Architecting systems that deliver scale, speed & clarity.

I am Arun Kiran Patro. Currently UI Architect at Aries (Aries.com), a US-based trading broker, owning the entire web estate. Over 15+ years across Aries, Oracle Cloud, and PayPal, I architect high-performance trading canvases, cloud IAM platforms, and mission-critical FinTech.

I bridge high-level system design with hands-on technical execution: from offloading chart websockets to Web Workers, to eliminating technical debt across hundreds of files, to authoring an issued US patent on dynamic GraphQL introspection.

Current Engineering Leadership

Leading the Web Stack at Aries.com

As UI Architect for a US-based trading broker since Jan 2026, I own the entire frontend web architecture, delivering high-frequency trading tools, native AI/voice assistants, and institutional onboarding.

Infinite Canvas & Cross-Browser Sync

Freeform infinite canvas with 60fps pan/zoom, widget rail, color-coded widget linking, and deterministic cross-browser/multi-tab content synchronization across trading monitors.

AI-Assisted Development

Pioneered AI-assisted developer workflows: modernized 314 files to strict TypeScript type safety, rapidly generated 90%+ unit test coverage, and automated design token extraction.

Native AI & Multimodal Voice

AI chatbox with tool-call rendering and interactive embedded charts, plus conversational voicebot with animated voice orb UI and real-time interim transcript streaming.

Design System & Institutional Ops

Built aries-web-library with shadcn UI, Plaid Layer instant onboarding, entity/trust accounts, and Client Center with AG Grid activity tables and ACH/wire flows.

Issued Patent Spotlight

A patented architectural solution for navigating complex enterprise data sources through dynamic schema introspection and unified interface abstraction.

US Patent: US12339836B2 • Oracle International Corp • Issued June 24, 2025

Datasource Introspection UI for GraphQL API Schema & Resolver Generation

Co-invented by Arun Kiran Patro at Oracle. Built the interactive User Interface to introspect diverse backend datasources (databases, REST APIs) and allow developers to visually select database schema objects, REST objects, or interfaces to automatically generate complete GraphQL schemas and resolver functions without manual SDL or boilerplate code.

Featured Engineering Case Studies

Production systems delivered under strict enterprise constraints, high transaction volumes, and regulatory requirements.

PayPal • High-Scale FinTech

Unlocking High-Value Payments Through Compliance Architecture

The Challenge

Payments above $3,000 were halted due to complex regulatory verification requirements, costing massive transaction volume across Web, iOS, and Android clients.

The Architecture

Architected a unified compliance capture flow across mobile and web without disrupting the payment checkout funnel. Used synchronized feature flags and fine-grained telemetry to monitor every transaction in production.

  • ✓$800,000 per week in recovered transaction volume.
  • ✓140% growth in payments greater than $3,000.
  • ✓Zero major incidents during global cross-platform rollout.
COMPLIANCE PIPELINE
1. Initiate > $3K Payment
2. Dynamic Regulatory Check (Flags)
3. Inline Identity Validation
4. Instant Settlement Approval

Inserted compliant verification without checkout drop-off.

Enterprise CRM • Global Operations

Reducing Support Costs Across 200,000+ Daily Calls

The Challenge

Customer support agents operated across fragmented legacy screens and disjointed toolsets. High cognitive overhead resulted in long handling times and steep training costs.

The Architecture

Redesigned the agent workspace into an intelligent, guided operating flow with contextual data panels and widget-driven dashboards. Unified disparate backend services into a single aggregation layer with full observability.

  • ✓30 seconds saved per call across 200K+ daily interactions.
  • ✓Millions of dollars saved annually in operational support cost.
  • ✓Drastic reduction in onboarding ramp-up time for new support staff.
WORKFLOW CONSOLIDATION
Before: 4+ Separate Legacy Screens & Manual Lookups
↓
After: Unified Single-Screen Guided Flow

Guided execution replaced chaotic multi-tab context switching.
