Judex — Evidence-Based Investment Copilot

Everydecision traceable — id, rules-version, verdict, outcome, grade

Goal

Build a daily investment copilot that recommends with written reasons, asks for a human verdict, executes only on approval — and grades its own calls, and the user's, in public. Live on real portfolios, multi-tenant, pre-launch.

Backstory

Retail investors drown in noise and act on impulse; AI investment tools answer with demos that were never trusted with real money. The interesting problem was not the model — it was the operating loop: who decides, who executes, and who gets graded.

So Judex was built for the hardest first customer — myself — in production from the first week, with every design decision made next to the problem: a two-minute daily brief, a one-tap approval, a ledger that remembers every verdict. Once the loop held up under real use, it was made multi-tenant and opened to family and friends.

Details & Artifacts

Solution:

  • Two decision engines on a Databricks medallion lakehouse: a Control Tower defending holdings via a graded risk ladder, and an Opportunity Finder that qualifies on strength and buys on weakness.
  • Strict division of labour: rules decide, AI only explains — the LLM writes readable reasons, never picks the trade; missing data is excluded, never guessed.
  • Human-in-command execution: email brief → one-tap approval → broker execution on a dedicated agent account; the main account is record-only.
  • Full audit spine: every recommendation carries an id and a rules-version hash; a ledger grades system calls and user verdicts, including the what-if for declined advice.
  • Multi-tenant with a 24-check tenant-isolation suite run against the live system after every relevant deployment.
  • Operated, not just shipped: versioned rule revisions from live evidence, cost-tuned across three clouds.

Impact: In daily production since mid-2026 on real portfolios; every decision — machine and human — traceable end to end; rule changes shipped from field evidence without rewriting history.

Stack: Databricks (Delta, Unity Catalog) on Azure, Windmill, Next.js, PostgreSQL, OCI, Terraform, eToro API, LLM explanations.

Artifacts: Published method statements, a dated end-to-end case file, decision-trace portal, monthly scorecard. judex.simplificare.ch (pre-launch).

SaaS Core Banking Suite Cloud Transformation

$4T+AUM provisioned across 25+ banking clients; weeks to hours

Goal

Transform the SaaS Core Banking Suite architecture to leverage cloud-native capabilities, optimize workload placement across hybrid and multi-cloud environments, and deliver a standardized, automated, and compliant provisioning framework for 25+ banking clients.

Backstory

The existing SaaS platform was hosted entirely on a private cloud, requiring the integration of complex stacks — from servers to switches, routers, operating systems, and databases — in collaboration with multiple third-party providers.

The scale was immense: 1,700 databases, 30,000 virtual servers, and 5,000 physical servers. The monolithic Oracle-based Core Banking Suite spanned multiple banking domains, with business logic deeply embedded and tightly coupled to the data layer. Several attempts to re-platform the data stack to cloud DBaaS had failed due to technical dependencies and economic constraints.

Systems of Engagement for business services were layered on top via APIs and UI services, but lacked portability and flexibility to adopt hybrid or multi-cloud strategies.

Details & Artifacts

Solution:

  • Design data layer on Oracle Cloud’s Dedicated Region Cloud@Customer (DRCC) to maintain regulatory and performance compliance while introducing cloud-native capabilities.
  • Migrated container-based Systems of Engagement to each client’s preferred hyperscaler (Azure, AWS, OCI, or GCP).
  • Defined hybrid blueprints to optimize workload placement, service selection, and Infrastructure-as-Code strategies.
  • Designed and implemented Low Code Cloud Topology Automation Orchestrator for IaC authoring.
  • Established a Unified Data Model to abstract cloud-specific service variations, enabling standardized, modular provisioning.
  • End-to-end Azure Data solution ingesting on-prem Oracle Exadata data via ADF and GoldenGate into ADLS, transforming it with Databricks Delta Live Tables, and delivering governed analytics and ML insights through Power BI and Feature Store
