Most engineers build what they are told. I build what the business actually needs, and I know the difference between the two. I am Shawaiz, a senior software engineer focused on machine learning systems, data products, algorithmic trading tools, AI-powered applications, and backend platforms. I work with founders, traders, startups, and technical teams who need someone who can understand the real problem, think through the architecture, and deliver a working system end to end. 𝗪𝗛𝗔𝗧 𝗜 𝗪𝗢𝗥𝗞 𝗢𝗡 𝗠𝗔𝗖𝗛𝗜𝗡𝗘 𝗟𝗘𝗔𝗥𝗡𝗜𝗡𝗚, 𝗗𝗔𝗧𝗔 𝗦𝗖𝗜𝗘𝗡𝗖𝗘 𝗔𝗡𝗗 𝗔𝗡𝗔𝗟𝗬𝗧𝗜𝗖𝗦 Python-based model development using TensorFlow, Keras, scikit-learn, pandas, NumPy, and modern ML workflows. I build forecasting systems, predictive models, computer vision workflows, data pipelines, BI dashboards, KPI reporting tools, and decision-support systems designed for real business use, not just notebooks.

𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞 I do not blindly accept requirements and start coding. I first understand the business goal, technical constraints, data flow, user flow, and success criteria. Then I break the work into a clear plan, identify risks early, and deliver clean, maintainable software. Send me the problem you are trying to solve, and I will give you a straight answer on the best technical path forward.

I build AI agents and automation systems that replace manual work — RAG chatbots, AI workflows, and API integrations that ship and run in production. Across 33 jobs and 900+ hours on Upwork I've built a testimonial-automation bot, a RAG chatbot trained on 1,600+ videos, and an AI deal-pipeline for real estate. What I do: • AI agents & RAG chatbots (OpenAI, Claude, LangChain) • Workflow automation (n8n, Make, Zapier) + custom Python • Web scraping & data extraction • API integrations & backend (FastAPI, Django, PostgreSQL) Message me or book a quick call — I'll tell you straight whether I can help and how I'd do it.

🚀 Quant-Focused • Machine Learning Expert • Python & R Specialist • Time Series & Trading Models I’m Younes — a Kaggle Grandmaster, quantitative researcher, and data scientist with 7+ years of experience building predictive models for financial markets, algorithmic trading insights, and high-performance data pipelines. I combine deep statistical knowledge, ML engineering, and market intuition to deliver models that generalize and produce real trading value. 📌 Quant Focus Areas 📈 Financial Forecasting & Alpha Research Short-term & long-term price forecasting Futures & crypto modeling (1-min to daily) Alpha factor research (correlations, volume, volatility, microstructure) Feature pipelines for trading (lags, market microstructure, regime detection) 📐 Machine Learning for Finance Tree models (XGBoost, LightGBM, CatBoost) AutoML (AutoSklearn, AutoGluon, FLAML) Deep learning: LSTM, Transformers (TFT), hybrid encoder-decoder Contrastive learning for time series (SimCLR, VICReg) 📊 Quant Statistics & Econometrics Bayesian inference, regression, probabilistic models Risk modeling, Sharpe optimization, factor modeling Cross-sectional prediction, rank-based metrics (Spearman, IC, IR) 🕸️ Web Scraping & Data Engineering Market data scraping (crypto, options, ETFs, indices) High-volume scraping with proxy rotation Automated pipelines for alpha data collection 🧠 Tools & Stack Python: pandas, NumPy, scikit-learn, statsmodels, PyTorch, TensorFlow Quant/Finance: TA-Lib, vectorbt, backtesting.py, Optuna, featuretools Scraping: Selenium, Scrapy, BeautifulSoup, Async IO pipelines Other: SQL, R (tidyverse), SPSS 💼 Why Work With Me 🔹 Kaggle Grandmaster — top 0.1% of global data scientists 🔹 Strong quant intuition — models designed to avoid leakage and overfitting 🔹 Clear explanations — complex quant ideas made simple 🔹 Reliable execution — clean, reproducible research & code Whether you need a predictive model, backtest, alpha factor, scraping engine, or full quant research, I deliver with precision.

Since 2019, I've connected early-stage startups with senior developers and designers who actually fit their culture and tech stack. No recruitment BS, no flaky freelancers, just people I've worked with and trust. I run New Wave Devs, an engineering studio working with startups across the US, UK, Canada, Netherlands, and Norway. We do team augmentation, MVP builds, design work, and team rescue when things go sideways. Our engineers work directly with your team, usually onboarded in under a week, and you talk to the engineer, not a sales layer. The bench runs deep. On the frontend, React, React Native, TypeScript, and Flutter. On the backend, Ruby on Rails, Node, Python, and .NET. Plus AI engineers shipping RAG and agentic workflows in production, along with designers, DevOps, and QA. Mostly SaaS, marketplaces, fintech, and mobile. These aren't junior generalists. Our people have scaled Postgres past a billion rows, shipped Stripe Connect marketplace payments, built HIPAA-compliant health platforms, run native apps at over a million monthly users, and put RAG assistants in front of real customers. So whether you're shipping a first MVP or hitting your first real scaling wall, someone here has already done it. Why people work with us: fast onboarding (1 to 7 days), engineers who match your culture, transparent pricing, and a track record of 100K+ in contracts with long-term clients who keep coming back.
