At THE IT GUY, we craft intelligent, scalable systems that bridge hardware, AI, and
software—powering next-generation products in streaming, IoT, and automation. Our projects
range from AI-driven classification pipelines (Azure AI Foundry, OpenAI, vector search, ML
models) to real-time signaling systems (NestJS, MQTT, WebRTC, RTMP) and SaaS
dashboards with multi-tenant, role-based access control.
If you enjoy building systems end-to-end—from API design and data modeling to integrating
AI models and optimizing inference pipelines—you’ll love working with us.
Key Responsibilities
Backend Architecture & Development
○
Design and implement modular, scalable REST & GraphQL APIs using NestJS /
Node.js / TypeScript.
○
Build and optimize database models using Prisma (PostgreSQL / MongoDB)
with advanced query filtering, pagination, and role-based access.
○
Develop multi-tenant SaaS backend logic (JWT auth, refresh tokens,
permissions, audit logs).
AI & Data Intelligence
Integrate and orchestrate LLMs and SLMs (Azure OpenAI, local models) for
classification, enrichment, and reasoning○
Build agentic pipelines that chain ML classifier outputs with semantic reasoning
and web-based enrichment layers.●
Implement vector search, embeddings, and prompt-flow-based inference
systems using Azure AI Search.
Work on model evaluation, feedback loops, and automated retraining or
fine-tuning triggers.
Systems Integration
Develop and manage MQTT-based messaging systems for device
communication and signaling.
Build WebRTC/RTMP streaming services for video/audio pipelines integrated
with NodeMediaServer, Janus, or Asterisk.
Write automation scripts and microservices to handle real-time workflows and
OTA updates for connected devices.
DevOps & Infra
Deploy services using Docker, PM2, or Jenkins pipelines on DigitalOcean /
AWS / Azure.
Optimize APIs for scalability, security, and performance (rate limiting, caching,
CSP headers, Brotli compression).
Manage secrets, environment configs, and CI/CD pipelines.
