I’m a hybrid application support and full-stack SaaS engineer with nearly 6 years of experience in B2B and IT environments, including 2 years at an international SaaS vendor where I handled L2/L3 incident management and worked closely with client and development teams to reproduce, qualify, and resolve production issues. I enjoy bridging the gap between real-world support needs and engineering solutions—turning incident learnings into clearer runbooks, better escalation paths, and safer releases. Since late 2025, I’ve been independently designing and building full-stack multi-tenant SaaS products using TypeScript, Next.js, PostgreSQL, and Supabase, including Stripe subscription flows, automated API/E2E testing, and practical GenAI integration (structured prompts and reusable workflows with human validation). I’m also a strong quality-and-verification mindset engineer—using monitoring, staging validation, and post-deployment checklists to ensure reliability while collaborating with customers in a forward-deployed, consultant-style way.…I’m a hybrid application support and full-stack SaaS engineer with nearly 6 years of experience in B2B and IT environments, including 2 years at an international SaaS vendor where I handled L2/L3 incident management and worked closely with client and development teams to reproduce, qualify, and resolve production issues.
