The Thesis

Most people use AI. I build the systems that make AI work.

Every project I ship follows one rule: understand from first principles, then build from scratch. No LangChain. No LangGraph. No magic abstractions. Just Python, clear architecture, and hard-won intuition about what actually matters in production.

What I've built in 2026:
  ├── 18 AI agent sessions (perception → memory → decision → action)
  ├── A multimodal vision-language model (Gemma-270M + CLIP, trained from scratch)
  ├── ResNet-50 on ImageNet with multi-GPU DDP (one of ~10K people who've done this)
  ├── A screenshot-to-website AI pipeline (6 agents, real-time WebSocket UI)
  └── Production LLMOps infrastructure (FastAPI → Docker → K8s → Prometheus)

What I Ship

🧠 Agentic AI — From Scratch

4-layer cognitive architecture: Perceive → Remember → Decide → Act

I don't use agent frameworks. I build the framework. 18 sessions of progressively complex agent systems, each one teaching a different architectural pattern.

Agent Architecture:
  ├── Perception (Gemini Vision + structured extraction)
  ├── Memory (session logs + vector search + summarization)
  ├── Decision (multi-step planning with tool selection)
  └── Action (MCP servers + sandboxed execution)

Key insight: An agent is just a while loop with good memory. Everything else is engineering.

👁️ Multimodal AI — Vision Meets Language

Gemma-270M + CLIP = A tiny model that sees and speaks

Built a complete vision-language model from scratch. Combined a 270M language model with CLIP vision encoder, trained on 157K LLaVA pairs on a single A100.

Pipeline:
  Image → CLIP ViT-Large (frozen, 428M)
       → Vision Projector MLP (trainable)
       → Gemma-270M + LoRA (trainable)
       → Text Response

  539M total · 18.6M trainable (3.4%) · 9hrs on A100

🏋️ Deep Learning — First Principles

ResNet-50 on ImageNet from scratch. Multi-GPU DDP. One Cycle Policy.

Not torchvision.models.resnet50(pretrained=True). The real thing — implementing every layer, training with proper recipes, scaling to 4× V100s with Distributed Data Parallel.

Results:
  ├── CIFAR-100: 73%+ top-1 accuracy
  ├── ImageNet-1K: 75%+ top-1 accuracy
  ├── Training: SGD + OneCycleLR + MixUp + CutOut
  └── Scale: Ring all-reduce across 4 GPUs

Philosophy: If you can't build it from scratch, you don't understand it.

🚀 LLMOps — Production AI Infrastructure

From model handler to Kubernetes deployment with monitoring

Complete production pipeline: FastAPI serving → Docker containerization → K8s orchestration → Prometheus monitoring → rate limiting → cost controls.

Stack:
  ├── Serving: FastAPI + uvicorn + async handlers
  ├── Containers: Docker multi-stage builds
  ├── Orchestration: Kubernetes + GPU scheduling
  ├── Monitoring: Prometheus + Grafana dashboards
  └── CI/CD: GitHub Actions → HuggingFace Spaces

Principle: You can't optimize what you can't measure.

💡 How I Think

class AgentArchitect:
    """The principles behind everything I build."""

    principles = {
        "first_principles":    "If you can't build it from scratch, you don't understand it",
        "no_magic":            "No LangChain, no LangGraph — just Python and clear thinking",
        "production_or_bust":  "A model in a notebook is a toy. Ship it or it doesn't count",
        "measure_everything":  "Prometheus for predictions AND cognitive load",
        "config_over_code":    "Change behavior via YAML, not rewrites",
        "small_teaches_big":   "A 270M model teaches the same architecture as a 70B one",
    }

    def build(self, idea):
        """The loop: understand → implement → ship → write about it."""
        understanding = self.study_from_first_principles(idea)
        implementation = self.build_from_scratch(understanding)
        production = self.deploy_with_monitoring(implementation)
        return self.write_the_blog(production)  # so others can learn too
