Enterprise Web Data Infrastructure (Scraping → Clean Data Feeds → APIs) I’m Francisco, a Computer Science Engineer and CEO at AutoScraping (Upwork Agency). When you hire me, you get me as your technical lead/POC and a delivery team behind me. We don’t just “build a scraper”; we own your web data pipeline end-to-end so your team can rely on it in production. ✅ What we handle (end-to-end) • JavaScript-heavy sites, complex navigation, logins/sessions • Anti-bot resilience: rate limits, retries, proxy/session strategy, monitoring & change handling • Data quality: schema definition, validation checks, normalization, deduplication • Delivery: CSV/JSON/Parquet, databases, data warehouses, S3/GCS, webhooks, or a documented REST API ✅ Engagement models (choose what fits) 1) DataFactory (Managed Data Feeds): we run everything; you just receive clean data on schedule. 2) DataSquad (Staff Augmentation): dedicated scraping/data engineers embedded in your team. 3) Build & Handover: production-ready code + documentation + deployment support. ✅ How we work • Quick scoping call → clear plan, risks, and success criteria • “Sample-first” delivery to validate fields and quality fast • Scale to production with predictable cadence + weekly status reporting ✅ Best fit Ideal for teams with business-critical or recurring data needs (production pipelines, larger volumes, long-term reliability). If you only need a lightweight one-time extraction, I can still help — but a managed pipeline is where we add the most value. Send: target URLs, required fields/schema, volume/frequency, and preferred delivery method — and I’ll reply with a concrete plan and next steps.

I am Atif Shahid, over the last decade, I’ve helped teams move from fragile systems to infrastructures that simply don’t break. My work sits at the intersection of cloud architecture, data reliability, and automation — designed pipelines that scale, self-heal, and stay cost-efficient. I’ve built and managed ecosystems across AWS, Azure, and Google Cloud, tuned databases like PostgreSQL, MySQL, and SQL Server to handle real-world pressure, and automated entire deployment lifecycles with Docker, Kubernetes, and CI/CD pipelines. Whether it’s modernizing legacy workloads, optimizing data layers, or orchestrating multi-cloud environments, I bring one principle to every project make it faster, cleaner, and sustainable long after deployment.

I’ve engineered environments that merge virtualization layers like VMWare, Hyper-V, and OpenStack with seamless CI/CD automation pipelines built through Jenkins, GitLab, and Terraform. 𝐎𝐧 𝐭𝐡𝐞 𝐝𝐚𝐭𝐚 𝐬𝐢𝐝𝐞, I work deeply with PostgreSQL, MySQL, SQL Server, and MongoDB, tuned queries, managed replication, and designed systems that stay consistent even under load. The scripting backbone (Python, Bash, and PowerShell) keeps everything from deployments to monitoring sharp and repeatable. 𝐌𝐲 𝐃𝐞𝐯𝐎𝐩𝐬 𝐰𝐨𝐫𝐤 revolves around designing systems that move fast without breaking. I build CI/CD pipelines through Jenkins and GitLab, automate infrastructure with Terraform and Ansible, and containerize workloads using Docker and Kubernetes.

Whether it’s cloud migration, infrastructure optimization, or orchestrating high-availability clusters, my focus is always on stability at scale. 𝐎𝐧 𝐭𝐡𝐞 𝐝𝐚𝐭𝐚𝐛𝐚𝐬𝐞 𝐬𝐢𝐝𝐞, I’ve worked extensively with Microsoft SQL Server (2012–2022) and MySQL (5.6–8.0) building, tuning, and maintaining data systems that serve as the backbone of high-traffic platforms. From T-SQL scripting and execution plan optimization to replication, log shipping, and AlwaysOn Availability Groups, I ensure performance and failover reliability stay uncompromised. 𝐌𝐲 𝐞𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞 𝐞𝐱𝐭𝐞𝐧𝐝𝐬 to stored procedures, triggers, in-memory optimization, indexing, and automated backup strategies, all designed to keep data fast, resilient, and deployment-ready. 🚫 I’m not the right fit if you’re: - Looking for a task executor instead of a system thinker. - Prioritizing speed over stability or shortcuts over structure. - Treating infrastructure as an afterthought instead of a core asset.
