About Paravision Lab

Paravision Lab — Independent GenAI Engineering Project

I design, develop, and deploy AI systems end-to-end for rapid prototyping and production.

Solo engineer focused on deterministic orchestration, evaluation, and production deployment.

What I built

Representative GenAI product directions I’ve implemented end-to-end, with production constraints in mind.

Each build is shaped around the problem. These are starting points, not templates.

Perplexity-Style AI Research Tool

Built a full-stack GenAI research platform that intelligently decides how to answer user queries: via direct LLM response, RAG retrieval pipelines, or external API calls. Implemented agentic routing with LangGraph, real-time streaming, and persistent user sessions in Supabase.

AI Video Ads Generator

Developed an end-to-end platform generating multi-variant ad scripts with avatar/voice selection, asynchronous video rendering, and persistent asset management. Implemented an event-driven architecture using Inngest for background jobs, retries, and durable execution.

AI Short Video Generator

Built a full-stack system orchestrating LangChain-driven scripts + TTS pipelines with non-blocking MP4 rendering via Remotion. Implemented an event-driven workflow where Supabase queues jobs and Remotion workers asynchronously render videos, storing outputs and user assets back in Supabase.

YouTube Analytics & Creative Tool (TubePulse)

Built an AI-powered platform for YouTube creators to generate thumbnails, analyze competitor content, and optimize SEO workflows. The system intelligently decides how to respond to user queries—direct LLM generation, retrieval from analytics pipelines, or external API calls—ensuring fast, context-aware insights. Implemented persistent user sessions, real-time thumbnail generation, and automated content scoring.

AI Logo Maker

Built an AI branding tool generating logo variations using LangChain prompt pipelines. Implemented an event-driven rendering workflow with Supabase-managed jobs and versioned logo history storage for persistent user sessions.

AI Interview Platform (EchoTalent)

Developed a voice-first AI interview system with dynamic question generation, real-time voice interviews, automated multi-dimensional scoring, and a responsive user dashboard. Event-driven architecture via Inngest handled background processing, session persistence, and async evaluation workflows.

Typical Development Workflow

A structured approach used across product builds, emphasizing deterministic orchestration, system evaluation, and observable AI behavior.

  1. 1

    Problem Definition & System Scope

    Define the AI workflow, system constraints, user interaction patterns, and evaluation criteria before implementation.

  2. 2

    System Architecture & Orchestration

    Design orchestration flows, tool interactions, retrieval pipelines, and state management to ensure deterministic and debuggable AI workflows.

  3. 3

    Implementation with Guardrails

    Implement AI pipelines with structured outputs, evaluation hooks, retries, and cost/latency controls.

  4. 4

    Deployment & Observability

    Deploy systems with monitoring, logging, streaming support, and observability hooks for debugging and evaluation.

Let's connect

I'm open to discussing system architecture, engineering trade-offs, and evaluation approaches demonstrated across these builds.

This includes failure modes considered, orchestration patterns chosen, and how the systems behave under async workloads.
