🌍🌎🌏Web Document on SQL🌍🌎🌏
I wrote an extensive web document on SQL which resides in GitHub pages, called 🌿Kaye is Learning SQL🌳 This web document covers the following topics, and is aimed at beginners and intermediates in SQL.
💧Database Concepts: A Relational Approach
💧Data Modeling and Normalization
💧Oracle Tables
💧Oracle Integrity Constraints
💧Oracle Queries
💧Multi-Table Joins
💧Aggregate Functions
💧Subqueries
I prepared the Training Database of 🌿Kaye is Learning SQL🌳 myself, taking the European Parliament elections data of 2004-2009.
Although written on Oracle, the SQL commands are easily transferable among other SQL-based databases. For example, I deliver these topics now on Google Cloud BigQuery.
🌍🌎🌏🌍🌎🌏🌍🌍🌎🌏🌎🌏
💎I accumulated hands-on SQL experience over the years, mainly on Oracle tools like Oracle Data Integrator (ODI) - an ETL Tool, Oracle Business Intelligence Enterprise Edition (OBIEE) - a Reporting Tool, Oracle BI Publisher - a Reporting Tool, Oracle Discoverer - a Reporting Tool , Oracle Reports, and Oracle Forms. I have written innumerous ad-hoc reports in SQL for business users.
💎I have hands-on SQL experience on Google Cloud BigQuery.
💎I delivered SQL Trainings to Oracle Customers in several cities in Turkey.
💎I delivered SQL trainings at a university as part of their "evening programs".
💎I delivered SQL trainings "in-house to my colleagues" in my several workplaces.
💎In summary, I have a great many years of hands-on SQL experience, as well as SQL Training and Tutoring experience.

📊Are you spending too much time working with scattered Excel files, manual reports, or dashboards that show numbers but do not support real decisions?
I help finance and operations teams turn complex data into clear, accurate, and decision-ready Power BI dashboards and SQL-based reporting systems.
I am a Financial Manager with over 8 years of experience in accounting and finance. I have worked in different roles—from Payment Accountant to Supervisor Accountant and Financial Manager—giving me a practical understanding of financial processes, reporting challenges, and management needs.
✅ I can help you with:
• Financial and CFO dashboards
• Budget vs. Actual and variance analysis
• Cash flow and working capital reporting
• Inventory, slow-moving stock, and shortage analysis
• Sales and operational KPI dashboards
• Product costing and profitability analysis
• SQL queries, views, and financial data models
• Excel automation and data cleanup
• Power BI data modeling, DAX, and Power Query
🔹 My approach is SQL-first whenever possible. I structure and validate the data before building the visuals, helping ensure that reports remain accurate, scalable, and easy to maintain.
Because I have worked directly inside finance, I understand that a dashboard should do more than look good. It should answer a clear business question, highlight problems, and help managers decide what to do next.
🛠️ Tools: Power BI | SQL Server | DAX | Power Query | Advanced Excel | Python
📩 If you need a reliable financial or operational dashboard that turns your data into useful insights, feel free to send me a message.

Most CRM and automation setups end up half-working: half-migrated, half-automated, draining the team's time instead of saving it. I fix that.
Over 15+ years across CRM architecture, marketing automation, and operations, I've built systems end to end and operated them afterward. I built a six-department operations platform from scratch for a major entertainment and retail group (Zoho Desk + CRM, with AI closing routine tickets over WhatsApp). I led a client-approved migration from GoHighLevel to Zoho One after finding a structural gap that made real accountability impossible on the old platform. And I delivered a full multi-pipeline HubSpot CRM build for an education client, mapping the entire lead-to-alumni lifecycle.
I hold Make(dot)com and n8n certifications, and I use AI daily to build the systems, not just to talk about them.
Tools: n8n, Make(dot)com, Zoho One (CRM, Blueprint, SalesIQ, Voice, Books), HubSpot, GoHighLevel, Claude API, OpenAI API, Oracle Fusion, REST APIs.
If you need a CRM and automation partner who can architect, build, and operate the system end to end, let's talk.
