AI systems, not just use them.

Practical AI systems using LLMs, RAG, multi-agent architectures, and full-stack patterns — not wrappers.

“Anyone can use AI tools. I'm learning to build them.”
