I’m a Founder-Engineer / Systems-oriented Product Builder.

I design and build end-to-end software systems where:

• business logic is explicit,
• data is auditable,
• infrastructure is treated as part of the product,
• and automation actually replaces manual work.

I focus on backend-heavy platforms, AI-assisted workflows, and infrastructure-aware SaaS — especially in domains where correctness matters (finance, logistics, compliance).

• Event-driven ledgers
• Chart of Accounts & posting rules
• Invoice lifecycle & audit trails
• KSeF-ready and compliance-aware architectures

• LLM-assisted workflows
• n8n-based automation pipelines
• Structured memory & decision logging
• AI agents integrated into real business processes (not demos)

• Route planning & cost calculation
• Driver / operator workflows
• Multi-party coordination systems
• Marketplace-style backend logic

• Self-hosted Linux servers
• API-first backend design
• Systems built to survive bad data, bad users, and partial failure

• C++ (systems, low-level understanding)
• Python (automation, tooling, AI workflows)
• PHP (backend platforms, APIs)
• SQL (data modeling, accounting logic)
• TypeScript / JavaScript (frontend & tooling)

• React
• HTML / CSS
• UI focused on clarity over visual noise

• Linux
• Nginx
• Docker
• MySQL / PostgreSQL
• Cloud & VPS deployments

• n8n
• LLM orchestration
• API-driven agents
• Workflow automation replacing manual operations

• Systems > frameworks
• Auditability over magic
• Explicit data flows beat hidden state
• Infrastructure is part of the application
• Software should fail predictably, not catastrophically
• If it touches money, logs are not optional

• Large-scale TypeScript & React systems
• Advanced backend architecture patterns
• OpenGL & lower-level rendering concepts
• More capable AI agent orchestration
• Scaling multi-tenant SaaS systems
