Oversaw application architecture, development, deployment, andmaintenance.Engineered end-to-end delivery of a multi-tenant cybersecurity platform,encompassing architecture, backend and frontend development,integrations, and deployments.Developed core backend services utilizing PHP and Laravel, while creating amodern Vue 3 + TypeScript frontend with a multi-themed UI andconfigurable widgets.Designed a multi-tenant architecture featuring multiple client databasesalongside a shared/common database, ensuring tenant-aware data accessand isolation.Managed deployments across environments, leveraging Docker for localdevelopment and Kubernetes for server deployments, significantlyenhancing release reliability and repeatability.Constructed robust data ingestion pipelines through API integrations and fileimports, integrating external security platforms including Qualys,SecurityScorecard, Tenable, UpGuard, and Rapid7.Executed Jira integration for bi-directional syncing of client findings to JiraIssues and automated Jira project setup via API requests.Facilitated SSO/Identity Provider integrations with Microsoft Azure/Entra ID,Okta, Google, Keycloak, Amazon Cognito, and GitHub, incorporating secureauthorization flows and role mapping.Implemented ACL authorization across the platform to manage access bytenant, role, and feature.Created a scheduling system for automated jobs (imports, syncs, reports)featuring configurable schedules per tenant.Processed large datasets using background processing techniques forimports (Excel + external connectors), exports (Excel/PDF), chunking,retries, and failure handling.Instituted a deduplication and aggregation system to consolidate identicalissues from various sources (external connectors, Excel imports, and in-appentries) into a unified record.Delivered advanced reporting dashboards with severity/status breakdownsand tailored widget-driven views for each tenant.

Directed backend development of applications utilizing Laravel.Conducted unit testing and monitored and resolved Sentry issues.Revamped existing code for optimization and conducted performanceimprovements.Addressed and resolved bugs promptly

Served as a Full Stack Developer on multiple projects.Engineered admin panels utilizing Laravel and Laravel Nova, applying datatransferobjects (DTO) across several layers (interface->services->domain->model/database) to ensure clean object-oriented structure, ease ofreadability, and extensive validation.Adopted Domain-Driven Design (DDD) and Test-Driven Development (TDD)methodologies.Contributed to frontend development using Vue.js, JavaScript, jQuery, andTailwind CSS.Utilized version control systems including GitHub and BitBucket.Managed application deployment using the Linux console and Docker.

Acted as a backend developer on a comprehensive Project Management |Ticketing | Timesheet platform.Developed backend solutions using PHP, Laravel, MSSQL, MySQL, andRedis.Engineered modules for project planning, timesheet management, and taskmanagement, incorporating complex resource handling (raw inputs, views,data aggregation, and correlation algorithms) with extensible classstructures.Contributed to frontend development leveraging JavaScript, jQuery, andweb components (custom elements/custom HTML tags).Gained experience working with DevExpress technologies.
