Project history
Designed and built an AI-powered nightly regression triage system (Claude, custom agent skills, MCP servers, bug-tracker and repository integrations, web UI, chat bot and automated daily reports), cutting manual triage effort by ~50%. Coordinated a team of 4 engineers handling daily nightly regression triage. Scrum Master for a team of 10: sprint planning, refinement, stand-ups, reviews and retrospectives; administered Jira workflows, boards, dashboards and automation. Evaluated AI-generated analysis for accuracy and continuously refined prompts and skills. Tested features through real-time traffic analysis; deployed E2E environments on VMware vSphere. Configured and validated firewalls, routers, switches and endpoints. Manual and automated testing with a custom internal Python framework. Built CI/CD and automation pipelines with Jenkins, Groovy, Bash, APIs, GitHub and Bitbucket.
Built an AI agent system that automatically analyzes nightly regression failures and reports the results to the team, cutting manual triage effort by ~50%. Technologies: Claude, LLM agents, MCP servers, Custom skills, Python.
Multi-tenant appointment booking platform for barbershops and beauty salons, built end to end with AI-assisted development (Claude Code): requirements, user flows, architecture, development, testing and deployment. Includes online booking, staff management and automated WhatsApp notifications. Technologies: Next.js, React, TypeScript, ASP.NET Core, EF Core, Hangfire, PostgreSQL, WhatsApp Cloud API, Azure Blob, Railway.
