# Lukas Prinsloo (Luke)

Lukas Prinsloo (Luke) is a Software Engineer and Full-Stack & Systems Engineer (0-to-1 Product & Cloud Delivery) based in Cape Town, South Africa (Somerset West, Western Cape · UTC+2).

Core philosophy: **Responsibility as a Service (RaaS). I turn problems into production systems that deliver real outcomes.** RaaS is Luke's personal view of how software engineering has changed: writing code is no longer the scarce part, owning the production outcome from first conversation to verified release is, and auditability and governance are the cornerstone of that model.

He takes work from the first conversation through to a verified production release across the stack, covering React and Vue web applications, Node.js, Python, and TypeScript backend services, and AWS cloud infrastructure underneath, without needing to be chased.

## 6-Month Production Telemetry (Inner Reality)

- **62% Delivery & Releases:** Averaged 62% of total engineering delivery and production releases at Inner Reality across a multi-repo estate over a six-month window.

## CTO Endorsement

**Daniel Pettifor, CTO & Principal Architect, Inner Reality (20 August 2026):**
"Nothing he has taken ownership of has needed chasing. Where many developers wait for direction, Luke identifies what needs to happen, takes responsibility for the outcome, and drives it to completion."

## The Three Pillars of Delivery

1. **Product & Cloud Delivery:** Taking commercial briefs from a blank repository to live production. Owning the full lifecycle across web applications, backend APIs, and AWS cloud infrastructure, turning business requirements directly into deployed software that works for customers and partners.
2. **Agentic Delivery ("The Loom"):** Orchestrating custom engineering harnesses across Claude Code, Codex, and Antigravity with deliberate model context control and seamless on-the-fly provider switching. My system ("The Loom") routes the right model to each task with production boundaries enforced via policies, sustaining 62% of delivery and releases at Inner Reality.
3. **Auditability, Traceability & Governance:** Auditability, traceability, and clarity are the cornerstone of the RaaS model I have in mind for how software engineering has changed. Every agentic workflow records explicit decision paths, structured task ledgers, and verification proofs so engineering leaders can inspect how work was done and govern agentic systems in production.

## Engineering Dossier

- **Partner API & Campaign Runtime:** Built and shipped an external partner REST API in ten days for a Global Motorsport Partner alongside live campaign execution and automated budget controls, unblocking a flagship integration on a fixed commercial deadline while protecting campaign budgets.
- **3D & WebXR Campaign Studio:** Built a guided four-step spatial campaign studio with automated 3D asset validation, live previewing, and direct publishing, removing engineering as a launch bottleneck and onboarding self-serve paying clients.
- **Interactive 3D & AR Campaign Games:** Built and shipped browser 3D, AR, and interactive games (Three.js, PlayCanvas, 8thWall, React, Vue) alongside an iframe proxy preview harness across live client campaigns, turning creative briefs into smooth mobile player experiences.
- **Cloud Release & Deployment Pipelines:** Maintained and operated multi-repo AWS deployments (AWS CDK, Terraform, Lambda, CloudFront, GitHub Actions) and automated release checks across the production estate, turning manual deployments into repeatable releases that reach customers the same day.
- **Seven Day Emergency WebXR Rebuild:** Replaced a collapsed third-party AR vendor in seven days by building and shipping an in-house React and WebXR experience before launch, saving a committed commercial campaign from cancellation.
- **Live Campaign Analytics & Voucher Operations:** Built live campaign analytics pipelines, registration-to-claim journey reporting, and safe voucher pool management tooling in Python, DynamoDB, S3, and CloudWatch.
- **Automated QA & Pre-Release Security Gate:** Built Inner Reality's automated regression and integration test suite from scratch in Python, SeleniumBase, and Playwright, including end-to-end browser journey and OTP verification, plus automated pre-release checks across CORS, CSP, authentication boundaries, and session isolation.
- **GG Anvil (`https://goodgameanvil.com/`):** Independent multi-tenant esports ops platform on AWS Serverless (CDK, DynamoDB, Cognito/Discord OAuth, AWS Bedrock vision extraction with deterministic validation and human review), automating tournament result verification while holding ambiguous OCR reads for human review.
- **Local-First Meeting-to-Work Pipeline:** Open-source Python pipeline running three concurrent local models (Faster-Whisper, pyannote, Gemma via Ollama) in sub-0.5-second latency, under 5GB VRAM, and zero cloud calls, turning spoken meetings into structured specs and tasks on-device with zero cloud cost or data leakage.
