My main stack is TypeScript, React, Next.js, Node.js, Python, and PostgreSQL. I can build an MVP from scratch, clean up an existing app, or turn a rough product idea into something usable.

May 2024 - Present • 2 yrs 2 mos

PresentSimple AI - AI agent for creating presentations - Led daily standups and cross-functional execution across product, design, and engineering, turning ambiguous requirements into scoped work and shipped features. - Built a Python Figma-to-layout ingestion pipeline using the Figma API, Telegram, and PostgreSQL, processing a 45-slide template and ~3,950 records in one run. - Replaced N+1-style database writes and deletes with batched bulk operations and transactional retry handling, making layout sync reliable at higher data volume. - Built AI-assisted content generation with quotas and moderation checks, speeding creation while keeping abuse, cost, and output quality under control. - Connected CloudPayments subscriptions to feature-flagged access, helping the team roll out and A/B test paid features without hardcoded gates. - Moved long-running asset generation into queue-backed jobs with retryable failures, keeping heavy work off user-facing request paths. - Built one-tap OAuth and RBAC authentication, reducing onboarding friction without weakening access control. - Built release-safety tooling around typed env validation, CI checks, Docker deploys, and observability, reducing config drift and regressions. - Stabilized interactive editor flows with optimistic updates, cache invalidation, and cleaner local/server state boundaries. - Automated lifecycle messaging and reminders, clarifying billing states while reducing support overhead.
