Full-stack Engineer building production systems end to end. I combine high-performance frontend engineering with backend architecture that holds under load, including chat infrastructure, background workers, AI pipelines, caching layers, and event-driven workflows.
Developed the complete real-time AI infrastructure for an emotional support agent that leverages multi-modal inputs to detect risk, evaluate mood, and deliver personalized counseling.
- Designed the end-to-end architecture, orchestrating real-time voice streaming (ElevenLabs) alongside dual-model inference (Gemini Flash for rapid scoring, Gemini Pro for counseling).
- Engineered the backend system on Cloud Run, implementing secure session state management, authentication, and persistent storage with PostgreSQL and Drizzle.
- Implemented a multi-stage AI pipeline that performs real-time emotional analysis and risk detection to ensure safety guardrails before generating adaptive voice responses.
- Built the contextual memory engine, utilizing vector embeddings and session summarization to maintain conversation continuity and personalized user history across interactions.

Architected a high-performance, serverless AI companion that transforms raw League of Legends match data into actionable coaching insights using AWS Bedrock and React 19. Delivered the app in a 4-week sprint with a 2-person team.
- Managed the full-stack Turbo Monorepo on AWS SST (Lambda/Node.js 22), achieving <15ms latency for cached operations.
- Built a robust JSON-only architecture with Amazon Nova Micro, utilizing strict schema enforcement and token-optimized prompts to convert complex match logs into machine-readable coaching data.
- Implemented "Graceful Degradation" logic where invalid AI outputs trigger deterministic fallbacks, ensuring 100% UI uptime even during LLM failures.
- Developed a Global Rate Gate middleware to orchestrate Riot API consumption, managing concurrency and quotas across distributed services.
- Implemented on-the-fly social card generation using server-side rendering stored in S3.

Built the full backend and AI orchestration layer for an agentic system that converts raw Asana social-media tasks into validated schedules and repost recommendations.
- Designed the end-to-end architecture, mapping how CSV/XLSX data moves from frontend parsing into backend normalization and finally into the Orchestrate agent.
- Implemented the backend with Hono.
- Integrated IBM watsonx Orchestrate using a custom JSON contract that drives multi-step agent reasoning for captions, validation, post-type classification, and scheduling.
- Built the agent’s knowledge base, combining brand guidelines, product features, rule logic, historical posting data, and a formal prompt spec for deterministic output.
- Delivered the entire reasoning pipeline, ensuring stable, machine-readable JSON for the frontend preview experience.
Stack: Hono, Cloudflare Workers, TypeScript, IBM watsonx Orchestrate
Core engineer for a counseling platform connecting clients with psychologists.
- Built the backend with NestJS and PostgreSQL (Drizzle ORM).
- Added real-time chat with presence, file sharing, and unread tracking using Ably.
- Integrated Zoom automation, notifications, and background jobs with Bull + Redis.
- Containerized and deployed the app on GCP Cloud Run using Docker.
- Added retry logic and monitoring to background tasks.
Stack: NestJS, PostgreSQL (Drizzle), Redis, BullMQ, Ably, React
Worked on the frontend for an AI-powered translator that converts Malay Sign Language into text in real time.
- Built a responsive gesture recognition interface using TensorFlow.js and MediaPipe.
- Integrated PAN AI LLMs for contextual text generation and improved translation accuracy.
- Deployed via GCP Cloud Run for seamless browser-based interaction.
Stack: React, TensorFlow.js, MediaPipe, GCP, PAN AI LLMs
