Personal Statement

Informatics graduate transitioning into software engineering and AI/ML development, with nearly 4 years of hands-on experience across chatbot systems, LLM quality evaluation, and data operations. Currently building independent projects spanning RAG pipelines, intent classification, and NLP benchmarking — applying machine learning and full-stack engineering to problems I find genuinely worth solving. My background bridges technical depth and product thinking: I understand how AI systems behave in production, how quality breaks down, and how to close that gap through engineering. I am actively growing toward roles in Data Science, AI Engineering, and product-driven software development, and I am eager to contribute and accelerate that growth within Apple's innovation ecosystem.

Work Experience
Full-Stack Developer Trainee
Feb 2026 – Apr 2026
Korea-ASEAN Digital Academy (KADA) — AKCF · NIPA · Komdigi · Elice Inc.
  • Selected as one of 60 participants from over 900 applicants for a fully-funded program covering Full-Stack Development, AI/ML, Cloud Services, DevOps, and AI Ethics.
  • Took the Backend Developer role for CineTrack (cinema analytics platform) and Yorindo (event ticketing system) within cross-functional capstone teams; built REST APIs and backend services using Fastify on Node.js with PostgreSQL and Redis caching. CineTrack API  ·  CineTrack Frontend  ·  Yorindo
  • Designed SQL analytics pipelines for revenue, occupancy, and demand-pattern insights, and integrated LLM-powered features to surface business insights from operational data.
  • Applied Agile and AI-augmented SDLC practices: defined epics, wrote user stories, broke down sprint tasks, and delivered through architecture, implementation, testing, and demo within a 2-month timeline.
Chatbot Quality Assurance Analyst
May 2024 – Oct 2025
PT Fliptech Lentera Inspirasi Pertiwi (Flip)
  • Evaluated production LLM/RAG chatbot systems through structured sampling (prompt accuracy, response grounding, hallucination detection, retrieval effectiveness) and analyzed weekly and monthly interaction data to identify user behavior patterns, knowledge gaps, and system failure modes.
  • Conducted quality reviews of ML-powered features including intent classification, sentiment analysis, and OCR, through accuracy analysis, confidence threshold evaluation, and failure-case investigation.
  • Collaborated with AI Development and Product teams to translate root-cause findings into prompt restructuring, fallback handling, and knowledge base improvements.
  • Built and maintained KPI dashboards (CSAT, fallback rate, hallucination rate, intent accuracy) that guided iteration priorities across release cycles; contributed to outcomes of 65% CSAT, 3% fallback rate, and unidentified utterances below 12%.
IT Operational — Chatbot & Omnichannel Development
Dec 2021 – Apr 2024
PT Infomedia Nusantara (Telkom Group)
  • Supported chatbot and omnichannel platforms serving approximately 1,000 daily customer interactions across CRM and customer-service channels.
  • Designed and developed intent classification systems and rule-based chatbots, including intent architecture, training data preparation, conversation flow design, NLP platform configuration, and post-deployment optimization.
  • Coordinated SIT/UAT activities and system integration assurance across third-party APIs (Meta/WhatsApp, omnichannel CRM), reducing post-deployment defects.
  • Analyzed interaction data to identify usage trends and automation opportunities; conducted root-cause analysis that informed chatbot rule updates and service improvements.
  • Conducted root-cause analysis of operational and performance issues, translating findings into chatbot enhancements, intent refinements, and conversation flow optimizations to improve service effectiveness and customer experience.
