    Full-Stack Engineer public Remote experience

    Dec 2025 - Current (8 months)
    As a Full-Stack Engineer, I built a multi-tenant SG-SST SaaS platform aligned with Colombian regulations (PHVA cycle, minimum standards), enabling company onboarding, diagnostics, weighted compliance scoring, and evidence management. I developed backend services using NestJS, Prisma, PostgreSQL, and Redis, implementing JWT authentication (access/refresh), role-based access control, and tenant-level data isolation. Additionally, I implemented a Next.js dashboard (App Router) with protected routes, session recovery via /users/me, and a reusable API client with automatic token refresh. I designed a hierarchical standards model (PHVA → parent standards → child standards → items → evidence templates → evidence documents) that supported weighted

    Aug 2025 - Current (1 year)
    At Red Valley, I contributed to VIP Clinical Group in the development and optimization of automated data pipelines integrating multiple cloud technologies. My work focused on building scalable ETL workflows that connected AWS services (Lambda, S3, Glue) with Snowflake for advanced data storage and analytics. I was responsible for designing and orchestrating serverless processes that automated data ingestion, transformation, and reporting — significantly improving reliability and reducing manual intervention. Using AWS Lambda functions, I implemented event-driven logic for data synchronization between S3 buckets and Snowflake warehouses, while leveraging Glue Jobs and Python-based transformations to ensure clean, structured datasets ready fo

    AI Model Attempter
    Outlier
    Aug 2024 - Current (2 years)
    As an Attempter at Outlier, I have participated in the evaluation and improvement of large-scale language models, focusing on refining AI-generated responses through reinforcement learning with human feedback (RLHF). This work involves analyzing, rating, and providing detailed feedback on model responses based on their accuracy, coherence, contextual relevance, and alignment with the needs of different clients and use cases. Additionally, I utilized Scala to read, review, and validate code snippets related to data processing and ETL, such as Spark-style logic, which allowed me to assess correctness, edge cases, and performance implications. While my primary responsibilities did not center on Scala development, this skill was instrumental in

    RLHF Programming Specialist
    Gi Inc
    Apr 2024 - Nov 2024 (8 months)
    As an RLHF Programming Specialist, I improved SQL, Python, and JavaScript queries using RLHF techniques by identifying and correcting structural errors. I designed and created complex SQL debugging prompts for AI model training and evaluation, while also providing constructive feedback to optimize SQL, Python, and JavaScript queries, enhancing efficiency and accuracy. Additionally, I utilized TypeScript to build and maintain tooling that supported the RLHF workflow, including internal web utilities and scripts for data labeling and evaluation, as well as API integrations. This integration of TypeScript significantly improved the reliability, consistency, and speed of the RLHF pipeline, further contributing to the overall success of our proj

    Full-stack developer
    Apr 2020 - Jul 2023 (3 years 4 months)
    As a Full-Stack Developer, I led the end-to-end migration and modernization of our platform, transitioning from a legacy stack to a RESTful service layer on top of a normalized MySQL database with cloud object storage for assets. I redesigned the data model, introduced strict validation and versioned APIs, and set up secure authentication/authorization to improve data integrity and maintainability. On the front end, I rebuilt the application in React, implementing routing, code-splitting, and caching to enhance performance and responsiveness, while also incorporating SEO-friendly practices such as meta tags, structured data, and accessible components. I wired the React app to the new API ecosystem with clean data flows and reusable hooks/se
