What I'm looking for

I seek a role building scalable web and AI features with end-to-end ownership, strong engineering culture, and opportunities to improve product impact through automation and performance optimizations.

I am a fullstack developer focused on building scalable, production-ready web applications and AI-driven features that improve user engagement and operational efficiency.

At Revispy I engineered a discussion forum, implemented real-time Server-Sent Events notifications, and led development of a Gen AI content-moderation pipeline that reduced manual reviews by 85%.

I build RAG chatbots, vector search integrations, and AI-driven analytics—shifting heavy evaluation logic to cron jobs and optimizing systems to reduce load times by up to 70% while improving API performance.

I enjoy end-to-end ownership: designing SDKs, containerizing apps, creating CI/CD pipelines, and deploying services, all while emphasizing secure integrations, reliable rollouts, and measurable product impact.
