Hire the Best Algorithms Engineers
in Venezuela

I help B2B enterprises and technical founders transition from manual workflows and theoretical AI models to production-ready, autonomous systems. As a Senior AI/ML Engineer, my focus is on system reliability and operational efficiency. At Lazza Capital, I architected the core AI infrastructure for financial environments. I engineered Deep Learning models for fraud detection and deployed persistent-memory agent swarms. I do not build fragile chatbots. I build robust predictive analytics models, computer vision pipelines, and data architectures that execute decisions correctly and reduce your operational costs. ▶ WHAT I DO IN PRACTICE ◀ ✔️ Predictive Analytics & ML: Building machine learning models for anomaly detection, forecasting, and decision logic. This eliminates guesswork and optimizes your corporate data. ✔️ Multi-Agent Orchestration: Deploying autonomous AI swarms using LLMs and RAG architectures. This automates complex business workflows and scales your operations without increasing headcount. ✔️ Computer Vision: Engineering edge pipelines, object tracking, and image processing systems. This extracts structured data from physical environments with zero latency. ✔️ MLOps & Infrastructure: Deploying secure CI/CD pipelines, Docker containers, and cloud architecture. This guarantees high availability and scalability for your production models. ✔️ Data Engineering: Structuring data ingestion and building vector databases. This grounds AI models strictly in your private enterprise data to prevent hallucinations. 💻 TECH STACK & PLATFORMS • Languages: Python (Pandas, NumPy, Scikit-Learn), C++ • AI & ML Models: PyTorch, TensorFlow, OpenCV, XGBoost • LLMs & Orchestration: LangGraph, Claude Code, OpenAI APIs, RAG • Infrastructure & Data: Docker, AWS, PostgreSQL, Pinecone (Vector DBs) 💡 MY PHILOSOPHY Enterprise software environments are complex and cost-driven. Exceptional value lies in execution precision and strict system stability. I focus on delivering results-driven infrastructure, not opaque research experiments. If you need to scale your autonomous workflows, validate a predictive model, or deploy a secure AI architecture, send me a message. Let’s build something robust.

High-Performance Quant Developer | Python-to-Rust Migration & Hybrid Systems I build autonomous financial systems where speed meets intelligence. I specialize in developing high-frequency trading (HFT) infrastructure and migrating performance-critical Python applications to Rust to achieve massive gains in execution speed and reliability. My core strength is architecting Hybrid Systems: I use Python for rapid AI model prototyping and Rust for the high-performance execution server. By leveraging advanced APIs and bindings (like PyO3 and gRPC), I create seamless integrations that offer the best of both worlds: the flexibility of AI and the raw speed of bare-metal code. What I bring to your project: Python to Rust Migration: I port bottlenecked Python code to Rust, delivering up to 100x faster execution and eliminating GIL constraints. Hybrid AI Servers: Architecting advanced systems that run complex Autonomous Agents where the heavy lifting and data ingestion are handled by Rust servers, exposed via high-speed APIs. Autonomous Trading Agents: Development of self-evolving systems at Gptrader that adapt to market regimes in real-time. High-Concurrency Infrastructure: Building mission-critical engines using Rust (Tokio/Actix) for ultra-low latency and asynchronous data processing. Custom Backtesting Engines: High-fidelity Rust simulations capable of processing years of tick data in seconds. My Tech Stack: Languages: Rust (Advanced: PyO3, Tokio, Actix, Serde) & Python (Asyncio, PyTorch, Pandas). Architecture: Hybrid APIs, gRPC, WebSockets, Microservices. Database: PostgreSQL, TimescaleDB, Redis. If your current system is struggling with latency or memory limits, I can re-engineer your infrastructure to give you a definitive competitive edge. Let’s discuss how to take your trading performance to the next level.

I am BS in Electrical Engineering graduated with honors. During my university career I specialized in the design and development of several tools for data processing, feature & pattern extraction, time-frequency analysis, signal convolution (see my portfolio), image classification, linear & nonlinear filtering of time sequences (1D), images (2D), hyper & multi spectral images (3D) as well as the implementation of genetic algorithms for the optimization of Objective Functions subject to linear and nonlinear constraints. In my degree project I implemented a land cover classifier for satellite images (hyper spectrals) using Sparse Signal Representation as an artificial intelligence method positioned in the state-of-the-art (see my portfolio). I currently have more than 3 years of experience in applications that enable extreme performance & accuracy improvements in Machine Learning and in the powerful field of Data Science. In particular, I have heavy expertise implementing models based on classical techniques such as: Binomial and Generalized Logistic Regression, Robust Regression, Neural Networks, Vector Support Machines, K-Nearest Neighbor as well as innovative techniques positioned in the state-of-the-art as Sparse Signal Representation, all of them in applications of Image classification, Denoising, Super Resolution, among others. I have heavy skills in Python and MATLAB (with experience in R as well) so I have used these powerful programming languages for the quickly, reliable and efficient development of my projects. I also carried out 3 masters courses in Biomedical Engineering of Mathematical Methods and Statistics applied to the Engineering, with which I have solid bases to analyze and infer well on the results obtained.
