Hire the Best REST API Developers
in the United Kingdom

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

Your AI integrations aren't working. Your automation is fragile. Your codebase makes new devs quit. I fix that usually in weeks, not months. What I actually deliver: - 𝑨𝑷𝑰𝒔 𝒕𝒉𝒂𝒕 𝒔𝒄𝒂𝒍𝒆: 𝒉𝒂𝒏𝒅𝒍𝒆𝒅 50𝑲+ 𝒅𝒂𝒊𝒍𝒚 𝒓𝒆𝒒𝒖𝒆𝒔𝒕𝒔 𝒘𝒊𝒕𝒉𝒐𝒖𝒕 𝒃𝒓𝒆𝒂𝒌𝒊𝒏𝒈 - 𝑨𝒖𝒕𝒐𝒎𝒂𝒕𝒊𝒐𝒏 𝒕𝒉𝒂𝒕 𝒔𝒕𝒊𝒄𝒌𝒔: 𝒔𝒂𝒗𝒆𝒅 𝒕𝒆𝒂𝒎𝒔 15-20 𝒉𝒐𝒖𝒓𝒔 𝒘𝒆𝒆𝒌𝒍𝒚 𝒘𝒊𝒕𝒉 𝒏8𝒏 𝒘𝒐𝒓𝒌𝒇𝒍𝒐𝒘𝒔 - 𝑪𝒐𝒅𝒆 𝒕𝒉𝒂𝒕 𝒂𝒏𝒐𝒕𝒉𝒆𝒓 𝒅𝒆𝒗𝒆𝒍𝒐𝒑𝒆𝒓 𝒄𝒂𝒏 𝒆𝒙𝒕𝒆𝒏𝒅 𝒘𝒊𝒕𝒉𝒐𝒖𝒕 𝒃𝒓𝒆𝒂𝒌𝒊𝒏𝒈 𝒆𝒗𝒆𝒓𝒚𝒕𝒉𝒊𝒏𝒈 - 𝑨𝑰 𝒔𝒚𝒔𝒕𝒆𝒎𝒔 𝒕𝒉𝒂𝒕 𝒘𝒐𝒓𝒌 (𝒏𝒐𝒕 𝒋𝒖𝒔𝒕 "𝒊𝒏𝒕𝒆𝒈𝒓𝒂𝒕𝒆𝒅"): reduced manual work by 60-70% for clients. Built AI-powered reception systems handling inbound calls, routing, and automated responses. Why I'm different: I don't just write code. I take ownership of your actual problem. If your LLM integration is failing, I diagnose it. If your data pipeline is bottlenecked, I optimize it. If your codebase is a mess, I refactor it so it's maintainable not just "working." Stack I know: 𝐏𝐲𝐭𝐡𝐨𝐧 (𝐃𝐣𝐚𝐧𝐠𝐨, 𝐅𝐚𝐬𝐭𝐀𝐏𝐈, 𝐅𝐥𝐚𝐬𝐤) | 𝐑𝐞𝐚𝐜𝐭, 𝐍𝐞𝐱𝐭.𝐣𝐬 | 𝐏𝐨𝐬𝐭𝐠𝐫𝐞𝐒𝐐𝐋, 𝐌𝐨𝐧𝐠𝐨𝐃𝐁 | 𝐀𝐖𝐒 | 𝐃𝐨𝐜𝐤𝐞𝐫 | 𝐧8𝐧 | 𝐎𝐩𝐞𝐧𝐀𝐈, 𝐋𝐚𝐧𝐠𝐂𝐡𝐚𝐢𝐧, 𝐂𝐥𝐚𝐮𝐝𝐞 Best for: - AI/LLM integrations that actually work - Full-stack apps from 0→1 - Fixing broken automation systems - Legacy code that needs modernization - Custom integrations (Stripe, Twilio, APIs) My approach: I respond in 2 hours. No fluff, no delays. You get working code, not promises.

$700K+ delivered on Upwork across 145 projects with a 100% Job Success Score. I architect and ship production AI systems, Voice AI agents handling live calls under 2-second latency, computer vision platforms processing 8M+ daily events, and full-stack products running in production for years. What I build: 𝗩𝗼𝗶𝗰𝗲 𝗔𝗜 & 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗔𝗴𝗲𝗻𝘁𝘀 Real-time voice pipelines combining speech-to-text, LLM reasoning, and natural voice synthesis. I built SloanConnect, an AI telephony platform that automates insurance verification calls end-to-end, navigates IVR systems, holds dynamic conversations with representatives, and scales to hundreds of concurrent calls. Sub-2-second response time, encrypted compliance handling, production-stable. 𝗖𝗼𝗺𝗽𝘂𝘁𝗲𝗿 𝗩𝗶𝘀𝗶𝗼𝗻 𝗮𝘁 𝗦𝗰𝗮𝗹𝗲 Lead AI Engineer on two production CV platforms: Adlytic - privacy-safe in-store retail analytics with GDPR-compliant pipelines, heatmaps, and POS integration, and SportsEye - real-time soccer analytics from broadcast feeds with 96% accuracy across player tracking, field mapping, and tactical metrics with zero on-field hardware. 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Hybrid recommendation engines on PySpark processing 8M+ daily impressions. NLP and sentiment systems wired into live dashboards. Healthcare process automation with HIPAA-aligned data handling. Models built to live in real environments, not notebooks. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗟𝗟𝗠 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 (𝗖𝗹𝗮𝘂𝗱𝗲, 𝗢𝗽𝗲𝗻𝗔𝗜, 𝗺𝘂𝗹𝘁𝗶-𝗺𝗼𝗱𝗲𝗹) End-to-end AI agents shipped to production: a Shopify + Amazon SP-API customer service agent with order lookup, refunds, returnless-refund policies, Slack/Email approval gates, and Klaviyo sync. Multi-step LLM pipelines with tool use, RAG, function calling, and human-in-the-loop checkpoints. I design these as systems, not single prompts, and I'm comfortable across Claude, OpenAI, and open-weight models depending on what fits the workload. 𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks. If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.
