AI-Powered Backend Software Engineer

Harold Camacho is a software engineer passionate about building reliable systems, developing tooling, and AI-powered applications. He enjoys tackling complex problems with clarity and precision, and has hands-on experience across backend development, distributed systems, and modern AI workflows. Most recently, he delivered several core features to Mastra, an open-source TypeScript framework for building AI agents, workflows, and MCP servers — including a PostHog observability exporter, Azure OpenAI integration, improved MCP auth propagation, and multiple developer-experience enhancements. He also co-created Splinter, a serverless ingestion pipeline that transforms unstructured data into embeddings for AI/ML applications. Previously, he contributed to Mozilla Firefox, landing patches in features such as Picture-in-Picture, Reader Mode language detection, Private Browsing UI, and enterprise policy tooling, with work appearing in official Firefox release notes. He also has experience building RAG-based AI chatbots, combining structured and semantic retrieval for accurate, context-aware responses. He is fully open to remote, hybrid, or in-office roles and is eligible to work in Canada without sponsorship.
