With 15+ years of experience in software application development, I have worked with renowned companies such as Avaya, Pramati, CGI, Yash, GMS, Vcentric, Meta-io, CTI Services, and MMTex. My core strengths lie in problem-solving, algorithms, system design, and building high-performance, low-latency systems capable of handling complex, real-time workloads. I specialize in efficient coding, performance optimization, scalable architectures, and event-driven systems, ensuring platforms are robust, secure, and future-ready. Over the past 8+ years, I have led and managed teams, delivering complex trading, fintech, and SaaS platforms with seamless execution. I am an AI/ML expert with deep experience in algorithmic trading, AI-driven signal generation, predictive analytics, reinforcement learning, NLP, and market regime detection. Highly skilled in Python, TensorFlow, PyTorch, Scikit-Learn, with hands-on expertise in backtesting engines, walk-forward optimization, portfolio & risk-based position sizing, and real-time market data processing (WebSockets, FIX, tick-level data, order books).

Python Script for OTM Call Options

He is very competent, fast and reliable. He wrote the program in 2 days and sent it to me immediately. Then when I wanted an additional modification, he wrote it and sent it to me in one day without complaint or additional charge. I will definitely request him if I need another project done.

Zend 1 Developer for Fintech Support Role

From the outset, Johib demonstrated a deep understanding of Zend 1 architecture, quickly familiarising himself with our existing codebase and contributing meaningful improvements in a very short time. Overall, Johib has been a highly valuable asset to the Money Box development team. We look forward to continuing our collaboration with him, and I wouldn’t hesitate to recommend him for any project requiring expert knowledge of PHP and legacy frameworks like Zend 1.
