About Me

A little bit about who I am

Profile photo of Arry Pandowo

Backend Software Engineer @ Cinema XXI

I'm a Backend Software Engineer with 5+ years of experience building robust, scalable backend systems. I specialise in Java / Spring Boot and Go, with hands-on experience designing RESTful APIs, microservices, and event-driven architectures.

Currently working at PT Nusantara Sejahtera Raya — Cinema XXI in Jakarta, maintaining and evolving the core microservices of the MTIX ticketing platform. Previously at Infosys leading a full digital banking codebase refactor, and at PT Sarana Multigriya Finansial as an IT Analyst designing core system architecture.

Before pivoting into engineering, I spent over 7 years in financial services — in credit risk analysis, regulatory compliance, and mortgage operations. That analytical foundation now directly shapes how I reason about data, design systems, and translate business requirements into code.

Forex Auto Trader
What it does

Python engine bridging to MetaTrader5 via TCP. Five concurrent threads handle tick-level entry signals (100ms), session-dispatched position monitoring, candle-based regime classification, and event-driven risk control — zero human intervention during a session.

Goals

Validate tick and candle-based Gold (XAUUSD) scalp strategies through a cursor-driven backtest engine, then deploy live once consistently profitable. Current active stack: TickTrial1 strategy + MonitoringTrial4 with FVG & ICT Fibonacci analysis.

Private repo — not yet consistently profitable
