Engineering Leader

I lead an engineering team of 11 across multiple cities and manage the complete lifecycle of product initiatives, from architecture through deployment. I launched a video-based talent showcase feature integrating Android and iOS SDKs and led the migration from a monolithic backend to scalable microservices.

I manage a technology budget and reduced AWS infrastructure costs by 60% through resource optimization and configuration cleanup. I also designed real-time ETL pipelines, Elasticsearch search capabilities, optimized SQL workloads for 500GB+ datasets, and deployed PyTorch deep-learning models for audio and video profile analysis.

I built and led a distributed team of eight engineers and architected a SaaS rental platform supporting payments, authentication, geolocation, and real-time inventory management. I defined the technology stack and led delivery for more than five digital products, including an enterprise platform for Sodimac Group.

I designed microservices infrastructure handling more than two million monthly transactions with 99.9% uptime using AWS, Docker, and Kubernetes. I also integrated Stripe and PayU payment gateways, established engineering standards and code-review practices, and mentored the team through ongoing professional development.

I designed and optimized ETL pipelines for the pharmaceutical sector, enabling real-time sales-data access through a Snowflake data warehouse for Novartis. I built ingestion, transformation, and loading processes using APIs, EDI files, and database feeds.

I created automation frameworks that reduced manual data entry by 80%, improved data quality to 99.2%, and processed more than 2GB of daily data with 99.95% accuracy. I worked with business analysts, data scientists, and infrastructure teams to improve warehouse performance and support BI analytics.

I developed analytical data structures and custom scripts for major Colombian banks, improving performance and query response times. I designed Snowflake-based ETL pipelines for AVVillas Bank, consolidating data from more than six systems for credit-risk analytics and real-time reporting.

I built supervised and unsupervised machine-learning models with scikit-learn for credit-default prediction, customer segmentation, and lending analysis. The models were trained on over 500,000 historical transactions, achieved 87% prediction accuracy, and supported credit decisions for more than $100M in annual lending volume.

I led a team of seven engineers building dashboards and analytics tools for operational and workforce KPI monitoring. I managed workforce planning for more than 150 delivery agents, improving shift fill rates and reducing attrition.

I implemented Snowflake analytics infrastructure and ETL pipelines integrating HR, time-tracking, and delivery-performance data. I developed Looker and Tableau dashboards for over 50 metrics and optimized Snowflake SQL to reduce critical dashboard load times from 60 seconds to 5 seconds.

I delivered web and mobile applications across agile teams, supporting more than 15 concurrent client projects through the full software development lifecycle. I focused on reliable delivery, scalable architecture, and effective coordination among technical stakeholders.

I used Terraform and Pulumi to automate cloud and microservices deployments. I also optimized CI/CD pipelines, reducing deployment time from 45 minutes to 8 minutes and enabling more than 10 production releases per day.

I managed a team of eight engineers developing data structures and visualizations for telecommunications projects serving more than 10 million subscribers. I designed pipelines for web scraping property portals and ingested over 50,000 daily property records into a data warehouse.

I implemented real-time data ingestion for user and installation management systems, processing more than 100,000 daily events. I also optimized big-data infrastructure, reducing ETL runtime by 30% and improving data-warehouse query performance.

I led cross-country engineering teams of up to 10 engineers across Colombia, Guatemala, and Ecuador, delivering web, mobile, and value-added service solutions. I defined technology stacks for more than 20 projects based on scalability, cost, and team capabilities.

I delivered more than 15 digital products while managing annual development budgets exceeding $500K. I established technical standards, mentoring practices, and collaborative processes for distributed teams across three countries.

Specialization in data warehousing, ETL design, and machine learning applications.
