Algorithmic Trading Systems

MQL5, MQL4, PineScript, MetaTrader 4/5, TradingView

A portfolio of algorithmic trading systems built for Forex markets, ranging from scalping strategies to longer-term position management

The most architecturally complex is a three-file coordinated trading system: a symbol scanner capable of monitoring 3000+ simultaneous trading pairs, a signal evaluation engine that assesses entry conditions for both long and short positions, and a position management system that dynamically handles open trades - adjusting take profits, managing risk exposure and evaluating exit conditions against live market logic.

Additional work includes multiple independent scalping Expert Advisors for MT4/5, MQL4 to MQL5 conversion projects and PineScript strategy development on TradingView

One EA is publicly available on the official MQL5 marketplace.

Will of the Mountainhopper - Game Demo

GameMaker, GML

A 2.5D adventure RPG currently listed on Steam, built as contracted work over the course of a year alongside a collaborating developer. All systems were written in GML code - no visual scripting or node graphs were used.

My contribution focused on the game systems and UI architecture: a complete save and load system built on manually serialized JSON-like data structures with boolean state tracking across rooms, an inventory system, a crafting system, weapon quickslots, a proximity-based interaction system displaying up to five simultaneous contextual prompts depending on nearby interactable objects, NPC dialogue using the same interaction architecture, and puzzle design across multiple rooms.

The project was contracted work, paid monthly, delivered over more than a year. The game has since continued development beyond our contribution and remains an ongoing project. The demo is publicly available on Steam.
