Hi, I'm StackOracle 👋

Full-Stack Engineer · Agentic AI & LLM Systems · Python Backend
Building production systems where the model is a component, not the product.


About

I design and ship end-to-end products: async Python services on the backend, typed React front ends, and LLM-powered agents wired into both. Most of my work sits at the seam between conventional software engineering and applied ML - retrieval pipelines, tool-using agents, evaluation harnesses, and the unglamorous infrastructure that keeps them reliable in production.

  • 🧠 Agentic AI & LLMs - RAG pipelines, tool calling, multi-step agents, structured output, prompt and eval workflows
  • Async backends - FastAPI and Django services built for concurrency, streaming, and long-running jobs
  • 🧩 Full-stack delivery - React and Next.js front ends against clean, versioned APIs
  • 🧪 Test-driven by default - the test suite is the specification; CI is the gatekeeper
  • ☁️ Cloud-native - containerised workloads on AWS and GCP, deployed through GitHub Actions

What I Work On

Area What that looks like in practice
Agentic systems Planner/executor loops, tool registries, guardrails, retries and fallbacks, token and cost budgeting
RAG & retrieval Chunking strategies, hybrid search, re-ranking, grounded citations, offline eval sets
Async APIs asyncio end to end - connection pooling, backpressure, SSE/WebSocket streaming, background workers
Data & ML Feature pipelines, model training and packaging, batch and online inference, drift monitoring
Polyglot persistence Schema design and query tuning across PostgreSQL, MySQL, MSSQL, and MongoDB; picking the right store per workload
Product front ends Next.js App Router, server components, streaming UI for token-by-token responses
Delivery Trunk-based development, GitHub Actions CI, containerised deploys, IaC, observability from day one

How I Build

  • Tests first. Red → green → refactor. Unit tests for logic, integration tests against real dependencies in containers, contract tests at service boundaries.
  • Types everywhere. Pydantic and mypy on the Python side, strict TypeScript on the client.
  • Async where it earns its keep. Concurrency for I/O-bound work; no ceremony where a synchronous path is clearer.
  • Small, reviewable commits. Conventional Commits, linear history, every change traceable to an issue.
  • Boring infrastructure. Reproducible builds, pinned dependencies, one command to run the stack locally.
  • Observability is a feature. Structured logs, traces, and evals shipped alongside the code they measure.
