AI Engineering · Building in public

A roadmap, not random experiments.

Four production-focused projects that progress from retrieval systems and agents to workflow orchestration and enterprise-scale AI architecture — each built with the same engineering principles as modern software: scalability, observability, security and cost-efficiency.

PROJECT 01 · RAG

Enterprise Knowledge Assistant

Organizations store valuable information across documents, wikis, databases and PDFs — finding accurate answers quickly is hard.

  • Multi-source ingestion + hybrid search (vector + keyword)
  • Context-aware retrieval with citation-based responses
  • Conversation memory, access control, evaluation & observability

PROJECT 02 · AGENTS

Multi-Agent Research System

Research means gathering from many sources, validating findings, synthesizing insights and generating recommendations.

  • Specialized agents that research, validate and analyze
  • Planning & reasoning, agent communication, tool calling
  • Human-in-the-loop workflows and agent evaluation

PROJECT 03 · WORKFLOW

AI Workflow Automation

Businesses spend significant time on repetitive workflows involving multiple systems, approvals and manual decisions.

  • Automated task execution + AI-assisted decision-making
  • Workflow routing, tool integrations, event-driven processing
  • Human approval checkpoints and production monitoring

PROJECT 04 · CAPSTONE

AI Engineering Platform

Building AI systems requires orchestration across models, agents, retrieval, evaluation, deployment and cost.

  • Multi-model support + model routing + agent orchestration
  • RAG, evaluation framework and monitoring dashboards
  • Cost tracking, experiment management, deployment pipelines
