Sr. Software Engineer @ CipherSchools

About

I’m a Senior Software Development Engineer focused on building reliable, scalable backend systems and solving complex engineering problems. I work primarily with Node.js, MongoDB, Redis, BullMQ, Docker, and Kubernetes, with experience spanning backend architecture, low-level system design, database optimization, asynchronous processing, and observability. In my current role, I lead the development and delivery of business-critical platforms, collaborating closely with engineering leadership on architecture and technical planning. I’ve designed systems for coding evaluation, asynchronous job processing, automated video transcoding, and production observability. Some of my work has included evolving a certificate processing pipeline from Node.js Worker Threads to BullMQ, increasing throughput from ~50 to 500+ certificates per execution, and building an FFmpeg-based transcoding pipeline that doubled operational efficiency while reducing infrastructure and software costs by approximately 60%. Earlier in my career, I worked across the full stack, building applications with the MERN stack and developing backend infrastructure such as Redis-based caching and rate limiting systems. I’ve also worked as a freelance developer, delivering production applications for startups and small businesses. Beyond individual development, I enjoy taking ownership of systems, mentoring engineers, and turning ambiguous business requirements into practical technical solutions. I’m particularly interested in backend engineering, system design, distributed systems, developer infrastructure, and building products that solve real-world problems. Always open to interesting engineering challenges, meaningful products, and good coffee. ☕
