Backend engineer.
Also an app maker.

I’m at Enterprise AI Group in Sydney. Before that, TikTok and FUJIFILM. Outside work, I build Mac apps, an iPhone app, and tools for developers.

Autonomous UI-Exploration Agent

Test a live admin interface without handwritten scripts or changes to real data.

15.6%

reachable-state coverage, up from 5.9%, backed by 895 offline checks

How it works

An agent that maps the surface into a graph of pages and actions, ranks the journeys through it against real user click analytics and checks the backend response behind each one. A companion LLM service turns requirements documentation into executable cases. It runs fail-closed and view-only by default, with the final create gated behind a second explicit flag.

MACOS APP2026

Switchboard

Put everyday Mac controls one click away, from per-app audio to the clipboard, without digging through settings.

10+

real users, me included. It runs on my Mac all day.

How it works

A macOS menu bar app for per-app volume and output routing, clipboard history, system monitoring and everyday tweaks, shipped as a signed DMG across five releases. Core Audio taps handle app routing, with playback falling back to the default output when a device disconnects. Clipboard history stays in memory and clears on quit.

APP STORE2026

Kerbside NSW

Read a NSW parking sign and work out when the car has to move, on a phone that may have no signal, without sending a photograph of the street anywhere.

ZERO

network calls, with six architectural invariants enforced by build-failing tests

How it works

A solo iOS app on the App Store that reads signs entirely on device. A two-pass Vision pipeline locates the pole, runs rectangle detection on that crop and splits stacked plates by colour, feeding a deterministic parser the on-device model can never override: it is consulted only on panels the parser rejected. No analytics, no third-party SDKs, an empty privacy manifest.

Nomi

Run a capable assistant on a laptop without an API key, an account, or a single token of the conversation leaving the machine.

LOCAL

inference only. No API key, no account, and nothing leaves the machine

How it works

A macOS assistant in the MacBook notch, running a 14B model locally through MLX. A resumable downloader verifies model files, and a memory-aware manager keeps one model resident. The agent loop validates tool calls, applies confirmation by risk, and bounds execution by time and step budgets. Tested across 167 tests in 38 suites.

ContractGuard

Catch a breaking API change while it is still a pull request, not after a consumer breaks in production.

85 ms

to diff a 1,000-path document at p50; a provider retry fails on a unique index

How it works

A GitHub App with semantic diff engines for OpenAPI 3.0/3.1 and GraphQL SDL that grade each difference by severity, so the same nullability change is breaking on a request body and compatible on a response. An authenticated principal runs through every resolver and every query is scoped to the caller's installations, leaving no unscoped read path.

FUJIFILMPROPRIETARY · 2026

Internal AI Engineering System

Engineering context sat scattered across the knowledge base, system documentation and decades of legacy source.

0.5 DAY

of engineering work, down from one week, with zero regressions on the migration

How it works

A two-phase system: retrieval grounds each request in those sources, then execution plans and runs the task against the target codebase. Applied to the Infor Aurora ERP FP27 migration, where it cleared critical defects and restored charge-correction workflows. Selected for a company-wide international presentation in Singapore.

about me.

AT WORKFlip the card

Mehul Fursule, Junior Backend Engineer at Enterprise AI Group, Sydney, Australia.

Find me on GitHub

I'm a Junior Backend Engineer at Enterprise AI Group in Sydney, working on Python and TypeScript services for enterprise clients. Most of my work sits behind the interface: services, APIs, and the tools other engineers use.

At TikTok, I built an autonomous testing agent adopted by 3+ teams. Before that, FUJIFILM promoted me from intern to developer, and the AI engineering tools I built took me to Singapore for a company-wide presentation.

I also build apps outside work: a parking app on the App Store, a local AI assistant for the Mac, and Go platforms for API safety and webhook delivery. I'm completing Computer Science and Commerce at UNSW, graduating in November 2026.

My work so far, alongside my degree.

  1. Enterprise AI Group

    Junior Backend Engineer

    CurrentSEP 2026 - PRESENT

    Sydney

    • Python
    • TypeScript
    • Microservices
    • REST APIs
    • CI/CD
    • Building backend services and REST APIs on a microservices platform for enterprise clients, from design and tests through code review and deployment.
    • I use AI coding agents, then review the code, write tests, and fix defects before release.

  2. TikTok

    Software Development Engineer Intern

    JUN 2026 - SEP 2026

    Sydney

    • Python
    • Go
    • Microservices
    • Apache Thrift RPC
    • Shipped an autonomous UI-exploration agent adopted by 3+ teams. Reachable-state coverage grew from 5.9% to 15.6%, backed by an offline suite that grew from 174 to 895 checks and guards that block unsafe actions by default.
    • Built an LLM service that turns requirements into executable test cases, plus 12 skills for the team's QA bot. Both spread to other teams.
    • Recovered 50+ blocked cases in an 870+ case suite by tracing failures across access rules, regional connectivity, and an Apache Thrift client/server schema mismatch.
    • Built monitoring across production and pre-production, including a fix for an outage that could report zero targets down. Dedicated test nodes cut end-to-end runs from 45+ minutes to 7 minutes, followed by a further 3x speedup through parallelisation.

  3. FUJIFILM Business Innovation Australia

    • Promoted from intern to developer. Selected to present company-wide in Singapore after delivering AI engineering tools for a major ERP migration, restoring critical workflows with zero regressions.
    • Built a retrieval-and-execution AI system grounded in internal documentation and legacy source. A week of engineering work became half a day.
    • Designed REST APIs and built two production React dashboards: fleet analytics over Snowflake and an operations monitor covering 30+ enterprise systems.
    • Shipped 20+ AWS Lambda functions and replaced a 19-step workflow with a Python pipeline processing 300,000+ records each month. A full day of manual work became under 5 minutes.

  4. FUJIFILM Business Innovation Australia

    Software Engineering Intern

    JUN 2025 - DEC 2025

    North Ryde

    • Automated NSW Department of Education contract management and compliance workflows, cutting manual processing by up to 40% and document turnaround by 30%.
    • Built safety compliance modules with live alerting, used by 15+ departments.
