AI Engineer Intern

May 2026 - Jul 2026 · 3 mos

AI Singapore · Internship

As an AI Engineer Intern at AI Singapore, I built agentic document understanding systems for CSIT — orchestrating open-source vision-language models into a layout-aware parsing pipeline, and building the evaluation harness to prove it actually worked. This was my first deep dive into agentic systems and LLM evaluation, and it taught me how much of AI engineering is really about measurement, guardrails and knowing when a model is quietly wrong.

  • Engineered an agentic document parser for CSIT orchestrating 23 open-source OCR and Vision-Language-Models (GLM-4.6V, Qwen3-VL) through layout-aware, region-level tool dispatching.
  • Engineered a self-improving evaluation harness pairing cross-family VLM-as-a-Judge scoring with deterministic guardrails and short-term memory with robust regression test coverage.
  • Deployed on-prem using oMLX instrumented with OpenTelemetry/Arize Phoenix tracing and rigorously A/B tested agentic variations against deterministic baselines.

Software Engineer Intern

Sonzai Labs · Internship

As a Software Engineer Intern at Sonzai Labs, I contributed to the development of the startup's flagship game, "Telemafia", as an engineer working directly on production. I engineered scalable features, high-performance data pipelines and UI UX while ensuring production stability through rapid bug resolution on CI/CD workflows. As my first internship, I learned what taking ownership really means, had to adapt fast to new technologies on the fly, and grew a lot as a software engineer — it was intense, insane, and genuinely one of the most fun learning experiences I've had!

  • Created clan systems on both frontend and backend using Go and RESTful APIs, optimizing atomic CQL queries for ScyllaDB while implementing Redis caching for high-concurrency performance.
  • Engineered core gameplay UI UX production features, UI screen responsiveness, game state management (Zustand) and internationalization (i18n) strategies to support global users using React, Typescript and TailwindCSS on the frontend.
  • Led frontend development for Sonzai's NFT minting event, integrating smart contracts, Web3 wallet authentication while configuring Cloudflare (WAF/Rate Limiting) to mitigate DDoS and XSS attacks; launched and minted 500 NFTs.
  • Engineered an automated leaderboard and data reconciliation system using Python on Windmill Orchestrator, utilizing Apache Pulsar (Pub/Sub) and ScyllaDB for real-time processing.
