AI / Full-Stack Engineer: AI Infrastructure & Agentic Systems

Hyderabad, Indiarohittcodes@gmail.comrohitt.codeslinkedin.com/in/rohittcodesgithub.com/rohittcodes

SUMMARY

AI / full-stack engineer who builds production AI systems, from RAG pipelines to workflow-orchestration engines, designed to hold up under real traffic and multi-tenant load. Works across backend architecture, agent infrastructure, and full-stack delivery with TypeScript, Python, NestJS, FastAPI, PostgreSQL/pgvector, and Docker.

EXPERIENCE

Full Stack Developer, createxpSep 2025 - Present

Built and deployed a production RAG pipeline combining LLM-based intent extraction, vector retrieval, and contextual ranking, delivering streaming AI responses in under 200ms
Designed a multi-signal ranking service (vector similarity, specification matching, contextual scoring) and shipped it as a Dockerized backend with authentication, webhooks, and structured logging
Redesigned the underlying PostgreSQL specification data model and built automated migration tooling, safely migrating 10,000+ records with no manual cleanup

Software Development Engineer Intern, Grit LabsJul 2025 - Sep 2025

Built fam.cool, an internal testbed for prototyping AI personas, using prompt-based conditioning and behavioral tuning to differentiate agent personalities, with real-time messaging via Express.js, PostgreSQL, RabbitMQ, and WebSockets
Built full-stack systems for jumble[cash], an AI-assisted on-chain arcade used by 1K+ users, implementing complex client state, multi-round game flows, and integration with an AI decision engine
Owned deployment infrastructure across both products (Docker, Kubernetes, DigitalOcean), enabling the two-person team to ship independently to production

Full Stack Developer, createxpMay 2025 - Jul 2025

Migrated an application from a tightly-coupled tRPC architecture to a dedicated Express.js backend and Next.js frontend, decoupling client and server concerns and simplifying state management with React Query
Built a hierarchical file-management system on Amazon S3, replacing ad hoc file handling with structured nested directories, uploads, and public/private access controls

PROJECTS

Linea: Open-Source AI Workflow Orchestration PlatformTypeScript, NestJS, LangGraph.js, BullMQ, PostgreSQL/pgvector

getlinea.app

Architected and open-sourced a production-grade AI workflow orchestration platform built around LangGraph, BullMQ, NestJS, and PostgreSQL/pgvector, with a published TypeScript SDK
Supports composing agents, RAG, tool calls, and human approvals into durable, multi-tenant workflows, including subworkflows and checkpointed execution with retries and token accounting
Designed a provider-agnostic AI abstraction spanning Anthropic, OpenAI, Google, Groq, xAI, and Ollama, with workspace-level bring-your-own-key resolution

3DLabs: Autonomous AI Video PipelineNext.js, TypeScript, Gemini, Replicate, ElevenLabs, FFmpeg

3dlabs.it.com

Architected and built an autonomous AI video-generation pipeline used by 5 teams / 40-50 users, orchestrating 12+ AI models across story generation, scene planning, image/video generation, TTS, sound design, and FFmpeg assembly to generate videos up to 15 minutes long
Designed a credit-reservation workflow and multi-tenant workspace isolation for projects, collaborators, and credit accounting
