FCA-NVIDIA AI Sandbox Partnership & Global Platform Infrastructure

• Delivered mission-critical infrastructure for FCA-NVIDIA AI Sandbox partnership launch within 1-week deadline - engineered new module (Vue.js/Node.js/GraphQL) enabling global financial institutions to experiment with AI tools in regulatory-compliant environments, directly supporting FCA's "Supercharged Sandbox" initiative presented at London Tech Week (June 2025) and establishing NayaOne as official FCA technology partner alongside NVIDIA.
• Architected automated sandbox provisioning system (Vue.js/Node.js/PostgreSQL) serving 80+ global tenants across 5 continents—deployed 36 pre-configured fintech experimentation templates spanning various ecosystems, reducing enterprise deployment from 2-5 days to <1 day (for 95% of projects) and enabling sales team to deliver instant demos for new clients.

AI-Driven Product Intelligence & Vendor Onboarding Optimization

• Engineered automated session analysis system (Python/PostgreSQL/Gemini API) processing 35K+ user sessions from enterprise clients - completed comprehensive UX audit in 1.5hrs ($7 cost) vs. 50-100hrs manual effort, identified vendor onboarding as critical failure point (70% abandonment rate), and presented data-driven business case to CEO securing Q3 roadmap approval and budget allocation for full redesign.
• Led 5-person engineering team implementing vendor onboarding redesign (Vue.js/Node.js) based on AI-identified UX bottlenecks - reduced abandonment from 70% to <5% across all post-launch vendors, eliminated 206-309 annual CS hours previously spent on manual vendor assistance, and established repeatable AI analysis framework now applied to additional product workflows.

Team Leadership & Engineering Management

• Developed a team member from a non-technical manual QA role into a productive Mid-Level Web Developer over an 18-month period. Provided structured mentorship, 1-on-1 coaching, and code review that enabled their progression through automated QA (Cypress) and ultimately expanded the team's core engineering capacity.
• Lead 5-person engineering team through daily standups, sprint planning, and technical prioritization discussions, translating CEO and Customer Success requirements into engineering roadmap.
• Conduct daily performance reviews for 3 engineers, providing code review feedback and technical mentorship to support skill development.
• Collaborate with Customer Success team on product strategy presentations, aligning engineering capabilities with client requirements and regulatory compliance needs.

Platform Performance, Security & Architecture

• Eliminated critical GraphQL N+1 query bottleneck threatening platform stability for clients - refactored 84 queries in production API serving 300+ daily users by replacing TypeGraphQL decorators with optimized raw SQL joins and implementing Prisma data loaders. Reduced resolver response times 70% (250ms→75ms) and resolved escalations from Tier 1 financial institutions that threatened contract renewals.
• Led 3-month Keycloak SSO integration (50% contribution) enabling enterprise identity management for Lloyds Banking Group and other tenants. Implemented OAuth 2.0 authentication flows, automated token refresh mechanisms, establishing enterprise-grade security standard now deployed across 80+ tenants and enabling platform to meet stringent financial services compliance requirements.
• Architected enterprise monorepo consolidation in 1-week migration unifying 3 separate codebases into single development environment (Turborepo/Vite/TypeScript). Created 12 shared packages for UI components, API clients, etc. eliminating 30%+ code duplication across frontend applications, establishing single source of truth for 5-person engineering team, and accelerating cross-application feature delivery.

Accessibility & Quality Infrastructure

• Secured 100% WCAG 2.1 AA accessibility compliance required for FCA partnership launch - architected end-to-end Playwright testing framework achieving 100% route coverage across 3 applications, implementing 76 automated accessibility tests that enforced zero-violation policy and enabled regulatory approval for the release before "Supercharged Sandbox" initiative presentation.
• Established comprehensive E2E testing infrastructure (33% contribution) covering 500+ test cases across client and internal applications - containerized testing environment (Docker/GitLab CI) executing parallel test suites on every merge request, providing automated quality gates that protected core functionality and reduced manual regression testing cycles for 2-person QA team.

• Developed 2 customer-facing frontend applications for internal loyalty rewards platform, including personal account portal and rewards catalogue with spend-points functionality.
• Built interactive analytics dashboards with 3+ chart types (line, bar, pie) for customer behavior tracking, implementing router-based multi-page forms for data collection workflows.
• Integrated Microsoft Excel upload/download functionality enabling bulk data operations for rewards management and customer import/export across platform instances.
• Implemented customizable UI system supporting per-client palette configuration, internationalization (i18n) for multiple languages, and toggleable feature flags for different customer requirements.
• Architected SSO authentication backend service using Node.js and Keycloak, enabling unified identity management across university's digital learning ecosystem.
• Mentored 2 junior frontend engineers from August 2020 to May 2021, conducting code reviews and providing technical guidance that supported their progression to mid-level engineers within 6 months.
