Abhiuday Gupta | Systems & Backend Architect ⚡

Profile Banner

Architecting high-performance backend systems, optimizing complex databases (SQL/NoSQL/Aerospike), and building universal developer tooling. Passionate about open-source innovation, clean concurrency, and scalable engineering.


⚡ Core Architectural Philosophy

  • 🚀 High-Performance Backend Systems: Specializing in low-latency microservices, concurrent execution models in Go & C++, and efficient memory management. Re-architected request handling at Zeta using a Command Pattern execution model, reducing EOD batch processing time by 60% (from 4 hours to 1.5 hours).
  • 🔍 Advanced Database Engineering: Deep expertise in relational (PostgreSQL, MySQL, OracleDB) and NoSQL (MongoDB, Redis, Aerospike) optimization, dynamic indexing, and complex schema querying.
  • 🤖 AI & LLM Systems: Architecting privacy-first AI workflows using local LLMs (Ollama) and speech-to-text models (OpenAI Whisper) to ensure zero data leakage in sensitive domains.
  • 🛠️ Universal Developer Tooling & GitOps: Passionate about reducing developer friction through cross-platform SDK management, automated dependency resolution, AWS Lambda serverless execution, and Kubernetes reconciliation loops.
