One person,
full accountability.
We don't believe in the "sales-to-implementation" handoff game. The person who designs your solution is the same person who builds it. No handoffs. No translation loss. Just results.
Two minds, one mission
Why Charles & Eric?
Landslide Logic was born from a simple observation: businesses can't fix what they can't measure, and they can't measure what they can't see.
We cover the entire spectrum of modern business operations:
Charles builds the engine
He creates the custom apps, automations, and integrations that make your operations run smoother and capture data at the source.
Eric builds the dashboard
He takes that data, cleans it, applies financial rigor, and turns it into the "Answers" you use to steer the company.
Midwest Pragmatism: We are based in the Cincinnati, OH area. We prefer shaking hands to sending emails, and we measure success in hours saved and revenue recovered, not in "digital transformation synergies."
Core Values
The principles that guide every project we take on.
One Person, Full Accountability
We don't believe in the "sales-to-implementation" handoff game. The person who designs your solution is the same person who builds it. This isn't just about efficiency; it's about accountability. You have one throat to choke (though we prefer "one hand to shake").
Where Business Meets Technical
We are equally fluent in boardroom strategy and Python scripts. We understand why you need the report (for the bank, for the board, for cash flow) AND how to pull that data out of your legacy ERP technically. That's rare, and it's our superpower.
Modern Velocity
We leverage modern AI coding tools to move fast, but we don't break things. "Agile" shouldn't mean "making it up as we go." We use AI-assisted development to build robust, fully tested systems in the time it takes traditional firms just to write the specs.
Real Solutions, Not Buzzwords
We're allergic to people throwing around terms they don't understand. When we talk about AI enablement, we mean building actual systems (like MCP servers) that let AI assistants work with your data. Not just saying "AI" to sound innovative.
Meet the Team
Charles Squeri
Co-Founder | Systems Architect & Product Builder
The Vibe: The product builder who bridges the gap between strategy and execution
Core Focus: Systems Integration, Workflow Automation & AI
Charles is a product builder who bridges the gap between boardroom strategy and technical execution. A former Product Manager for Fortune 500 fintechs (Worldpay, Circle), he left the corporate world to prove that one person—armed with modern AI tools—can build enterprise-grade systems faster than a traditional agency. He doesn't just design the solution; he writes the code, deploys the database, and hands you the keys.
Key Differentiators
- One Person, Full Accountability: No handoffs. The person you tell your problem to is the same person writing the Python script to fix it.
- AI-Native Speed: Built and launched 3 production-ready applications across different industries in under a year (2024-2025).
- Full-Stack Fluency: Equally comfortable designing a React Native mobile interface as he is architecting a Postgres database.
Notable Work
Complex Workflow Automation (CMAIS)
Built a custom AI-powered portal for a residential construction firm. The system handles customer selections, auto-generates RFQs, and includes a natural-language chat bot for field teams. Result: Saved hours of admin work weekly.
Consumer Mobile Apps (RTB)
Designed and coded a social coffee tracking app with AI photo recognition, launching it to the iOS App Store in just 2 months.
Developer Platforms (Circle)
Led the strategy and launch of a developer console serving 10,000+ users, bridging the gap between complex Web3 infrastructure and usability.
Eric Deuber, CPA
Co-Founder | Data Strategist & Analytics Engineer
The Vibe: The Analyst who finds the money you didn't know you were losing
Core Focus: Business Intelligence & Data Strategy
Eric is a data strategist who speaks the language of finance. With a unique background as both a CPA and a Data Engineer, he builds the pipelines that turn messy operational data into impeccable financial 'Answers.' He has modernized data stacks for private equity-backed firms and international banks, ensuring that when leadership looks at a dashboard, the numbers actually match the bank account.
Key Differentiators
- The CPA Advantage: Unlike most data developers, Eric understands GAAP, accruals, and P&L statements. He builds data models that accountants trust.
- Full-Cycle Analytics: He handles the entire chain—extracting the raw data, cleaning it in the warehouse, and visualizing it for the boardroom.
- Financial Rigor: Specialized in revenue reconciliation and financial forecasting models that drive M&A decisions and budget planning.
Notable Work
Revenue Reconciliation Engine
Replaced a legacy manual process with an automated Snowflake pipeline for a major pet care company, reconciling cash-based transactions with monthly GAAP financials.
The 'Source of Truth' P&L
Built a centralized Profit & Loss system in Power BI that consolidated metrics from customers, appointments, and revenue into a single view used by executive leadership.
Predictive Modeling
Developed Python models to predict center visits and staffing needs, directly impacting labor budget efficiency.
