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).

My background also includes blockchain & DeFi trading (Ethereum & Solana), on-chain analytics, automation bots, and cybersecurity covering vulnerability assessment, penetration testing (Web, API, Network, Cloud), secure coding, and malware analysis.

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.

Johib was fantastic to work with. He is a great developer with capable front and back end skills. His communication is excellent and am happy with the overall result.

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.

The project was completed on time and of good quality.
