Summary
🤩
Rockstar🎓
Top SchoolBenyam Ephrem is a versatile technologist and filmmaker based in San Francisco with eight years of experience building production software, developer education products, and indie startups. He founded Back To Back SWE, teaching algorithms and interview skills to millions, and later launched Interview Pen and an AI-powered mock interviewing platform where he architected a custom voice-AI pipeline before mainstream orchestration tools existed. His engineering work spans backend systems, orderbook-ledger APIs, and algorithmic problem-solving—evidenced by contributions to a Java repo focused on data structures and tree algorithms. Benyam pairs creator instincts with hands-on implementation, moving between product design, teaching, and low-level engineering. He has shipped features at Twitter and led small teams through fast iterations, bringing a rare mix of public-facing education impact and practical system-building. Curious and resourceful, he often bridges gaps between researchy voice/LLM experiments and reliable production services.
