Outbound Lead Generation & Automation System (Email + LinkedIn) I built a complete outbound system to generate and convert high-quality B2B leads using email and LinkedIn automation. The system starts with ICP-based lead sourcing, targeting companies by size, revenue, industry, and C-level roles. Leads are enriched, segmented, and automatically routed into a structured outreach flow. I designed a 6-step email sequence where messaging evolves at each step to increase reply rates. LinkedIn actions are timed between email touches to create a natural multi-channel outreach without overlap. The main challenge was coordinating multiple tools while maintaining deliverability and clean data flow. I solved this by building a centralized automation layer that handles sequencing logic, delays, and real-time updates across systems. A lightweight CRM tracks every lead from first contact to final outcome, including replied, interested, and not interested. This provides clear visibility and allows continuous optimization. The system is structured for scalability and simple handoff, so it can be managed without technical dependency.

Built a feedback and workflow management system focused on collecting, organizing, and prioritizing user-driven inputs across multiple channels. The platform provides a structured interface where feedback items move through defined stages, enabling teams to track status, engagement, and impact in a clear and scalable way. On the backend, I designed data models and filtering logic to support advanced querying, segmentation, and lifecycle management of feedback items. Implemented role-based access control and admin-level configurations to manage permissions, visibility, and workflow transitions. This ensures that internal teams can efficiently manage large volumes of data while maintaining consistency and control. On the frontend, I focused on building clean dashboards and interactive views that surface key metrics such as user reach, engagement, and revenue impact. I also implemented public-facing and read-only views, allowing external users to submit feedback and track updates without direct system access. This improves transparency while keeping the system secure and well-structured.

I built a workflow management system focused on tracking projects from start to completion with clear visibility and control at every stage. The core of the system is a multi-role dashboard that presents real-time data in a structured way, allowing different users to quickly understand project status, performance metrics, and operational health without digging through raw data. On the backend side, I designed structured data models and lifecycle flows to manage how tasks move through different stages (creation → in-progress → completed). I implemented role-based access control and admin-managed configurations so the system can handle multiple users, permissions, and dynamic updates reliably. The goal was to make the system scalable and maintainable while keeping the logic clean and predictable. For the frontend, I focused on building intuitive dashboards and reporting layers that translate complex data into simple, actionable insights. I also implemented shareable, read-only views so external users can track progress through a secure link without needing full access. This improves transparency while maintaining control over the system, which is critical for B2B workflow tools.
