Hai Tran Ngoc · Applied AI Engineer

I built Recoder to turn a puzzle game's reference data into a playable, testable Unity build in about eight hours.

It automates most of the reconstruction workflow: grounding AI agents in real project evidence, rebuilding gameplay in dependency order, and checking candidate behavior against runtime traces.

One flagship system—and the story behind it.

01 · Flagship

Recoder

AI-assisted game regeneration system

Grounds agents in real project evidence, coordinates engineering tools, checks runtime behavior, and produces testable builds.

Result: 4–5 generated games, 2 released to stores.

Company experience

Systems I built around real operating workflows.

The work is described by problem, contribution, and outcome—without exposing company data or proprietary implementation details.

01
#UserAcquisition#CreativeOps

Creative distribution automation

Built a unified workflow that reads creative assets from shared storage, applies naming and mapping rules, and prepares bulk delivery to Google Ads and Unity Ads. AI is used only for tasks that need judgment—such as generating ad copy or identifying a creative type—while deterministic steps stay rule-based for speed and reliability.

Contribution: workflow design, platform integrations, batch processing, and review-ready outputs.

#ASO#Publishing

Store localization & publishing

Automated the path from localized metadata to draft submission on Google Play and App Store Connect. The workflow handles store-specific constraints, including API permissions, metadata and asset upload, and Apple version creation before localization.

Contribution: API integration, AI-assisted metadata generation, versioning rules, and safe human review gates.

#GameDesign#PlayableAds

Playable & level-generation tools

Built tools to inspect and modify playable ads, replace assets and store links, edit board data, and verify the final render. I also designed level-generation workflows for tile- and arrow-based puzzle games so designers could create and test content faster.

Contribution: tooling architecture, runtime hooks, AI-facing tool interfaces, and automated verification.

#PeopleOperations#HR

AI workflows for People Operations

Designed AI-assisted workflows across recruitment, onboarding, internal knowledge, contracts, attendance, payroll, reminders, and offboarding. The system follows deadlines, drafts routine content, detects missing or unusual cases, and escalates work while keeping final decisions with HR.

Contribution: workflow modelling, agent boundaries, SLA and escalation rules, and human-in-the-loop design.

#BI#DataEngineering

Data platform & large-scale crawling

Contributed to production pipelines that bring RevenueCat and Adjust data into BigQuery for reporting and analysis. I also worked on large-scale crawling flows, data normalization, scheduled processing, and quality checks so downstream teams could rely on consistent datasets.

Contribution: ingestion pipelines, orchestration, data validation, and operational monitoring.
