I am a senior Data Analytics and BI professional with over a decade of experience helping businesses turn complex data into meaningful insights.

Core Skills: Business Intelligence: Power BI (DAX, Power Query, Dataflows, Semantic Models), Power Apps, Power Automate, Looker Studio, Sisense ETL & Data Integration: MSSQL, MySQL, PostgreSQL, Snowflake, Azure SQL, SSIS, APIs Database Development: SQL Server, Snowflake, Oracle, performance tuning & optimization Automation & Development: C#, ASP.NET, JavaScript, Excel automation What I deliver: ✔ Interactive dashboards & reports ✔ Optimized ETL pipelines & data models ✔ Automated refresh, workflows & API integrations ✔ Reliable, secure, and high-performance data systems Dashboards Delivered: ✔ Sales Whitespace Analysis ✔ Pipeline Trend ✔ Performance Dashboard ✔ Sales Revenue ✔ Bookings to Revenue ✔ Client Profit & Loss ✔ Accounts Receivable ✔ Procurement Activity ✔ Project & Program Report ✔ Succession Planning Dashboard ✔ Customer Information Report ✔ Sales Leaderboard Dashboard ✔ MSEL Dashboard ✔ Prospecting 5500 Dashboard ✔ Employee Salary Forecast I’ve successfully delivered end-to-end analytics solutions from data engineering to visualization for multiple clients, and I’m excited to bring my expertise to new freelance projects. Let’s work together to unlock the true value of your data!

Most data pipelines don't fail loudly. They rot quietly. A job starts silently skipping rows. A dashboard still loads, but the numbers stopped matching reality weeks ago. The warehouse bill creeps up because nobody ever tuned the queries. Eventually someone exports to a spreadsheet "just to be sure" and that's the moment the system stopped being trusted. That's the work I do: build data pipelines and warehouses people actually rely on, and fix the ones that quietly stopped working. Over the last 3 years I've delivered 55+ data projects across finance, healthcare, energy, and e-commerce, from one-off ETL jobs to platforms processing billions of records a day. I work GCP-first (BigQuery, Airflow, dbt, Dataflow), and I'm comfortable across AWS, Postgres, and the messy real-world stack most teams actually have. What I build: - End-to-end ETL/ELT pipelines in Python, SQL, Airflow, and dbt - BigQuery / Snowflake / Redshift warehouses and data models that stay clean as they grow - Migrations off legacy jobs and on-prem databases — without losing data in the move - Metabase, Looker Studio, and Power BI dashboards your team will actually open - Query and cost optimization when your warehouse bill stops making sense - API integrations with proper logging, retries, and checkpoints, so failures are visible instead of silent You probably need me if: - Your pipelines break and you hear it from a stakeholder, not an alert - Reports run slow, cost too much, or quietly disagree with each other - A previous developer left and nobody fully understands the setup anymore - You're scaling fast and the current data stack is starting to crack A few real results: - Architected pipelines processing 5B+ records daily at 99% reliability - Cut a client's warehouse costs ~50% by migrating legacy jobs to BigQuery - 4× throughput and 70% faster ingestion on an API pipeline pulling 2K+ domains a day - 40% faster pipeline runs through Airflow optimization How I work: a clear yes/no on feasibility before you commit, regular updates, and no disappearing mid-project. Most clients come back — usually because fixing one thing surfaces the next. If that sounds like your situation, send a short note on what's breaking or what you're trying to build, and I'll tell you straight what it'll take.

At this point probably you've already read dozens of AI-generated or copy-pasted "100% Job success, Top Rated 👑" profiles overviews of other freelancers and I bet you don't want to read another one. To make it short - I'm proficient at AWS as Solutions Architect and DevOps, worked with all the main services, including AI/ML (such as Bedrock, Rekognition, Textract, etc.); also I have a big experience with PHP backends and Python. Key points: * Doing things in a proper way is my priority. E.g. I will never create static AWS IAM key for an app running on EC2 instance, even if your dev team insists on that (probably simply because they don't have enough expertise) - the proper way to do that is to leverage IAM roles, because this is much more secure. I already had several customers suffering from conflicts with their dev teams where dev teams simply destroyed their setup, because they had static IAM keys, while with IAM roles that would be impossible * I always support my customers after the contract is ended. I cannot do 24/7 support, but believe me, in case of any issue, I'll respond as soon as possible * If you hire me for resolving some bug/issue and it's not resolved by me - I won't charge you. Please note, that this applies to initially described bug/issue; in a situation when there is a next bug appears after the first one is fixed - I'll let you know if I can solve it or no and what will be an additional cost (typical example - after the fix of SSL issue it turns out that site is not working due to some mistakes in code - this is different issue, not related in any way to the first one) * I'm not a good fit for any job that requires 24/7 support even with rotation - even though I'm responding as fast as I can - I cannot always guarantee that * I can work via screenshare, but that's not as efficient as direct access, and therefore will be more expensive as more time will be spent Thanks for reading this and looking forward to our collaboration.
