Need to build intelligent, automated data systems or deploy predictive machine learning models? I bridge the gap between raw data engineering, advanced AI, and business intelligence to deliver end-to-end data solutions. With a strong foundation in data analytics and hands-on experience delivering 12+ advanced technical projects, I specialize in building robust ETL pipelines, training deep learning neural networks, and creating high-impact visual dashboards. I don't just analyze data—I build the infrastructure and intelligence that powers it. 🔶 CORE EXPERTISE & COMPLETED WORK: 🔹Data Engineering & ETL Pipelines: Designed and deployed end-to-end automated pipelines that seamlessly extract, transform, and load data, ensuring clean and production-ready data streams. 🔹Machine Learning & Predictive Analytics: Developed 6 complete ML projects focusing on predictive modeling, regression, and classification to uncover complex data patterns. 🔹Deep Learning & Computer Vision: Engineered 4 neural network projects, specializing in advanced data architectures and deep learning models to handle complex, unstructured datasets. 🔹Data Visualization & BI: Built production-grade, interactive dashboards using Power BI, Tableau, and custom Python frameworks (Streamlit/Dash) for real-time insight tracking. 🔶 MY TECHNICAL TOOLKIT: 🔹AI & Machine Learning: TensorFlow/Keras, Scikit-Learn, Neural Networks, Deep Learning 🔹Data Engineering & DevOps: ETL/ELT Pipelines, SQL, Database Management, Docker/Containerization 🔹Languages: Python (Pandas, NumPy, SciPy), R, SQL, Excel VBA 🔹BI & Visualization: Power BI, Tableau, Streamlit, Jupyter Notebooks Whether you need an automated data pipeline, a custom-trained machine learning model, or an interactive dashboard, I deliver scalable, clean, and well-documented solutions.

🚀 AWS & Databricks Certified Data Engineer | AI Automation & n8n Workflows | ETL | Infrastructure I build AI-powered automation and n8n workflows that don’t break under real-world conditions. Most automations fail due to poor data handling and API integration — that’s where I focus. I combine ETL, APIs and infrastructure to create reliable, production-ready systems. With 9+ years of experience across data engineering, database administration, and infrastructure, I design end-to-end systems where data, automation and AI work together seamlessly. 🔹 AI Automation & n8n Workflows (Production-Ready Systems) Most workflows fail at the data layer or between API steps — I design systems that handle these edge cases properly. Designed and implemented n8n automation systems integrating APIs, databases and AI services Built AI-powered workflows for: email automation and personalization support triage and classification data enrichment and decisioning Handled real-world issues like: inconsistent webhook payloads AI output breaking downstream steps retry logic, rate limits and failure handling Focused on building workflows that are: ✔ Stable ✔ Debuggable ✔ Scalable ✔ Easy to maintain 🔹 Data Engineering & ETL Modernization Designed enterprise ETL pipelines using SSIS, Python, PowerShell, Airbyte, dbt, n8n and Dagster Built AWS-based data platforms (Glue, Athena, S3, Lambda, Delta Lake) Databricks Certified Data Engineer with hands-on Spark transformation experience Migrated legacy SQL workflows to modular, cloud-native architectures 🔹 Senior SQL Database Engineering PostgreSQL, SQL Server, Oracle, MySQL Advanced indexing, partitioning, and query plan optimization High-availability architecture and zero-downtime migrations Production performance tuning and database automation 🔹 Infrastructure, APIs & Systems Integration This is where I differentiate. Most automation systems break not because of tools — but because of weak system design. I bring: API integrations across enterprise systems Networking and firewall awareness (Palo Alto, F5) Windows and Linux server administration Identity-aware integrations (Active Directory, secure auth flows) Docker-based deployments Because of this, I build systems that are: ✔ Secure ✔ Network-aware ✔ Scalable ✔ Operationally maintainable 🔹 Enterprise Impact Automated integrations between ERP, LMS, and third-party systems Reduced ~3,000 IT tickets per semester through workflow automation Led BI migrations and built executive dashboards (Power BI, QuickSight) Implemented monitoring, alerting, and governance frameworks 💡 Why Clients Hire Me Most freelancers focus on: automation tools or data pipelines or infrastructure I bring all three together. That means: fewer broken workflows better architecture decisions cleaner integrations stronger performance production-ready systems

Most sellers stop at the browser pixel — which is exactly why your Meta and Google numbers never match what actually hit your bank account. I own the full signal chain: server-side capture, multi-platform attribution, and the data pipeline underneath it, with AI layered on top so the reporting reads itself. I'm the engineer who fixes your tracking AND the analyst who tells you what it means for revenue. Over 5 years I've run the complete tracking-and-analytics stack for companies scaling to 8 figures. WHAT I FIX - Broken or undercounting tracking — conversions firing late, double-counting, or not at all - Numbers that don't reconcile across Meta, Google, GA4, and your backend - iOS/ad-blocker signal loss killing your pixel data - Disconnected data sources with no single source of truth WHAT I BUILD - Server-side tracking: Meta CAPI, server-side GTM, Google enhanced/offline conversions, TikTok, Bing - Attribution: multi-touch models that show which channels actually drive sales, not last-click guesses - Data pipelines: automated ingestion into BigQuery/SQL warehouses — ETL, schema design, data modeling - Custom dashboards: real-time KPI monitoring in Looker Studio or coded React/Next.js - AI automation: natural-language data queries, AI-augmented reporting, n8n + LLM workflows RECENT IMPACT - Engineered tracking infrastructure holding 99.9% data integrity across multi-million-event datasets - Built an AI analytics platform from scratch (Next.js, Python) letting non-technical teams query data in plain English - Owned analytics for 200+ A/B tests that shaped product roadmaps and lifted conversion - Delivered 20+ custom warehouses and dashboards across e-commerce, SaaS, and marketing TOOLS - Server GTM, Meta CAPI, GA4, Google Ads, BigQuery, SQL, PostgreSQL, Python (Pandas/NumPy), React, Next.js, Looker Studio, n8n, dbt HOW I WORK Fixed scope, clear deliverable, stated timeline — no "it depends." Every project ships with documentation and knowledge transfer so your team can run it without me. I'm not here to create dependency; I'm here to solve the problem so well you come back for the next one. HIRE ME IF YOU NEED TO - Recover conversions lost to iOS and ad blockers with server-side tracking - Make your ad platforms and backend finally agree on the same numbers - Build attribution that proves what's working - Turn scattered data into one warehouse and a dashboard people actually use
