Built

The infrastructure that runs Infraxus is built solo, by a finance operator. Five years of finance-systems work, applied here. The offer was prototyped through an extended engagement with an Australian information technology firm before the firm was launched.

  • Infraxus Portal

    app.infraxus.com Live

    Multi-tenant finance intelligence product with AI commentary, forecast modelling, and authenticated client dashboards.

  • Sales orchestration system

    app.infraxus.com/sales Live

    B2B sales infrastructure replacing a Clay-based stack at one-tenth the cost. Sonnet qualifier, Apollo enrichment, HubSpot orchestration, twelve-inbox cadence, autonomous LinkedIn outreach. Continuous Opus reasoning loop on a four-hour cadence surfaces patterns and risks via Pushover and morning briefings. Operator dashboard at app.infraxus.com/sales consolidates funnel state, pipeline reality, channel health, and cohort intelligence.

  • Multi-source financial data integration layer

    In development

    Direct integration layer between Infraxus Portal and the finance stacks SMBs actually run: Xero, banking via Akahu and Basiq, payroll, and supporting systems. Replaces the current Excel-template ingestion flow. Multi-source authentication, schema mapping, and reconciliation logic feeding the existing Portal data model.

  • Finance reasoning layer

    In development

    Portal feature in development. Continuous analytical pass over each client’s financial data, surfacing runway implications, anomalies, and pattern shifts through authenticated dashboard insights and operator briefings. Builds on the multi-source integration layer above; mirrors the architecture of the sales reasoning layer applied to client finance.

  • Board pack generator

    Refining

    Automated styled board-pack PDF generated from Portal data on a recurring schedule. First version live in the Portal. Refinement in progress on layout, narrative density, and recurring delivery cadence.

Questions this work tends to answer

  1. My accountant says we made money, so why can’t I find it in the bank?
  2. Which clients, jobs, or products are actually making money, and which ones are just keeping us busy?
  3. Can I afford this hire, or does it just make payroll harder?
  4. Are these numbers solid enough to make a decision, or am I still just going by feel?
  5. Can I afford this purchase right now, or am I borrowing from next month without realising it?
  6. If I step away for a week, what breaks before I see it?

Wellington2017–2020
Bachelor of Commerce, Accounting and Finance, Victoria University of Wellington. Certificate of Excellence. A− GPA.
Auckland and Barcelona2020–2023
Business Advisory at BDO. Hired out-of-cycle from a 250+ applicant pool during the 2020 COVID hiring contraction. Promoted through four roles in under two years; trained two graduate consultants while completing the CA programme; inherited the dedicated forecasting role for a 50-staff office under tenure. Engagements included multi-entity consolidations under operationally degraded internal finance, forensic accounting on a director’s-duties insolvency matter working directly with instructed counsel, and integrated forecast modelling for a proposed business that did not yet exist. Negotiated a remote engagement structure to relocate to Barcelona for the final twelve months.
Melbourne2023–2024
Finance Business Partner at a 130-staff mid-tier law firm. Ran the finance brief in board meetings during repeated CFO absences; owned the three-way forecast for ATO and lender reporting; sat across Remuneration Committee discussions including partner-pay analysis. Through one extended period in mid-2024, ran the firm’s finance function solo across CFO, finance manager, analyst, and payroll responsibilities, with one junior staff member supporting. Single-handedly migrated payroll and HR platforms inside one month. On more than one occasion produced analysis that contradicted the prevailing leadership view. The firm has remained an external advisory client since I left.
