Do you have an AI vision that needs to become a real, working product? I don't just build models; I engineer complete, scalable solutions that turn data into actionable insights and automation. For over five years, I've specialized in bridging the gap between cutting-edge Artificial Intelligence (AI) research and robust software that delivers real-world value. My core expertise lies in computer vision and machine learning, but my skill set is full-stack. This means I can own your project from the initial data pipeline, through model training and optimization, all the way to deploying a polished desktop application or a secure enterprise API. I thrive on building tools that work seamlessly for end-users, whether it's a retail manager, a traffic controller, or a sports coach. My strongest suit is developing intelligent systems that "see" and understand the world. I've built a retail analytics platform (CrowdIQ) that transforms standard CCTV into a source of business intelligence, tracking customer demographics and behavior. In the sports domain, I created PadelIQ, an analytics engine that uses computer vision to track player movement, posture, and court coverage from match footage, providing real-time coaching feedback. For public safety, I developed a traffic management system (OmniRoad AI) using advanced object detection for real-time accident and congestion monitoring. Beyond computer vision, I architect full-scale data science pipelines. A prime example is my telecom churn prediction project, where I built a machine learning model to identify at-risk customers and paired it with an interactive Power BI dashboard. This end-to-end approach—from data analysis to a clear visualization of insights—ensures the model's findings directly inform business strategy and retention actions. I also develop the tools and infrastructure that power AI applications. I've built secure, enterprise-grade systems like DevelmoGPT, a RAG-based LLM that allows for secure, semantic search over private company documents. From creating simple utilities like PDF-to-audio converters to designing complex role-based access systems, I ensure the foundation of any AI solution is reliable, secure, and maintainable. My process is collaborative and results-driven. I start by deeply understanding your business problem, not just the technical requirement. We'll then iterate through prototyping, development, and testing to ensure the final product not only meets specs but also delivers tangible ROI. I communicate clearly at every stage, providing demos and documentation so you're never in the dark. Let's connect. Share your project idea or challenge, and I'll provide a clear outline of how we can leverage AI, machine learning, or computer vision to build your intelligent solution.

Having 9 years++ in IT-related development, I currently specialize and focus on PineScript for creating Strategy Tester and Indicators on the TradingView platform. I have worked with many Professional/Prop/Funded Traders, Paid Indicator Providers, Fund Managers, and some Hedge Funds; already created and/or modified 500++ Indicators and strategy testers based on other indicators (MACD, Stoch, RSI, SSL Channel, MA, All Candlestick Pattern, CCI, etc.), various candle types (Normal Candle, HeikinAshi, Renko, LineBreak, etc), or based on the new logic (create from scratch). Other features that I ever worked for: - Take Profit/Stop Loss/Break Even/Trailing SL/Trailing TP implementation - Multiple TimeFrame (MTF)/Higher TimeFrame (HTF)/Lower TimeFrame (LTF) based indicator - Custom plottings & alerts - Informative table addition - Market structure automation - Pattern recognition automation - Multiple trade and pyramiding implementation - Repainting handle - Risk sizing for strategy tester - Multiple-state trading algorithm implementation - Rule-based system strategy implementation - Alert Integration with 3rd party Let me know if you're interested in discussing something with me.

I specialize in turning messy, real-world time series data into reliable forecasts that your operations team can actually act on. Whether you need demand planning for a retail supply chain, inventory forecasting for an e-commerce SKU catalog, or demand sensing for a CPG manufacturer reacting to short-cycle signals — I build end-to-end pipelines that hold up in production, not just in a notebook. Most clients come to me after a failed model: one that was accurate in hindsight but fell apart during the holiday spike, the product launch, or the market anomaly. I design for those edge cases. What I specialize in: Time Series Forecasting (LSTM for time series, Prophet model tuning, ARIMA, Exponential Smoothing, Ensemble methods) · Demand Sensing & Demand Planning · Inventory Forecasting & SKU-level optimization · Churn Prediction (classification models: XGBoost, SVM, Logistic) · Anomaly Detection for IoT and financial streams · EDA, Data Cleaning, and Pipeline Engineering · Dashboards in Plotly Dash and Streamlit Tools & stack: Python (Pandas, NumPy, Scikit-learn, TensorFlow/Keras, statsmodels) · SQL · Jupyter · Google Colab · Excel My process (what makes working with me different): I start every engagement by auditing your data before writing a single line of model code. Forecast accuracy KPI degradation is almost always a data quality problem in disguise — irregular timestamps, leakage, or misaligned seasonality. Catching this early saves you weeks. I deliver interpretable outputs — not black-box weights — with documented assumptions so your team can maintain and retrain without me. Every model comes with an error analysis, confidence intervals, and a plain-English summary of what drives the forecast.
