DWG—01What I do
SHT 02/07

A senior pair of hands, from blueprint to production.

I take on work where deep experience actually matters — the architecture calls, the hard integrations, the AI that has to survive real load.

A /

Architecture & Technical Consulting

System design, API-first architectures, and modernisation strategy for teams that need a seasoned hand on the blueprint before they build.

B /

AI Solution Engineering

Agentic workflows, RAG pipelines, and production-ready GenAI integrated into real enterprise systems — auditable and reliable, not demos.

C /

Fractional & Freelance Development

Full-stack delivery across Java, Node, React and React Native. I build, ship, and own the parts that are genuinely hard.

D /

MVP & Prototype Builds

From idea to a working product. Fast, pragmatic builds that let you validate with real users before you invest in scale.

Things I've designed and built.

Enterprise platforms, applied AI, and side projects shipped on my own time.

01
Applied AI · Voice agentClient preview

NDIS AI Lead Generation

An AI voice agent that phones new NDIS provider leads minutes after sign-up — qualifies them in conversation, checks live calendar availability, and books the meeting itself. Deployed to dev for client evaluation.

Event-driven middleware keeping HubSpot CRM and Odoo ERP in sync — signature-verified webhook ingestion, idempotent async processing, circuit breakers and retries, with Prometheus + Grafana observability. Live on Azure.

Ecommerce · Side projectIn build

Canberra Honey

A small-batch ecommerce platform helping a local beekeeper sell direct — a clean storefront and simple operations for a maker who'd rather tend hives than fight software.

Applied AI · RAGLab build

AI-Driven Research & Analysis Platform

A retrieval-augmented system that reads across large document sets and synthesises answers with structured, traceable outputs — built as a hands-on lab for production-oriented AI patterns: orchestration, latency, and error handling.

SHT 06/07
01

Understand

I dig into the real problem and its constraints — the business, the load, the edge cases — before a line of code gets written.

02

Architect

A clear, scalable blueprint: API-first, observable, and built for whatever you'll want to add next — including AI.

03

Ship

Production-ready delivery with the reliability and operational rigour that mission-critical systems demand.

— Mohammad Talah Sheikh
Solution Architect & AI Engineer, Sydney

I'm a Sydney-based solution architect and AI engineer. For sixteen years I've designed and delivered high-volume systems for some of the world's largest banks — the kind where downtime isn't an option and the audit trail matters.

Today I split my time between enterprise architecture and building things of my own: apps, SaaS, and AI solutions for people who want a seasoned pair of hands rather than a big agency. If you have a hard problem worth solving, I'd like to hear about it.
