Hi, I'm Zhafira / Fira!

Architecting large-scale game analytics and backend systems across PostgreSQL, SQL Server, C#, Redis, and production monitoring. Recent work includes pipelines processing 900M+ time-series records annually, bulk aggregation jobs with ~100× speedups, cross-platform game analytics APIs, and resilient distributed worker infrastructure.

Designed and prototyped intelligent in-game agents for RPG environments, including companions, enemies, and bosses. Worked on FSM- and RL-based decision systems, adaptive combat behaviors, simulation environments, and runtime profiling for large-scale encounters.

Worked across deployment, DevOps, backend, and full-stack software engineering for Palantir Peptides, a platform for collecting and growing self-reported peptide research data. Responsible for production deployment and platform engineering across the application stack.

Built and refined hotel-data pipelines, scraping infrastructure, vector-database architecture, embedding workflows, and clustering systems for semantic search and intelligent recommendations.

Developed ETL pipelines and a data-lake architecture across multiple data sources, with stakeholder-facing API dashboards and operational observability.

Led a 14-person intern team delivering weekly Data & AI projects, including sentiment analysis, competitor intelligence, ML-Ops suitability assessment, and property-price prediction pipelines.

Worked on fraudulent-transaction monitoring and data transformation, improving transaction-checking accuracy to above 85% while supporting operational response workflows.
