I am passionate about database design and visualisations in a way that it speaks for themselves. I have been helping companies create data representation, optimization and visualisation solutions by understanding business needs, not only how to make charts.
I realize that data is often complicated, but it doesn't have to look that way if we design it properly from scratch. I combine my experience in data analysis, visualization, and design with the awesome capacities of Power BI to make data understandable and beautiful. My Data Stories are crafted to communicate information in the clearest, most efficient manner. I believe that the more effectively the data is presented, the more easily the information is consumed.
Power BI has fantastic capabilities that allow information to be presented in an appealing, clean style, yet still contain all of its intrinsic depth and complexity. From engineering the data to the finished dashboard, I make the complex approachable.
I am experienced, professional, and I have a passion for what I do. I am pleased to offer complimentary consultations online or by phone. I can also provide you with a sample visualization of your data for a nominal fee.
I look forward to learning about your project and I appreciate this opportunity.
I’m able to:
Build Power BI report using DAX and Power Query
Translate your business problem into compelling storytelling via dashboard
Calculating all your metrics for your business
Connecting all data sources (Database, Azure, AWS, Google Cloud, API, flat files etc) into Power BI and also build custom API connector
Setting up a cloud platform for your BI reports in Azure & AWS (Refer to my other gigs!)

✅ Top Developer at Clutch and Goodfirms
I'm a CTO with 20 years of engineering experience, specializing in Python Full Stack Developer SaaS and Full Stack Developer React architecture. I've learned that most founders don't fail because they can't build, they fail because they build the wrong thing. My job is to make sure that doesn't happen to you.
As an MVP Developer, I focus on SaaS architecture and MVP Development — taking products from idea to live in weeks. My team delivers Full Stack Developer React and Python engineering with AI API Integration built in by default. Behind me is a team of 23 senior engineers with 14 years in SaaS — together we've shipped 84+ products for 70+ clients across 7 countries.
Whether you need AI SaaS Development, a lean SaaS MVP, or full-scale SaaS Business Development — we bring both the speed and the engineering depth to make it production-ready.
🌟OUR ENGINEERING STANDARD
Our standard for MVP Development comes from Gearheart, where we've spent 14 years as a SaaS Developer studio building enterprise products:
- SmartSuite — SaaS Developer and MVP Development from scratch: $1.2M ARR in 4 weeks, $38M raised, trusted by Capital One. Coordinated with up to 4 external teams simultaneously
- Globalli — Python Full Stack Developer SaaS and SaaS Developer project: HR/payroll across 125+ countries, SOC2 Type II, $15M raised. 15+ modules, 21 engineers at peak, 3 years

💡WHY WORK WITH ME

- AI Speed, Engineering Quality: We use Claude Code, Lovable, and Cursor as engineers, not prompt writers. AI Development is 2–4x faster without sacrificing production readiness. Need AI SaaS Development or MVP Development? We do both
- We're Startup Founders Too: As founders ourselves, we know firsthand the challenges you're facing — including where AI Development fits and where it doesn't

I help startups and operations teams turn messy processes, spreadsheets, and disconnected systems into clean internal and external tools inside Retool.
If your team is:
• manually updating spreadsheets
• switching between 5+ tools
• struggling with slow dashboards
• or spending hours on repetitive operational work
I built a Retool app that replaces it.
I’m a Certified Retool Expert with 7+ years of experience building production-grade internal & external tools, admin panels, and data dashboards used daily by real teams, not prototypes.
What I commonly build:
✔ Operations dashboards
✔ CRM & admin panels
✔ Approval workflows
✔ Billing & reporting systems
✔ Inventory and order management tools
✔ Data visualization & analytics dashboards
✔ Automation panels (email, notifications, background jobs)
What you get (this is why clients hire me):
✔ Faster operations (teams usually save 10–30 hrs/week)
✔ One system instead of many tools
✔ Reliable dashboards executives actually trust
✔ Secure user roles & permissions
✔ Clean UI your team can actually use
My Retool Expertise:
✔ Multi-page Retool apps & Modules
✔ Complex queries & transformers
✔ Query performance optimization
✔ User permissions & authentication
✔ Staging → Production deployment
✔ Version control & maintainable architecture
✔ Data & Automation
✔ Retool app embedding into external portal
Data, Backend & Automation
I don’t only build the interface, I design the data flow behind it.
✔SQL (PostgreSQL, MySQL, MariaDB, SQL Server)
✔BigQuery & analytics pipelines
✔ETL & data processing
✔REST & GraphQL APIs
✔Scheduled workflows & background jobs
✔Integrations & APIs I Frequently Connect with Retool

Why Clients Work With Me
I don’t just execute tasks.
I analyze your operations and suggest better workflows before building — many clients end up automating far more than they initially planned.
Clear communication, independent work style, and long-term maintainable solutions are my priorities.
If you’re looking for a Retool specialist who understands both business operations and technical architecture, send me a message and tell me what process you want to improve.
I’ll recommend the best approach, even before you hire me.
