What I'm looking for

I’m looking for a small, high-ownership team building scalable, secure APIs and AI/LLM systems—where I can take RAG/agents from concept to production, optimize performance, and deliver reliable uptime (remote or relocation welcome).

I’m a Backend Software Engineer with 5+ years building scalable, secure APIs and services, mostly in Python. I focus on performance, data integrity, and production reliability, and I enjoy turning ideas into high-impact products.

In my most recent role as Lead Backend Developer, I designed the full architecture for an AI voice-agent platform for US veterinary clinics. I built LLM function-calling agents over SIP/Twilio with an end-to-end workflow (STT → LLM → function tooling → TTS), and delivered a multi-tenant backend with organization-level isolation and role-based access control.

I also owned the infrastructure, containerization, and CI/CD for a production system processing 600+ after-hours calls per day at 99.9%+ uptime. Alongside core services, I delivered custom per-client agent configurations and CRM (PIMS) integrations, including schema design and data validation for scheduling and patient records.

Earlier, I built an AI-powered book-creation platform with RAG-driven character conversations and integrated custom agents using LangChain/PydanticAI. At Lingvanex, I built a backend platform from scratch to train 200+ lightweight, task-specific language models across a 25+ GPU cluster—designing the training pipeline, queuing for concurrent GPU jobs, and production APIs with NLP and PyTorch.
