I am a Full-Stack Developer specializing in building web, desktop (Windows), and Android applications with strong capabilities in AI and Machine Learning integration. I help clients turn ideas into real working systems, from simple applications to complex data driven and intelligent solutions. My approach combines practical software development with applied research and data driven methods to deliver efficient, scalable, and modern systems. My expertise includes: Web, Desktop, and Android application development AI-powered systems and Machine Learning integration API development and system integration Database design (SQL/NoSQL) Automation and data-driven applications System architecture for scalable solutions With a research-oriented mindset, I am able to design and implement intelligent systems based on data analysis, modeling, and optimization while keeping solutions practical and aligned with real-world needs. I focus on delivering: ✔ Clean, reliable, and maintainable code ✔ Scalable and high-performance systems ✔ AI-driven solutions that provide real value Let’s discuss your project and turn your idea into a working solution.
IT was my first time working with pyramidexpert but he complete the project on time communicate with you all the way very processional

pyramidexpert goes beyond what is required. The posted project was VERY loosely defined and understandably took a wrong direction. Provider pyramidexpert still worked diligently to rectify what was a miscommunication problem (my fault due to the loosely defined project).I will be continuing with the second stage with pyramidexpert due to past experience.Very good provider.

A2C Optimization with Policy Gradient and DQN for Forex Prediction
2023
IEEE International Conference on Smart Technology (ICE-SMARTec)
This study applies deep reinforcement learning using an Advantage Actor-Critic (A2C) model for forex trading strategy optimization. By combining Policy Gradient (Actor) and Q-learning (Critic), the model adapts to market volatility and improves trading decisions. Experiments on EURUSD data show increased returns, reduced drawdown, and improved Sharpe ratio, demonstrating a robust and effective approach for financial trading.

Multi-Critic DDPG for Forex Trading with Macroeconomic News Selection
2025
Computational Economic (Scopus)
This study proposes a reinforcement learning-based forex trading model using Multi-Critic Deep Deterministic Policy Gradient (MC-DDPG). The model integrates historical data, technical indicators, and macroeconomic news to improve profitability while controlling risk. Backtesting shows superior performance with 47.93% profit, 67.16% win rate, and low drawdown. DOI: https://doi.org/10.1007/s10614-025-10988-z
