Porfolio

Experiencia laboral

Upwork

AI Integration Engineer — OpenAI Automation & Assistants

Upwork • Freelance

Jan 2026 - Jan 20260 mos

Implemented AI features that are practical and production-ready: chat assistants, knowledge-base Q&A, content generation tools, and internal automation bots. I connect OpenAI APIs to Django backends, build prompt templates, set up structured outputs, and add guardrails for safer responses. I improve reliability with logging, fallback flows, rate-limit handling, and cost control. When needed, I implement retrieval-based search (documents/FAQs) so the assistant answers using company data, not guesswork—making it useful for support, operations, and sales.

Full-Stack AI SaaS Developer

Dec 2025 - Dec 20250 mos

Built and maintained SaaS web applications end-to-end with Python/Django, Django REST Framework, and AWS. I translate business workflows into clean modules (auth, roles/permissions, subscriptions, dashboards, notifications) and design reliable REST APIs for mobile/web clients. I integrate third-party services (payments, email/SMS, analytics) and implement background jobs for automation and reporting. I focus heavily on security, database performance, and clean code structure so the system remains stable as features grow and traffic increases.

Backend Engineer — ERP/CRM & Business Systems

Aug 2025 - Sep 20251 mo

Developed business systems like CRM, inventory, billing, and reporting tools that match real company processes. I design database schemas, implement approval flows, invoice generation, customer records, audit logs, and role-based access control. I improve performance by optimizing queries, indexing, caching, and refactoring slow endpoints. I also create admin tools for support teams to manage records safely. The result is a system that reduces manual work, improves data accuracy, and gives owners visibility through clear dashboards and export-ready reports.
