Renaldy Prasetio

I’m a Full Stack Software Engineer (AI / LLM Systems) with 4+ years of experience building scalable full-stack applications and deploying AI-powered systems in production. I bring strong hands-on ability across Python (Django), React (TypeScript), and cloud infrastructure (AWS).

At Penetwork Pty Ltd, I designed and deployed LLM-powered workflows and AI automation pipelines that integrate AI into CRM and analytics platforms. I built transcription and structured output pipelines (real-time + async), implemented event-driven architecture with Redis and Celery, and improved system performance by ~20% through backend optimization and SQL tuning.

I also focus on reliability and deployment: I deployed and maintained systems on AWS (EC2, S3) with Docker-based infrastructure. I work comfortably with stakeholders to prototype quickly and ship reliable solutions, and I provided customer-facing technical support to troubleshoot issues and deliver effective outcomes.

Through projects like TxCo and LeadCron, I’ve built end-to-end AI systems—LLM workflows, RAG-style pipelines, and agentic automation—using React + Django, n8n, and function-calling patterns to connect LLM outputs directly to backend systems. I’m motivated by turning AI capabilities into practical customer products with strong validation, evaluation, and secure handling of sensitive data.
