Victory O.

• Designed and implemented a Secure Payment Token Connector (PCI-Proxy ↔ Twilio Pay), enabling compliant payment data handling over telephony.
  Led security controls in line with PCI DSS, ensuring tokenized, zero-trust architecture.
  Built a flexible integration framework to support future payment providers.
  Result: Reduced risk exposure and enabled secure voice-based payments—a core feature for voice commerce.
• Contributed to LLM-based Intent Classification, boosting natural language understanding accuracy for user utterances.
  Researched on the possiblities of llm based intent classification and later implementing production-ready classification systems.
  Result: Removed the need for traditional NLU training, significantly reducing time to production for customer bots.
• Spearheaded LLM-powered Slot Extraction for voice assistants, allowing dynamic slot value extraction via natural language prompts.
  Designed fallback logic, type validation, and error handling for flexible yet safe slot capture.
  Result: Reduced reliance on rigid intent schemas; empowered cross-industry NLU customization.
• Led architecture and rollout of CallGuard Lifecycle Manager, managing critical voice event timing and flow for PhoneV2.
  Built a resilient state machine to handle race conditions and terminal event filtering.
  Added observability through intelligent logging and state transitions.
  Result: Dramatically improved call stability and platform reliability.
• Developed the Audit Dialog Analyzer and restructured legacy audit logs, enabling customers to clearly track changes and actions within their product.
  Result: Improved visibility into system events, enhanced compliance support, and empowered users with actionable audit insights.

• Led backend feature development and platform improvements using Go, Node.js, and TypeScript within a high-scale, headless commerce environment.
  Contributed to core services powering API-first commerce experiences for global enterprise clients.
• Improved performance and observability by analyzing MongoDB slow queries and implementing indexing strategies.
  Result: Boosted query speed and reduced load on backend systems, directly improving API response times for customer storefronts.
• Wrote detailed RFCs and architectural design documents to guide development across teams.
  Impact: Enabled consistent design decisions and facilitated alignment across engineering squads.
• Created a security plugin in Go to replace static secrets with dynamic token-based mechanisms.
  Result: Eliminated key security risks and aligned system behavior with modern best practices.
• Maintained and enhanced internal communication tooling, reducing friction between distributed teams and improving dev workflow efficiency.
• Collaborated cross-functionally with frontend, DevOps, and product teams to ensure seamless delivery of complex features.
  Impact: Drove successful integration across system boundaries and accelerated product iterations..
