Alexander L.
ERP Architect | Systems & Full-Stack Developer | AI & Integrations
🎯 ERP, Systems & AI Solutions That Work I help businesses modernize legacy systems, build reliable ERP and business applications, and connect data, APIs, and existing platforms into scalable workflows. With 20+ years of IT experience across systems architecture, software development, ERP, BI, integrations, and Service Desk operations, I bridge the gap between business needs and technical execution. 💼 What I Do ERP & Business Systems • ERP implementation, architecture & configuration • Business process analysis & system design • Legacy system modernization • Requirements gathering & documentation • Troubleshooting & systems investigation Custom ERP & Systems Integration • ERP-like ecosystems using existing business applications • REST API & third-party system integrations • Data Warehouse-driven business systems • Connecting disconnected platforms into cohesive workflows • Custom internal business applications Full-Stack Development • PHP, JavaScript, Python, HTML/CSS • MySQL & T-SQL • REST API development • Full-stack development & technical leadership Data, BI & Automation • Business intelligence & reporting • ETL & data integration • Data Warehouse architecture • SQL development & data analysis • Workflow automation Service Desk & IT Operations • Service Desk setup & leadership • Tier 1/Tier 2 support & escalation • Incident triage and resolution • Backlog and escalation management • Post-launch support & ITIL-based processes AI & Modern Technology • LLM integration • RAG & Agentic AI • AI-ready business systems • Generative AI implementation • AI integration with existing business platforms 🧠 My Approach I don't look at technology in isolation. I first understand the business process and the problem you're trying to solve, then determine the right architecture, integrations, and development approach. For legacy environments, that may mean modernizing what's already working rather than replacing everything. In some cases, I can connect existing business applications through APIs and a centralized Data Warehouse to create a practical ERP-like ecosystem, without the cost and disruption of replacing everything with a new ERP. For new projects, I can design and deliver scalable business systems from the ground up. For AI initiatives, I focus on integrating AI where it creates genuine value within your existing data, systems, and workflows. 🤝 Who I Work With I work best with businesses that need a technical partner who can think beyond individual development tasks, from ERP and systems integration to legacy modernization, BI, Service Desk operations, and AI. If you have a system that needs to be improved, a business process that needs to be streamlined, or a technology challenge that needs an experienced technical owner, let's talk.
