🚀 HELPING SAAS COMPANIES, STARTUPS, AND ENTERPRISE TEAMS BUILD RESILIENT BACKEND INFRASTRUCTURE AND BULLETPROOF DATA PIPELINES Are you struggling with a sluggish backend, scaling bottlenecks, or data extraction pipelines that break the moment a site updates? When you are building a high-growth product, "just coding" isn't enough. You need an architect who understands how to build for the next 100k users without accruing technical debt. I specialize in partnering with North American and European founders to turn technical complexity into business growth. 🛠 HOW I HELP YOU SCALE High-growth companies bring me in when "good enough" is no longer an option. Here is my focus: • SEAMLESS SCALABILITY: I architect Python (FastAPI, Django) and Go environments designed for high-traffic spikes. Whether it's optimizing SQL queries or implementing Redis caching, I ensure your app stays fast under pressure. • BULLETPROOF DATA EXTRACTION: I build advanced web scraping and automation systems that reliably bypass modern bot detection (Cloudflare, Akamai). Get the market data you need without the maintenance headaches. • LEGACY REFACTORING: I help startups clean up "spaghetti code" and transition to clean, modular architectures (Microservices, Hexagonal) that are easy to maintain and test. • DEVOPS & CLOUD: Expert deployment and orchestration using AWS, Docker, and Kubernetes with robust CI/CD pipelines. 🎯 SPECIALIZED INDUSTRY EXPERIENCE • SaaS & B2B Software: Building robust APIs and multi-tenant architectures. • E-commerce & FinTech: High-volume data processing and secure integrations. • AI & Data Engineering: Pipeline automation and ETL for machine learning models. • Real Estate & Lead Gen: Massive-scale web scraping and data normalization. 💻 TECHNICAL STACK • Languages: Python (Expert), Golang, C#, Bash Scripting • Frameworks: FastAPI, Django, Flask, Celery • Data Extraction: Scrapy, Selenium, BeautifulSoup, Playwright, Appium, Puppeteer • Databases: PostgreSQL (Optimization), MongoDB, Redis, Elasticsearch • Cloud/DevOps: AWS (EC2, Lambda, S3), Docker, Kubernetes, Terraform, CI/CD • Integrations: Stripe, Twilio, Discord.py, Custom REST/GraphQL APIs, Snip API 🚀 WHY WORK WITH ME? Unlike a generalist developer, I provide senior-level oversight. I don't just write code; I design systems. • US-Client Specialization: I understand the pace, communication standards, and quality expectations of high-growth US startups. • Architecture First: I build it right the first time so you don't have to pay to build it twice. • Reliability: 6,700+ hours of proven success and a history of long-term partnerships.
