Sellerbate Amazon Customer Service Platform
Sellervate is a platform designed to help sellers manage customer communications, orders, and support conversations through a centralized hub. It helps sellers keep track of customer inquiries, messages, tickets, and order-related information in one place.
The problem it solves: Customer conversations and order information can become fragmented or inconsistent across different systems, making it difficult for sellers to manage support requests and maintain a clear history of interactions. Sellervate centralizes this information and helps synchronize data between services.
What problems I solved:
- Backend maintenance and bug fixing: Investigated and fixed backend issues, including filter-related bugs.
- Ticket synchronization: Investigated tickets that were not being synchronized correctly between the production environment and the Hub.
- Customer conversation debugging: Analyzed cases where customer conversations and tickets appeared separated or displayed different information across the Hub.
- Message synchronization: Investigated inconsistencies between messages stored in production and staging environments.
- Database cloning and migration: Cloned the production Supabase project into a new project for staging and development purposes.
- Database comparison and data reconciliation: Compared production and cloned databases to identify inconsistencies in tickets, messages, and assignments, using production as the source of truth.
- Production and staging maintenance: Investigated Supabase production Disk I/O consumption and worked on transferring production messages and statuses to staging.
- Email processing and synchronization: Investigated the configuration and behavior of email-processing and message-synchronization services.
- Environment configuration: Updated environment variables and service configurations after creating a new Supabase project.
- Infrastructure troubleshooting: Investigated how the frontend, Hub, backend APIs, database, and asynchronous processing services interact.
Incident investigation and reporting: Traced issues across multiple services, identified possible root causes, and documented findings and technical updates.

FINZAR: financial advisor platform
Full-stack web platform I designed, built, and deployed end-to-end for a financial services client. I handled the full lifecycle: client meetings, scoping, development, iterative feedback, and production deployment on a VPS.
Built with Django 6 and Python 3.12 on the backend, HTML/CSS/JavaScript and Django Templates on the frontend, and SQLite for data. Deployed with Docker and Docker Compose, served by Gunicorn and WhiteNoise behind an Nginx reverse proxy with HTTPS, and managed through environment-based configuration with automated migrations.
Key features: secure authentication with investor profiles (experience level and risk tolerance), investment opportunities listings, financial news with rich-text editing, a learning center, live quotes for stocks, crypto, bonds, and forex with personalized watchlists, and full portfolio management with transactions, holdings tracking, and automatic P&L. A customized Django Admin lets the client manage everything autonomously.
The project was delivered iteratively in close collaboration with the client — including a full visual redesign — and ships through a documented Docker workflow for stable, repeatable releases.

Minca AI — AI-Powered Insurance Underwriting Platform
Worked as a backend developer at Minca AI, a platform that automates vehicle insurance underwriting and quoting for the Mexican market, built as a microservices monorepo (Python/FastAPI, Next.js, PostgreSQL, S3).
My focus was the Quoter Service, a microservice that takes vehicle data, injects it into a formula-heavy Excel pricing workbook, runs recalculation via headless LibreOffice, and returns structured premiums and breakdowns.
Key contributions: Built a low-memory XLSX engine (ZIP-level manipulation) to process fleets of hundreds of vehicles with optimized RAM usage, developed the batch quote formatting endpoint, generating Excel files with printable and detail sheets, implemented insurance branch summaries, coverage overrides, and default values for absent coverages, built vehicle-level error detection and display in the frontend (React/Next.js), fixed LibreOffice formula recalculation issues and optimized batch sizes, memory, and S3 template caching.

GONAU: All-in-One Platform for Real-Time Delivery Optimization
Worked on a backend system built with NestJS and Supabase relational database. I implemented WebSocket connections to stream real-time user data and order status updates, allowing managers to monitor each order’s state and assignment in real time. I developed REST endpoints to retrieve and delete users, and integrated Auth0 APIs to access user data and enforce role-based access control across different endpoints. Additionally, I created duplicate user records in Auth0 and implemented logic to merge and align user data from Auth0 with data stored in Supabase to ensure consistent access management.

SwaplyAr Transaction Platform
Worked collaboratively with the data engineering team to design and develop backend endpoints using Express. I implemented endpoints to retrieve user information, delete users, add payment methods, and contributed to the authentication logic based on JSON Web Tokens (JWT). I also collaborated on the design of database tables related to users and their associated accounts, among other components.
Tech Stack
The system was fully functional and the authentication flow was operating correctly during development and deployment. At a later stage, issues were reported that appear to be related to changes or misuse on the client side, which impacted the authentication behavior. At the time of delivery, the authentication system was stable and working as expected.

BLK Market Chatbot
Web-based customer service chatbot powered by ChatGPT. I had to add functions to get real time data from the web page to answer cleint's questions and do prompt engineering to make the chatbot more accurate.
Tech Stack
The solution was fully deployed and operational in production, running on a Heroku server using Docker containers. It integrated real-time data retrieval from the web application, authentication, data processing, and external API integrations. The feature was later discontinued due to budget constraints.
