Work

Software Developer
Sinecta
May 2022 – Present · Contract · Remote

Four years of expanding ownership across data engineering, backend development, and cloud infrastructure — from ETL pipelines and automation to full-stack product work and end-to-end responsibility for the company's cloud architecture.

Frontend Developer
Mahesa Mexico
2024 · ~6 months · Freelance · Remote

Sole developer on the company's customer-facing website — handling implementation and deployment from start to launch using PHP, JavaScript, and Tailwind CSS.

Full Stack Developer
Moving Flasht
2023 · ~1 year · Freelance · Remote

Sole developer responsible for designing and shipping the company's quoting system from scratch — replacing a fully manual, spreadsheet-based workflow with a production-ready web application backed by real route data and a structured item catalog.

Projects

AWS infrastructure architecture diagram
AWS Infrastructure Platform Overhaul
Sinecta
AWS CDKTypeScriptECSVPCIAMALBECS Service ConnectGitHub Actions

Designed and implemented a complete AWS infrastructure platform using CDK, replacing isolated EC2-based services with standardized infrastructure across dev, staging, and production.

  • Built the foundational cloud layer: VPCs, subnets, IAM roles, ECS clusters, ECR repositories, load balancers, and ACM-managed certificates.
  • Introduced isolated environments with autoscaling ECS services and private service-to-service communication using ECS Service Connect.
  • Created reusable CDK constructs to standardize infrastructure patterns across services.
  • Reduced infrastructure costs by 65% and standardized CI/CD with GitHub Actions using build-once, promote-many deployments.
Sentinel-2 NDVI output over agricultural parcels
Satellite Imagery Processing Pipeline
Sinecta
Sentinel-2RasterioPrefectECS FargatePythonS3

Rebuilt a manual SentinelHub-dependent imagery workflow into an automated Sentinel-2 processing pipeline using public COG files on S3.

  • Processed 1.5 years of historical data in ~43 seconds for new projects.
  • Reduced daily batch processing to under 30 minutes across tens of thousands of parcels.
  • Used Rasterio and matrix-based operations for spectral band extraction and index computation.
  • Orchestrated concurrent workloads with Prefect and ECS Fargate.
Freight quotation system UI
Freight Quotation System
Moving Flasht
FastAPIReflexDockerCloud RunPostgreSQLGoogle Maps API

Built a web-based freight quotation platform to replace manual Excel-based pricing and hand-calculated route estimates.

  • Reduced quote generation time from ~10 minutes to under 1 minute.
  • Automated volume estimation, labor calculation, and distance-based route pricing.
  • Integrated Google Maps API to calculate routes with and without tolls.
  • Deployed backend and frontend services with Docker on Google Cloud Run.
FIRA agricultural cost data sheet
Agricultural Cost Data Extraction Pipeline
Sinecta
BeautifulSouppydantic-aiFastAPIPostgreSQLDockerECS

Built a pipeline to extract agricultural cost benchmarks from FIRA PDF catalogs, where table layouts varied across crop cycles and broke rule-based parsers.

  • Increased coverage from ~10 PDFs per season to the full catalog — up to 70 PDFs per season.
  • Replaced brittle PDF parsing rules with an AI-assisted extraction pipeline.
  • Scraped, downloaded, parsed, validated, and stored benchmark data in PostgreSQL.
  • Exposed the processed data through a FastAPI CRUD API.
Sentinel-2 scene classification map
Sentinel-2 Cloud Detection Model
Sinecta
scikit-learnAWS SageMakerSentinel-2Python

Trained and deployed a custom pixel-level cloud detection model for Sentinel-2 imagery used in agricultural parcel analysis.

  • Achieved accurate cloud detection on ~90% of parcels.
  • Outperformed s2cloudless and Sentinel-2 SCL under real-world field conditions.
  • Integrated the model into the imagery pipeline to mask cloud-contaminated pixels before band extraction.
  • Reduced invalid readings caused by cloud-covered satellite imagery.

Milestones

2023
Electron-Phonon Coupling & Superconductivity in α-MoB₂↗
IFUAP

Co-authored a computational physics paper published in Physica Scripta (IOP Publishing) on electron-phonon coupling in α-MoB₂ under pressure — handling data extraction, computational result processing, and scientific visualization across a first-principles study.

2023
1st Place · Internal AI Hackathon
Sinecta

Won Sinecta's inaugural AI hackathon by building an LLM-powered agronomic report generator — automating analysis and interpretation of field data for agricultural producers.

2022
Scholarship · Haciendo Ciencia en la BUAP↗
BUAP

Awarded a competitive academic scholarship for a first-principles computational study of MoB₂ lattice dynamics under pressure, as part of BUAP's annual science program.

About

I'm the kind of engineer who draws the diagram before opening the editor. Infrastructure that stays predictable, code a teammate can read without a walkthrough, processes that don't break when someone's on leave — that's what I build.

Over the past four years I've worked across the full stack — REST APIs, database design, CI/CD pipelines, Prefect data flows, and AWS infrastructure with CDK — as a solo developer and on teams of five or six. Spec before code, tests before implementation, LLMs as a deliberate tool for code review, data extraction, and architectural thinking — not a shortcut. Based in Puebla, Mexico, and actively looking for my next role.
