Chi sono
Hey, I’m Artur, a Full-Stack Product Engineer.
I build web apps end-to-end: frontend, backend, databases, APIs, and product logic.
I’ve worked in production AI startup environments, so I’m used to shipping features, debugging weird issues, improving performance, and making things stable after they break.
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.
If you need someone who can think through both product and code, send me a message.

May 2024 - Present • 2 yrs 5 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.
