Need a custom application, internal tool, dashboard, automation system, or existing project improved? I build practical web and desktop applications using modern AI-assisted development workflows, with a focus on getting from an idea or technical problem to a working solution quickly. I can help with: • Custom web applications • Windows desktop tools • Internal business software • Dashboards and admin systems • Python and JavaScript applications • React frontends • FastAPI backends • API and webhook integrations • Local AI / Ollama integrations • Automation and data-processing tools • Existing application fixes and new features • Rapid MVPs and prototypes My existing projects include a full MT5 trading platform, automated AI market scanner, self-hosted AI learning library, SNMP wireless alignment software and network automation tools. I use AI to accelerate development, but every solution is personally tested, debugged and reviewed before delivery. How it works
Send me your idea, existing application or problem.
I’ll review the requirements and recommend the simplest practical solution.
We agree on scope, price and delivery.
I build and test the solution.
You receive the working project along with setup/help where required. Small fixes and features are welcome — you don’t need to have a large project.
