KMG

Senior Fullstack Engineer (Java Backend & AI Systems)

KMG • Part-time

Jan 2026 - Present • 7 mos

Own backend reliability and infrastructure for a Kubernetes-based enterprise platform — cut API response time by ~30% and downtime by ~40% while supporting 5k–10k+ daily internal requests. Delivered full stack features end to end for clients and startups: Java (Spring Boot) REST APIs and microservices on the backend, paired with Angular front ends - component architecture, routing, reactive forms, and RxJS — on the frontend. Architected a Retrieval-Augmented Generation (RAG) assistant for enterprise Service Desk: knowledge-base retrieval over Qdrant, automated ticket classification and response-suggestion scenarios, evaluated across multiple LLM backends (Qwen, DeepSeek) for Kazakh/Russian/English support. Planned and executed major platform upgrades and a production OS migration (CentOS 7 → Rocky Linux 9.5, SELinux Enforcing) across 11 servers, closing security gaps without service disruption. Root-cause production incidents end to end, from database configuration to application-level failures, partnering directly with cross-functional stakeholders on technical proposals.
