Experience

Homeowners' Association (HOA) Management SaaS

I took the lead in designing and developing an innovative cloud-hosted Homeowners' Association (HOA) management platform using Ruby on Rails (RoR). I created this platform to enhance efficiency and improve communication among homeowner associations, property managers, and residents.

I focused on streamlining workflows and automating processes that burdened traditional management methods. The software features fee and payment collection, offering a seamless financial transaction experience for users.

As the project architect, I defined the technical roadmap and ensured adherence to best practices in development and user experience. I led the engineering team through Agile sprints, facilitating regular stand-ups and retrospectives to keep the project on track and encourage collaboration.

Additionally, I contributed by coding core functionalities and integrating features to enhance user engagement and operational effectiveness. My focus on performance and scalability was vital as we navigated the timeline to deliver the minimum viable product (MVP). Ultimately, I ensured the platform met users' immediate needs while establishing a solid foundation for future growth and feature expansion.

US Governemnt Form and Information Portal

https://formalu.com

I have developed an innovative project to streamline access to US government forms, applications, and official documents by consolidating them into a single, user-friendly platform. The archive currently houses over 300,000 files sourced from over 8,000 agencies across 23,000 locations and jurisdictions.

Users can navigate the platform to find specific documents based on geographic location, relevant topics, or desired outcomes. To foster community engagement, the platform features a Q&A board that encourages the sharing of knowledge and insights.

The system also features advanced API integrations to connect with various government data sources, ensuring that the information is accurate and up to date. The search capabilities are enhanced by artificial intelligence algorithms, which deliver tailored results to users based on their queries.

This project utilizes Ruby on Rails (RoR) for its web framework, PostgreSQL for database management, and AWS for reliable hosting and scalability. Web-scraping and data harvesting technologies ensure comprehensive coverage of available government documents, making it a unique resource for navigating the convoluted landscape of government documentation.

Legal Funding Website, Lead Generation, and Workflow Automation

https://dbekcapital.com

I designed and developed a comprehensive business project for an attorney and a legal pre-settlement funding company.

The front end serves a dual function: it operates as a lead-generation tool to attract potential clients and serves as an educational resource, providing critical information regarding pre-settlement funding options, the application process, and the associated benefits for customers. On the back end, I implemented an administrative system to automate application workflows, streamlining processes for both the company and clients. This system features seamless email and SMS communication, powered by Twilio, ensuring clients receive timely updates and information throughout their funding journey. I also integrated secure payment processing and fund disbursement systems with Stripe, ensuring efficient and trustworthy financial transactions.

I collaborated closely with the clients, guiding content creation to enhance the platform's educational components. I also provided insights into pay-per-click (PPC) marketing strategies to drive traffic and generate leads effectively.
