I help businesses build practical AI automation systems that reduce manual work, improve follow-ups, and centralize operations across mondaycom, email, WhatsApp, CRMs, forms, documents, and internal workflows. My core work is designing and implementing AI-powered operating systems using tools like mondaycom, OpenClaw, automation platforms, APIs, and custom AI agents. This includes: • AI assistants for internal operations • OpenClaw-based agent systems for business workflows • mondaycom CRM setup, dashboards, automations, and integrations • Email and WhatsApp workflow automation • Lead intake, follow-up, sales pipeline, and client onboarding systems • Task routing, reporting, reminders, and manager dashboards • AI support for documents, client communication, and operational handoffs I focus on systems that are useful in the real world, not just impressive demos. The goal is simple: less manual chasing, clearer visibility, faster response times, and better control over your business process. If you already use monday com, Google Workspace, WhatsApp, forms, spreadsheets, or multiple disconnected tools, I can help turn that into one structured automation system with AI support where it actually makes sense. My approach is practical: 1. Understand the workflow 2. Map the bottlenecks 3. Design the automation structure 4. Build and test the system 5. Train the team 6. Improve it based on real usage I can help with one-time builds, system upgrades, automation repairs, AI agent setup, and long-term operations support.

With over 23,000 hours worked, $800,000+ earned, and a 100% Job Success score on Upwork, I've helped startups, founders, and established businesses turn ideas into successful software. Whether you're validating a startup idea, building an MVP, launching a SaaS platform, automating business processes, or developing a custom ERP system, I have the experience to take your project from concept to production. I don't just build applications, I help clients make the right technical decisions from the start, reducing risk and avoiding expensive rebuilds later. What I Build • SaaS Platforms • MVPs & Startup Products • ERP & CRM Systems • Internal Business Software • AI-Powered Applications • Dashboards & Reporting • Workflow Automation • Client & Employee Portals • Marketplaces • Booking Platforms • Inventory Systems • Custom Web Applications Technical Expertise Bubble(.)io is my primary development platform, allowing me to deliver applications much faster than traditional development while maintaining enterprise-quality standards.

Why Clients Hire Me Before founding DarkMS, I spent more than a decade managing software projects, budgets, timelines, and technical teams. That experience allows me to contribute well beyond development. Every application is designed to be: • Secure • Scalable • Easy to maintain • Fast and responsive • Built around your business processes Experience I've delivered software for clients in: • Manufacturing • Financial Services • Healthcare • Construction • Education • Logistics • Property • Professional Services Projects include: • Enterprise ERP systems • AI-powered education platforms • Financial services applications • Fuel card management platforms • Compliance systems • Quoting & estimating platforms • Customer portals • Inventory management solutions • Workflow automation My Approach Every successful project starts with understanding the problem, not just the feature list. I'll help validate your idea, recommend the right architecture, identify potential risks, and build software that can grow alongside your business. Many of my clients begin with an MVP built in Bubble to validate their idea quickly. As their products mature, I also help integrate technologies such as Node.js, Supabase, PostgreSQL, and custom APIs to support increased scale and performance. Whether you're a founder with a new idea or an established business modernising operations, my goal is the same: build software that delivers real business value. If you're looking for an experienced developer who combines technical expertise with commercial thinking and clear communication, I'd love to discuss your project.
