Deep Research Agent

Python + LangChain + LangGraph

Deterministic, reproducible research runsURL + document ingestion (HTML, PDF, DOCX, TXT, MD, CSV)Traceable artifacts for every run

Production-grade deep research agent that plans, fetches, and writes structured reports from URLs and documents with strict guardrails.

  • Tool-using workflows via LangChain / LangGraph with a Deep Agents-inspired design.
  • Fetch pipeline that handles HTML and the top 5 document formats with safe timeouts and size caps.
  • Runs produce plan.md, notes.md, sources.json, report.md and normalized source files under runs/<thread_id>/.
  • Guardrails: caps on max_sources, max_links_per_source, HTTP/model timeouts, token limits and retries.
  • Automatic artifact completion if report.md is missing after a run, using a tool-free model call.

Deterministic PDF ingestion into QdrantGrounded Q&A with citations and refusal guardrailsOps-ready doc lifecycle and diagnostics

DocOps automation agent for production-grade document ingestion, grounded Q&A with citations/refusals, and an audit harness for evaluation.

  • Ingestion pipeline that extracts, chunks, embeds and stores PDFs in Qdrant Cloud with deterministic chunk IDs and safe retry behavior.
  • Grounded answering layer that returns citations and refuses when context is insufficient instead of hallucinating.
  • Audit runner that produces JSON + Markdown reports for repeatable evaluation and iteration.
  • Doc lifecycle ops: registry list/get, export/import, rebuild from chunks, and delete that cleans up both chunks and registry state.
  • Ops utilities: retrieval debug, diagnostics, redacted config snapshot and cache cleanup CLIs/APIs.

How I Work

A practical, repeatable process for turning requirements into a stable, shippable product.

01

Understand the Problem

Start by understanding the problem properly: goals, constraints, edge cases. No assumptions—just clarity.

02

Clear Specification

Convert requirements into a compact specification: flows, data models, and failure scenarios documented upfront.

03

Design for Change

Build with change in mind so new features don't require rewrites. Scalable architecture from day one.

04

AI-Assisted Development

Use AI tools like Claude and GPT for speed, but personally handle all critical paths to ensure quality.

05

Root Cause Fixes

Test, observe, and fix issues at the root so they don't reappear elsewhere. Sustainable, long-term solutions.

Why Work With Me?

Senior-level execution, strong communication, and a bias for shipping stable systems—not demos.

Clarity over chaos

I reduce ambiguity fast: requirements, edge cases, and success criteria become a clear plan before code changes.

Built for change

I design systems that stay maintainable: clean interfaces, safe refactors, and production-grade reliability from day one.

Outcome-driven delivery

I optimise for shipped value: measurable improvements, fewer regressions, and a system you can confidently evolve.

About Me

Founder of 2 startups and former CTO. I build production-grade AI apps, data pipelines, workflow automation, and Stripe payments.

What I do (and how I do it)

I’m Waqas Raza, an AI-first product engineer. I don’t just bolt an LLM onto an app—I design reliable systems with guardrails, predictable costs, and controlled failure modes.

My background spans heavy Laravel platforms, modern TypeScript backends, Next.js frontends, and production Flutter apps. If you need someone who can move fast without breaking stability, that’s my lane.

Core competencies

  • Full‑stack web & mobile (Next.js, Node.js, Flutter)
  • RAG chat + support systems with reliable guardrails
  • ETL + data pipelines (Supabase/Postgres, Redis, queues)
  • Stripe subscriptions, Connect, payouts, webhooks
  • Background jobs, retries, idempotency, logging, performance tuning
  • Cloud + deployment (Docker, AWS/GCP, VPS)

Recent wins
