Your integration is too complex for standard solutions. I'm the #1-ranked API Integration Specialist in the UK. I build the foundation for you to scale 100K+ requests per second. Expert-Vetted engineer, top 1% on Upwork. API Integration is what I do best but I own the entire backend + Devops 🚀 With experience at Mastercard and Vodafone, I've solved the hard integration problems: payment processor sync, real-time data pipelines, complex third-party API orchestration. I focus on building the foundation the first time correct architecture. Deep knowledge problems, solution and trade-offs.. zero technical debt and a foundation built for scale. I architect and lead enterprise-grade backend APIs at scale, mentoring cross-functional teams through complex technical decisions. I combine deep API expertise with proven leadership delivering integrations that protect revenue, reduce latency, and scale reliably. What I Do: Lead 6+ engineer teams through API design reviews, mentoring, and formal on-call rotations Design RESTful and GraphQL APIs that scale from 1K to 100,000 requests/second (protected $2M+ in revenue through uptime) Build complex system integrations: payment processors, third-party APIs, event-driven pipelines with Kafka Architect PostgreSQL databases reducing query latency by 25x (5 seconds → 200ms on production APIs) Implement Security (SOC2, GDPR compliance, OAuth, JWT, IAM) across enterprise API systems Deploy zero-downtime API infrastructure on AWS (Lambda, API Gateway, RDS) with 99.99% uptime SLAs Technologies I Specialize In: Backend: Node.js, Python, REST APIs, GraphQL, async/await patterns, API design Integrations: Third-party APIs, Kafka pipelines, webhook systems, data synchronization Databases: PostgreSQL (optimization, scaling, replication), query tuning for APIs API Infrastructure: AWS Lambda, API Gateway, SQS, load balancing, rate limiting DevOps: Docker, CI/CD pipelines, zero-downtime deployments, monitoring Leadership: API design reviews, mentoring, on-call rotation management, technical roadmap planning Proven Impact Metrics: Latency: 5 seconds → 200ms (25x improvement on critical API queries) Throughput: Built APIs handling 10K-100K requests/second Uptime: Deployed infrastructure with 99.99% SLA (zero-downtime deployments) Scale: Architected APIs supporting 1M+ daily active users Revenue Protection: Prevented outages that would have cost $2M+ through reliable API design Team Impact: Mentored 6+ engineers through API architecture; reduced incident response time by 40% Technical Decision-Making Examples: REST vs GraphQL: Chose REST for public APIs (simpler caching, better CDN support), GraphQL for internal integrations (reduced over-fetching). Improved client performance by 30%. Synchronous vs Async: Migrated payment integrations from sync to async with Kafka, reducing API latency from 5s to 200ms while handling 2x throughput. PostgreSQL Optimization: Identified N+1 queries in API endpoints costing $50K/month in compute. Optimized to save $600K annually while improving user experience. My Approach: I focus on APIs that are reliable, scalable, and maintainable. Every architectural decision endpoint design, database schema, AWS service choice is made with long-term scalability and team velocity in mind. I mentor engineers to think systematically about API trade-offs. Leadership & Mentoring: Led cross-team API design reviews ensuring consistency across 20+ endpoints Mentored junior engineers on API design patterns, PostgreSQL optimization, AWS best practices Established formal on-call rotations and incident runbooks, improving response time by 40% Championed security-first API development (SOC2, GDPR, OAuth, JWT, IAM) Let's Talk If You Need: A senior API architect to lead your backend integration transformation Technical leadership for scaling APIs from 1K to 100K requests/second PostgreSQL optimization to reduce infrastructure costs by 30%+ Complex third-party integrations (payment, CRM, data pipelines) Mentoring for your engineering team on API design and scalability Cross-team API design reviews and architectural planning My 6 Promises: 💎 Data-driven API decisions backed by impact metrics 💎 Production-ready delivery with 99.99% uptime mindset 💎 Proactive mentoring and knowledge transfer to your team 💎 Full ownership with formal on-call API support 💎 Professional, efficient execution under pressure 💎 Partnership approach focused on long-term scaling

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.
