You don't just need backend code; you need an architecture that scales effortlessly without inflating your cloud bill. With over 15,000+ hours logged and a Top Rated Plus enterprise track record, I specialize in designing, migrating, and deploying bulletproof backend systems from the ground up.
Unlike pure DevOps engineers who only manage servers, or standalone backend developers who don't understand cloud costs, I handle the entire lifecycle. Coming from a deep Full-Stack Engineering background, I architect modular business logic and then build the automated, self-healing Kubernetes clusters and CI/CD pipelines to support it safely.
Recent Architecture & Migration Wins:
• Predictive AI & IoT Healthcare (GCP): Engineered a high-velocity data pipeline using Google Pub/Sub and BigQuery to ingest millions of daily IoT sensor events. Developed a Python-based Machine Learning engine that establishes patient behavioral baselines and triggers real-time, life-saving anomaly alerts.
• Enterprise IoT & Fleet Management: Led the complete architectural redesign of a legacy PHP Symphony monolith into a highly concurrent Go (Golang) microservices ecosystem on AWS, seamlessly processing GPS telemetry from 50,000+ devices every 2 seconds.
• AWS Cost Optimization: Architected self-healing enterprise AWS environments using Terraform and Kubernetes, successfully reducing a client's monthly cloud spend by 80% while increasing system reliability and SOC2 readiness.
• Secure Healthcare & FinTech Platforms: Designed decoupled, ACID-compliant .NET Core and Python backend architectures to securely process sensitive financial transactions and HIPAA-compliant patient records with zero latency.
Core Engineering Stack:
• Backend Architecture: Go (Golang), Python (FastAPI), .NET Core (C#), RESTful APIs, Microservices Design
• Cloud Infrastructure: AWS (EKS, ECS, EC2, Lambda, RDS), GCP, Azure
• Containerization & IaC: Kubernetes, Docker, Terraform, CloudFormation
• CI/CD & Automation: GitHub Actions, GitLab CI, Jenkins, Custom Workflow Automation
I partner with SaaS, FinTech, and enterprise teams to modernize legacy backends, conduct deep infrastructure audits, and automate deployments from code to production.
If your current backend is struggling to scale, or you need to aggressively optimize your cloud spend with a modernized architecture, let's schedule a brief technical audit of your current setup. I am happy to share sanitized architecture diagrams of similar enterprise systems I have built.

I’m a backend engineer who’s been building scrapers, bots, and data pipelines for 5+ years, 3 of those on Upwork delivering full projects on my own. Most of my work is around browser automation, document extraction, and setting up systems that can scale without constant fixing.
What I do
* Playwright / Selenium automation with retries and logging
* OCR + LLM pipelines that turn huge PDFs into structured JSON
* Custom APIs and automations with FastAPI, Zapier, or n8n
Recent work
* Mortgage PDF engine: processed 200+ page files into structured JSON with confidence scores
* Dual-CAPTCHA scraper: solved math images + hidden JS to collect 1.8M records
* Ticket parser API: normalized thousands of ticket layouts into one schema, running in production
Tech
Python • FastAPI • Playwright • Selenium • AWS (Textract, Fargate, Lambda, S3, DynamoDB, EC2, ECR, ECS, ...) • Tesseract • Docker • Terraform • Postgres • MongoDB • GPT / Claude / LLaMA
I like building things that are solid, maintainable, and easy to hand off. If you need a bot, extractor, or workflow that just works, let’s talk.

Most software projects don't fail because of technology.
They fail because nobody owns the entire process.
Founders are forced to manage developers. Developers wait for decisions. Priorities change weekly. Budgets grow. Deadlines slip. The product launches months later than expected-or never launches at all.
For the last 20 years, I've helped companies bridge that gap.
I'm a Technical Project Manager, and Full-Stack Architect who leads software delivery from idea to launch and beyond. I combine technical leadership, project management, product strategy, and hands-on engineering experience to help businesses build the right product, execute efficiently, and scale with confidence.
I've successfully delivered 474+ projects for startups, agencies, and established businesses across the United States, Europe, and Latin America while maintaining a 100% Job Success Score on Upwork and generating more than $400,000 in platform earnings.
I also lead Galindo Consulting Group, one of Upwork's longest-standing Top Rated Plus agencies, with:
• 4,100+ completed projects
• $5M+ earned on Upwork
• 461,000+ hours worked
• 100% Job Success Score
• Operating successfully since 2007
When you work with me, you're not hiring a task manager or another developer. You're hiring someone who takes responsibility for outcomes.
