Healthcare Logistics Platform
A healthcare logistics platform that connected patients with donors. I architected and implemented the flows and automations for a medical distribution network's logistics. The system handled the full process end-to-end: generating internal orders based on stock levels and availability pulled from multiple internal systems, matching those orders with patient requirements, integrating with Stripe for payments and FedEx for shipping, and tracking every step through to final delivery.
Event Analytics Dashboard
I worked on a comprehensive analytics and event tracking platform designed to give mobile app teams full visibility into user behavior across their iOS applications. The platform enables tracking of onboarding funnels, paywall performance, app sessions, feature usage, and app rating requests.
My primary responsibility was designing and building the entire stack, from the back-end infrastructure to the reporting portal. On the back end, I architected a RESTful API with secure authentication layers, JWT for dashboard users, and HMAC-signed requests for mobile clients, as well as a per-project API key system that allows iOS teams to integrate directly without going through the dashboard.
On the front end, I built the reporting portal in React: a full dashboard that presents all tracked data to users, including funnel visualizations, paywall analysis, session stats, and feature usage breakdowns. The portal consumes the API directly and is designed to give both technical and non-technical stakeholders a clear view of how their apps are performing.

High-scale Advertising Platform Optimization & Sharding
I worked on a high-traffic advertising network (millions of monthly users) that faced scalability issues in its PHP-based ad-serving infrastructure. Using New Relic, I identified performance bottlenecks across the application and database layers, focusing on slow queries, inefficient indexing, and high-load endpoints. Implemented query optimizations, indexing strategies, and improved data access patterns, resulting in a 10× improvement in database performance. Additionally, I designed and implemented a database sharding strategy to distribute traffic across multiple MySQL instances, significantly improving scalability, fault tolerance, and system stability under heavy load.
SSR Learning Platform with Redis Caching (Vue and Laravel)
Developed a video-based learning platform focused on mentoring and specialization. The architecture consisted of a Vue front end and a Laravel back end, with Sanctum authentication. Implemented server-side rendering (SSR) to improve SEO and reduce time-to-content for content-heavy pages. Introduced Redis caching for frequently accessed data and user-related actions, significantly reducing database load and improving response times. Worked on optimizing API interactions and ensuring smooth integration between frontend and back end while maintaining performance under growing traffic.
High-traffic Game Portal Network with Static Generation & Caching
Built and maintained a network of browser-based gaming websites serving over 10,000 daily users. Developed a Laravel-based system that dynamically generated multiple static game portals from a centralized database, each with its own templates, rules, and configurations. Designed and implemented custom Nginx configurations for each site to optimize caching strategies, static content delivery, and request handling. This architecture enabled efficient scaling, reduced back-end load, and ensured fast page delivery across all portals.
AI-powered Environmental Intelligence Platform
I built an AI-powered environmental intelligence platform that provides early warning of drought and wildfire risk using satellite remote sensing and ground weather station data. I designed and implemented the full system architecture: satellite data ingestion (Copernicus Sentinel-2 NDVI), weather station integration (AEMET OpenData API with 21 stations), z-score anomaly detection engine, composite risk scoring for both drought and fire, multi-tier alert system, REST API (FastAPI), and interactive map visualizations (Folium). I also implemented sub-localization with 25 monitoring zones and validated against 6 known historical events — 100% detection rate: drought detection averaged 149+ days before official declarations, wildfire risk flagged 35+ days before ignition.
Legal Compliance & Litigation Management Platform for Public Institutions
I worked on a compliance and litigation management platform designed for public institutions, helping them track court cases, audit findings, and regulatory deadlines in one centralized system.
My responsibilities spanned back-end development and the React front end. On the back end, I designed and implemented the full architecture using Node.js (Express) and PostgreSQL with Sequelize ORM, including RESTful API endpoints, session-based authentication with JWT support, and background job processing powered by BullMQ and Redis for asynchronous tasks such as email notifications and scheduled litigation updates. I managed deployment and infrastructure on AWS, using CloudFormation (SAM) templates to provision VPCs, RDS instances, and S3 buckets, along with AWS SES for transactional email delivery.
A core part of the project was the integration with the Romanian court system (JUST portal), where I engineered SOAP-based XML queries to automatically import and sync litigation case data (including court details, parties, hearing stages, and solutions) on a recurring schedule. The platform also features a robust notification system with MJML email templates, a multi-role access model (Admin, Principal, Secondary users), among others.
