Expert-Vetted Upwork consultant with over $1,000,000 earned and a 99% success rate. I design and build custom operational systems that eliminate bottlenecks, enforce accountability, and scale with your business.
I am also an L5 Diamond Lovable Partner, the highest ranking available on the platform. I build production-grade applications, dashboards, AI tools, CRM systems, and operational backbones using Lovable when a custom solution is the right answer.
Most businesses do not need “another tool.” They need a system that actually works.
What I Do
I architect and implement custom operational systems across:
• Project Management & Execution Systems
• CRM & Revenue Operations Infrastructure
• AI-Powered Workflows & Internal Tools
• Chatbots & Conversational AI Agents
• Reporting Dashboards & Executive Command Centers
• End-to-End Business Automation
Sometimes that means optimizing monday and mondayCRM, Zoho, Smartsheet, or ClickUp. Other times it means building a custom solution in Lovable with Supabase, APIs, and structured automation.
I focus on building systems that:
• Remove founder bottlenecks
• Eliminate duplicate data entry
• Enforce workflow standards
• Provide real operational visibility
• Scale without becoming fragile
If your business depends on spreadsheets, disconnected SaaS tools, or manual oversight, we fix that.
Custom Systems with Lovable
As an L5 Diamond Lovable Partner, I build:
• Custom CRM and ERP-style platforms
• Production workflow tracking systems
• AI-driven analytics engines
• Lead routing and automation systems
• Admin dashboards and gated portals
• API-connected reporting layers
• Internal operational command centers
These are not prototypes. These are scalable systems designed to replace operational chaos.

Why Clients Hire Me
I do not just “set up software.” I design operating systems.
Clients hire me when:
• Revenue workflows are leaking
• Data cannot be trusted
• Reporting requires manual cleanup
• Founders are stuck in the weeds
• Growth is outpacing infrastructure
Every engagement is structured around measurable operational improvement, not feature implementation.
If you are looking for someone to think strategically, architect clean systems, and build either with enterprise platforms or custom Lovable applications, we should talk.

I am your guarantee of 100%+ completed tasks. I’m expert in Web programming with 30+ years of experience. I always focused on implementing the best engineering practices to optimize and automate processes and increase efficiency. My goal as a programmer — to automate everything as much as possible, implementing intuitive and friendly interfaces and ways of communication between humans and machines. I believe that humans should do only creative work, the routine can be done by programs and robots. I strive to complete everything ever started, not dropping on half way. Autonomous and communicative, always very proactive.

I prefer working with Cloud services (the most experience with AWS and GCP, some with Azure). For CI/CD workflows I prefer Azure DevOps, although I also have experience with GitLab and GitHub+Netlify.
Also, although I’m focusing on software development, I have good design skills, can create user interfaces from scratch and draw vector graphic in Adobe Illustrator, etc. And if you need an old school developer, I do low-level Windows/DOS programming in Assembly language too. And can support and update legacy web-applications written in Perl.
