💼 Professional Journey & Achievements

🎯 Current Role

_{Since October 2025 • Remote (London, UK)}

🏢 Professional Experience & System Architecture

🚀 Senior Full Stack Engineer @ NexaQuanta

Full-time • Remote (London, UK)

Full-Stack Development & Platform Engineering:

📊 CRM & Product Reporting System

Challenge: Lack of centralized reporting capability for business intelligence
Solution: Built comprehensive reporting module with email-based delivery supporting CRM and Product analytics
Impact: Enabled self-service reporting for sales and operations teams, improved business visibility into customer interactions and pipeline metrics

🗄️ Enterprise Database Schema Migration

Challenge: Incomplete database schema limiting cross-system data integration
Solution: Designed and executed complete database schema migration achieving 100% parity with source system
Impact: Enabled complete dealer hierarchy tracking, unified data management, established foundation for real-time synchronization and business intelligence

🗓️ Aftersales Appointments Management System

Challenge: No centralized appointment management for aftersales workflows — advisors had no way to create, track, or link appointments across HCI, Payment, and Triage modules
Solution: Built a complete appointment lifecycle module with multi-step creation forms, fly-out detail panels, status tags, advanced filtering/sorting, cross-module linking, and re-assignable "Assigned To" fields backed by SSO user lookup
Impact: Enabled full aftersales workflow management for dealer groups, appointment linking across HCI/Payment/Triage, real-time status tracking, and 60+ merged MRs delivering the feature end-to-end

📹 CitNOW Video Library & Status Integration

Challenge: No visibility into video status (Sales & Workshop) within the dealer portal — advisors had to switch between systems to track video progress
Solution: Built a dedicated video library page with filtering/sorting by status, CitNOW Sales and Workshop integration, NGD URL generation for direct video access, isolated filter state between Aftersales and Sales pages, and mobile-responsive design matching Figma specs
Impact: Unified video management across Sales and Aftersales in a single portal, eliminated context-switching between systems, real-time video status visibility for all advisors

📥 Enterprise Data Import Pipeline (IC5 → IC4)

Challenge: No mechanism to migrate legacy IC5 customer and appointment data into the new portal — manual entry was infeasible at scale
Solution: Built a full CSV-based data import pipeline with upload UI, server-side validation, duplicate detection (email uniqueness enforcement), appointment status mapping, import summary with invalid/valid record breakdown, and performance-optimized batch processing
Impact: Enabled seamless migration of enterprise customer and appointment datasets, prevented duplicate records with global uniqueness enforcement, reduced import processing time significantly with batch optimization

🏢 Multi-Dealer Org Scoping & Dual-Database Architecture

Challenge: Portal lacked proper dealer/org scoping — queries returned data across all organizations without isolation, creating data leakage risk in multi-dealer environments
Solution: Integrated orgId throughout the portal with comprehensive dealer scoping for all IC4/IC5 lookup queries, dual-database querying strategy for cross-system appointment resolution, and dealer hierarchy tracking
Impact: Proper data isolation per dealer organization, eliminated cross-org data leakage, established foundation for scalable multi-tenant dealer group management

🔒 Security Hardening & Generic Audit Module

Challenge: Critical query injection vulnerability identified by Aikido security scan in the presenter service; no audit trail for user actions across the platform
Solution: Patched the injection vulnerability in the presenter microservice; architected and implemented a generic audit module with activity tracking refactor, reusable across all platform entities
Impact: Eliminated critical security vulnerability (CVE-level), established comprehensive audit trail for compliance and forensic traceability across all user actions

⚙️ Redis Cluster & Infrastructure Hardening

Challenge: Redis Cluster CROSSSLOT errors crashing BullMQ job queues; optional auth not handled
Solution: Fixed CROSSSLOT key violations for BullMQ sso-import queue, added graceful Redis authentication handling
Impact: Stable job processing in clustered Redis environments, zero queue failures from infrastructure misconfig
