Oung Seik Nyan

Backend & Systems Engineer

Backend engineer building automation platforms and distributed systems.

I’m Oung Seik Nyan, also known as Min Aung Thu Win, a backend and systems engineer specializing in automation platforms, real-time systems, and developer infrastructure. I focus on backend architecture that removes manual work and makes complex operations reliable.

  • Built a distributed mobile device farm for Android and iOS testing.
  • Developed a shipping automation platform for e-commerce operations.
  • Designed real-time and AI-powered backend systems.

System Snapshot

What I optimize for

Global-ready

Automation

Systems that remove setup friction and reduce repetitive operational work.

Real-time control

Monitoring, orchestration, and event-driven communication across services.

Architecture

Clear service boundaries, reliable workflows, and systems that scale without excess complexity.

Developer tooling

Internal platforms and workflows that improve team velocity and maintainability.

Current Focus

Distributed systems Automation platforms Real-time orchestration Type-safe APIs AI backends

Selected Work

Selected backend engineering projects in automation, orchestration, and reliability.

These are the strongest examples of the kind of systems I want to keep building: real products with operational constraints, measurable impact, and clear backend ownership.

01 / Distributed Device Farm

Test Canvas

A platform that automates mobile testing infrastructure by eliminating manual device setup.

  • Designed a distributed system to manage Android and iOS devices across multiple servers.
  • Automated Appium and Selenium setup per device for plug-and-play testing.
  • Implemented real-time monitoring, screen streaming, and access control.

Impact

  • Reduced QA setup time from ~30 minutes to near zero.
  • Enabled parallel testing across 10+ devices.
  • Improved reliability for repeated mobile test execution.

02 / Shipping Automation Platform

Bookogsend

A shipping platform enabling e-commerce businesses to automate logistics across multiple providers.

  • Integrated shipping providers including GLS and TeamJK.
  • Built a WooCommerce plugin for automatic order synchronization.
  • Designed reconciliation, inventory, and payment workflows for merchants.

Impact

  • Reduced manual shipping operations for merchants.
  • Enabled scalable multi-provider logistics integration.
  • Improved day-to-day operational efficiency.

03 / AI Data Interface

SQL Agent

A microservice that lets users query relational databases with natural language.

  • Built an LLM-powered query system using LangChain.
  • Designed a FastAPI service for orchestration and query execution.
  • Generated charts and structured outputs for analytical workflows.

Impact

  • Enabled non-technical users to analyze data without writing SQL.
  • Reduced the need for manual reporting queries.

Architecture Signal

Test Canvas system flow

A simple diagram does a lot of work on a portfolio site. It signals system design thinking, operational awareness, and the ability to communicate architecture clearly.

05

UI

Devices are coordinated by a central service, queued for execution, processed by workers, and exposed through a monitoring interface for operators.

Engineering Focus

The backend problems I’m best suited to solve.

Distributed systems

Service boundaries, orchestration, and operational reliability.

Real-time backend systems

WebSockets, device coordination, monitoring, and event-driven flows.

Developer tooling

Internal platforms that remove manual setup and improve delivery speed.

Type-safe APIs

Modern TypeScript systems with predictable contracts and maintainable code.

AI-assisted backends

Practical interfaces that connect LLM workflows to business data.

How I Think

I focus on systems that reduce manual work and improve scalability.

I enjoy turning operational complexity into simple, reliable workflows. The goal is usually the same: fewer fragile steps, clearer abstractions, and a system teams can operate with confidence.

I keep the portfolio short here. The detailed history belongs in a resume; this page should make the direction of my work immediately obvious.

GitHub / Building

I actively build tools and explore system design, backend architecture, and developer infrastructure.

GitHub is where I keep shipping. The blog is where I can make the architecture and decision-making more visible.
