Most businesses collect a huge amount of data, but much of it goes unused. I help turn raw data into clear insights, interactive dashboards, and automated reporting systems that drive real decisions. With 7+ years of experience in data analysis, dashboard design, and reporting automation, I specialize in Power BI, Tableau, Looker Studio, Excel, SQL, and Python—making it easier to track sales performance, customer behavior, marketing campaigns, and operational efficiency. If your dashboards feel confusing, your reports take too much manual work, or you’re not getting real insights from your numbers, I can help. My focus is on simplifying complexity, automating workflows, and connecting data directly to business goals. The result: less time spent on spreadsheets, more time making confident, data-driven decisions.

With over 10 years of expertise in C# .NET development, I specialize in building enterprise-grade applications using ASP.NET Core, ASP.NET MVC, Web API, and Entity Framework. My extensive experience includes Azure Cloud Services, SQL Server optimization, microservices architecture, RESTful APIs, and SignalR real-time applications. I'm proficient in clean architecture patterns (SOLID, DDD), full-stack development with React/Angular, and delivering scalable, production-ready solutions with comprehensive testing and CI/CD pipelines. ===================================================================== For the past 4 years, I've expanded into Python AI/ML development, creating intelligent solutions with TensorFlow, PyTorch, Scikit-learn, and Keras. I build custom machine learning models, NLP applications, computer vision systems, and predictive analytics. My recent focus includes LLM integration, OpenAI API implementations, RAG systems, AI chatbots, and deploying ML models using Flask, FastAPI, and Docker. I bridge traditional software engineering with cutting-edge AI to deliver transformative business solutions.

I am a Snowflake Data Engineer specializing in building cloud data warehouses and automated data pipelines. I design end-to-end solutions including raw data ingestion, transformation, and analytics modeling. I have experience implementing Medallion Architecture (Bronze, Silver, Gold layers), star schema modeling, and SCD Type-2 historical tracking using MERGE statements in Snowflake. My technical stack: Snowflake • SQL • Data Modeling • Streams & Tasks • ETL/ELT Pipelines • Python • Streamlit Dashboards I can help with: – Snowflake assignments and debugging – SQL query writing and optimization – Data warehouse schema design – Automated data pipelines – Analytics dashboards I focus on clear communication and quick turnaround. I also explain the solution so you understand the system, not just receive the code.

I've managed all aspects of technology which helps me get up to speed quickly on projects. I'm frequently called in on existing projects and have to figure out what's what. (Most documentation is non-existent or lousy.) I help non-technical product owners and stakeholders make technical decisions about their applications and "translate" for their developer(s). I'm a business owner and spent many years implementing accounting software, so I'm comfortable with the "business side" of applications (electronic payments, SEO, marketing, etc.) I currently manage several SAAS applications hosted in Azure and AWS. I specialize in DevOps, Cloud hosting and Authentication/Authorization (OIDC/OAuth/SSO). I've been working in software development for over 30 years, primarily with Microsoft tools (C#, SQL Server, ASP.Net, SQL Server, Entity Framework, etc.). Over the last decade, I've also work with Angular (a lot), React, PHP and Python. I have published mobile apps for both Android and iOS.

I help companies build reliable data pipelines, modernize reporting, and turn messy source data into clean, usable datasets for analytics and decision-making. My core strengths are Data Engineering, ETL/ELT, Databricks, SQL, Azure, and Power BI. I work across the full flow from ingestion and transformation to semantic modeling, dashboard-ready datasets, and data quality checks. I can help with: - Building batch or incremental ETL/ELT pipelines - Databricks and PySpark data transformation - SQL performance tuning and data modeling - Azure Data Factory / Synapse-based orchestration - Power BI semantic models, reporting datasets, and KPI layers - Data validation, reconciliation, and pipeline reliability improvements - Migrating legacy SQL/SSIS workflows into more maintainable modern data platforms Recent project experience includes work across multi-source analytics platforms, Bronze/Silver/Gold data layers, fact/dimension modeling, validation frameworks, and business-facing reporting for operations and performance use cases. I focus on solutions that are practical, maintainable, and easy for teams to operate after handover. Tools I commonly work with: Databricks, PySpark, SQL, Azure Data Factory, Azure Synapse, Power BI, SQL Server, SSIS, Delta/Parquet, and dimensional modeling. If you need someone who can both build the pipeline and think through data quality, reporting readiness, and downstream business use, I’d be glad to help.

Analytics Engineer | BigQuery, dbt, Looker Studio — from ad platforms to CRM to internal tools With 3 years of experience as a Business Analyst and Tool Enablement Specialist — including work at TELUS International — I sit at the intersection of two things most freelancers only do one of: building internal tools that teams actually use, and modelling data that leadership can actually trust. Clients come to me when they have one of these problems: — Their team is running on disconnected spreadsheets and manual handoffs — Their ads and CRM data exists but no one can read it clearly — They need a real internal system, not another workaround 🔹 What I build: 1. AppSheet Applications (my core specialty) Task management and operations tools Inventory and IT request tracking systems CRM and workflow apps for non-technical teams Data ingestion pipelines from Google Drive into BigQuery Result: your team works in one structured system they actually adopt 2. Data & Reporting (BigQuery · dbt · Looker Studio) Connect Meta Ads, Google Ads, and CRM data into one place Clean and model your data using dbt and BigQuery Build Looker Studio dashboards with correct metrics — ROAS, CTR, CPC at every level Result: numbers you can act on, not just look at 🔹 Real examples of what I've delivered: ✔️ Built an IT inventory and request tracking app used across departments ✔️ Modelled Pipedrive CRM + Meta Ads data into a unified performance dashboard ✔️ Created a task management system replacing a tangle of spreadsheets ✔️ Built calendar and operations tools connected to BigQuery as the backend 🔹 Tools I work with: AppSheet · BigQuery · dbt · SQL · Looker Studio · Pipedrive · Meta Ads · Google Ads · Google Sheets · Google Drive I combine a deep understanding of how teams actually work with the technical skills to build systems around that. Every solution I deliver is something your team can run independently — not something that breaks the moment I leave. If you want cleaner operations, clearer data, or both — let's talk.

I build production-grade data systems — increasingly with AI integrated directly into the pipeline — that keep running long after I hand them over. WHAT I HAVE DELIVERED IN PRODUCTION: → Quantitative backtesting engine — 817 trading days across AMZN, GOOGL, MSFT, ORCL. HAC/Newey-West corrected, FDR-adjusted for multiple comparisons. Strongest single result: ORCL's cheap EV/Revenue bucket showing a +78% median 60-day return — a thin-sample, high-conviction directional signal, not a guaranteed number, and I'll always tell you which is which. → Automated macro pipeline — 20+ FRED series, zero manual refresh, live Looker Studio dashboards, LLM-assisted summarization layer. Client engagement grew 30 → 40 hours/week after the first delivery. → National ML infrastructure — 85% accuracy ensemble (AUC-ROC 0.89) deployed across 47 regions for a leading international development partner. 160+ professionals trained on the system. → Weekly financial pipeline — 280,930 rows across 66 tech companies, 8-tab automated Excel workbook. Zero manual steps, zero code changes to onboard a new company. → VBA/Excel financial automation — 14 business units, 1,000+ employees, 3 budget scenarios. Full refresh under 60 seconds, zero formula errors. → Candlestick analytics system — ES futures research tool, 40+ automated metrics per row, rule-based pattern detection across 3,000+ rows. MY SWEET SPOT: Quantitative finance and trading research tools AI-augmented pipelines — LLM/RAG integrated into ETL for summarization, extraction, and automated reporting Financial data pipelines and live market data systems SaaS data layers — dbt, Airflow, multi-source ingestion Government and research-grade analytics infrastructure WHAT SEPARATES MY WORK: Config-driven by design — a client updates a column, the output changes automatically. No developer needed after handover. QA built in, not bolted on — every system validates itself on every run. Fixed-price projects preferred — you know the cost upfront, I absorb the risk. Honest about limits — if a result is directional rather than proven, I say so before you find out the hard way. Systems that outlive the engagement — documented, reproducible, running the same way months after I hand them over. WHAT I BUILD: Python · SQL · R · VBA · dbt · Airflow · AI Integration · LLM/RAG · XGBoost · TensorFlow · PyTorch · NLP (BERT) · MLOps · ETL/ELT · Backtesting · HAC/NW · Power BI · Looker Studio · Tableau · BigQuery · Snowflake · PostgreSQL · AWS · GCP · Azure · Docker · Terraform If you have a pipeline that's breaking, a signal that needs adversarial validation, or a research tool that needs to go from prototype to production — send me a message with what you're working with. I'll tell you honestly whether it's a fit.
