I help startups and SaaS teams design scalable AWS infrastructure, automate deployments, and reduce cloud costs. I’m an AWS Pro-Certified DevOps Engineer and Solutions Architect with 4+ years of experience, including delivering enterprise-grade solutions at an AWS Partner company. I’ve led 20+ cloud migrations and 25+ modernization projects — consistently achieving zero downtime and measurable performance improvements. Here’s what I can help you with: • AWS migrations (on-prem → cloud or within AWS) with zero downtime • CI/CD pipelines that accelerate releases and reduce deployment risk • Infrastructure as Code using Terraform & CloudFormation • Containerized deployments with Docker, ECS, and Kubernetes (EKS) • Cost optimization strategies that reduce cloud spend by up to 40% Beyond infrastructure, I also build production-ready backend systems using Python (Flask & Django), including REST APIs, authentication systems, and scalable database architectures — allowing me to bridge both application and infrastructure layers seamlessly. Clients typically work with me when they want: ✔ Reliable, production-grade AWS architectures ✔ Faster, automated deployments ✔ Reduced infrastructure costs without sacrificing performance ✔ A DevOps engineer who understands the full system — not just one layer If you’re looking to modernize your cloud infrastructure, improve reliability, or scale confidently on AWS — let’s talk. I typically respond within a few hours.

I fix urgent production problems: downtime, 500/502 errors, DNS/SSL failures, hacked WordPress sites, malware infections, Cloudflare misconfigurations, Magento/Shopify performance issues, failed migrations, server overload, and bot attacks. I start with a capped fixed-price diagnostic, so you know the root cause fast — without open-ended cost. Numbers first, promises second: ● $700K+ earned on Upwork, 280+ jobs, 11,900+ hours, 100% Job Success, Top Rated Plus ● Mitigated a targeted DDoS of 40M+ requests while the site stayed up for real customers ● Found and cleaned a WordPress compromise that had been quietly running for 17 months (miner + spam relay) — then hardened the stack so it can't return ● Cut a client's AWS bill by ~$500/month with one storage-lifecycle fix ● My biggest contracts run for years, not weeks: clients who hired me for an emergency and kept me for $20K–45K of ongoing infrastructure work ● Average response time: 0–4 hours ▸ EMERGENCY TROUBLESHOOTING — AWS/Linux, NGINX, PHP/MySQL, DNS, SSL, cPanel/Plesk. I diagnose across the full chain, stabilize live systems without breaking revenue paths, and explain the root cause in plain language. ▸ MALWARE REMOVAL & HACKED SITE RECOVERY — WordPress, Magento, and Linux server cleanup: webshells, backdoors, crypto miners, spam relays, SEO spam, redirect hacks. I find how they got in, remove everything (not just the visible files), fix the entry point, restore email/Google blacklist reputation, and harden so reinfection doesn't happen. ▸ CLOUDFLARE SECURITY & TRAFFIC ABUSE — WAF, DDoS mitigation, bot protection, rate limiting, Workers, Zero Trust. Scraping, carding, fake signups, login/cart/checkout abuse, API abuse. Cloudflare's defaults stop yesterday's attacks; I write the rules that stop yours. ▸ ECOMMERCE PROTECTION & CLEAN ANALYTICS — Shopify, Magento/OpenMage, WooCommerce. Bots inflating your sessions, wrecking your conversion rate, and feeding bad signals to Meta/Google? I block them at the edge — before they click your ads and pollute your pixels — and migrate analytics to Cloudflare Zaraz for clean attribution. ▸ AWS & DEVOPS — Architecture, EC2, VPC, CloudFront, RDS, ECS/Docker, migrations with zero downtime, monitoring, cost optimization, hardening. ▸ AI-ERA INFRASTRUCTURE — Deploying and securing AI workloads (agent/MCP servers, VPS automation) and defending production systems against AI-driven scraping and automated abuse. HOW I WORK: capped diagnostic first → root cause in plain language → fix with your approval → hardening so it doesn't happen again. I sign NDAs, ask only for the access I need, and document what changed. If production is on fire right now, send me the symptoms and URLs — I likely start today.

I help startups launch and scale on AWS by designing and building production ready cloud infrastructure. Whether you're building a new product or evolving an existing platform, I deploy cloud infrastructure that's designed to scale with your product. I work with modern DevOps practices to build production AWS environments, including: ➜ Infrastructure as Code (Terraform, Cloudformation, OpenTofu) ➜ Automated CI/CD pipelines (Github Actions, Gitlab, Jenkins) ➜ Containerized or serverless architectures (Docker, Kubernetes, Lambda) ➜ Secure AWS networking and IAM Setup ➜ AWS architecture design for scalable systems ➜ Production deployments using EC2, ECS/EKS, Lambda, RDS, S3, and VPC + Much more ➜ Observability, alerting, backups, disaster recovery, monitoring and performance tuning ➜ Monolith, Microservices and Eventdriven architectures supported ➜ Python, JavaScript/Typescript driven stacks, and Golang based codebases supported Once the system is built and deployed, I prefer to stay involved to keep it stable, secure, and maintainable. That includes ongoing infrastructure management, obsessive monitoring, performance tuning, finops and cost optimisation, security hardening, and incremental improvements as your product scales. ------ Thanks for reading.

🏆 18 Years in Cloud & Enterprise Tech | Currently @ AWS in GenAI Partnerships 🏆 💼 Production AI Systems Built on AWS Bedrock, Claude, n8n, OpenAI, Zapier & GHL💼 ⚡ Working Automation in Week One. Real Results in Week Two. Not a 6-Month Project 🚀 Send me an invite or message, I'll give you a free Loom audit showing exactly how I'd automate your biggest time drain. That's my promise. I help SMBs replace manual, repetitive work with AI agents and automated workflows that actually run in production. Whether you're losing revenue to missed calls, watching senior staff chase documents, or trying to make AI do real work in your business, I build systems that drive output and ROI, not slick demos that fall over in week two. Automation that performs. I build production AI and workflow systems across n8n, Make, Zapier, and AWS serverless. Proper error handling, monitoring, and a focus on the operational metrics that actually move your bottom line response times, no-show rates, conversion, revenue recovered. Architecture that scales. Most "AI automation experts" learned this stuff last year. I've spent 18 years across cloud ecosystems and currently work at AWS in GenAI partnerships. Access to the latest tools Bedrock, Kiro, Quick, Connect, Lex, Glue. Same engineering rigor, applied to WhatsApp bots, lead pipelines, and the glue code holding your stack together. Build it right, build it once. Full-stack automation. Scoping, architecture, build, deployment, handover, each stage needs different thinking. I design systems end-to-end that move work through your business, from inbound lead to qualified meeting, from missed call to recovered revenue. Data-driven delivery. I track throughput, response times, API costs, error rates, and ROI on every automation I ship. You get clear reporting showing what's working, what's not, and what we're doing about it. You own everything built code, workflows, and infrastructure. HAPPY CLIENTS: ⭐⭐⭐⭐⭐ "We were losing 30-40% of inbound leads because no one picked up after hours. Rajiv built a WhatsApp bot on n8n that responds within 90 seconds, qualifies the lead, and books them straight into our calendar. We recovered $14k in revenue in the first month alone. What impressed me most was that he set up monitoring from day one - I get a weekly report showing response times, conversion rates, and any errors. It's been running clean for four months without us touching it." - Operations Director, Allied Group, Australia ⭐⭐⭐⭐⭐ "Our onboarding process was a nightmare - consultants chasing clients for documents over email for weeks. Rajiv scoped the whole thing in one call, built an end-to-end workflow in Make that sends reminders, tracks what's outstanding, and escalates to the right person automatically. He also handed over documentation and trained our team properly. No black box. We cut onboarding time from 18 days to 4. If you want someone who builds it right and then leaves you owning it, hire this guy." - Managing Partner, Meridian Consulting, UK ⭐⭐⭐⭐⭐ "We had a pile of unstructured customer feedback across email, Intercom, and Google reviews that nobody had time to read. Rajiv built a Claude-powered classification and summarisation pipeline on AWS Bedrock and Lambda that processes everything nightly and pushes a digest into Notion. What set him apart was his AWS depth - he architected it to be genuinely cost-efficient at scale, not just a proof of concept. He also flagged three edge cases we hadn't thought of before we even started building. Would absolutely bring him back." - Head of Product, SaaS startup, Canada ⭐⭐⭐⭐⭐ "I'd tried two other automation freelancers before Rajiv. Both built things that broke within weeks and then disappeared. Rajiv rebuilt our entire outbound pipeline - Apollo enrichment, Instantly sequencing, CRM sync, the lot and it's been running without issues for six months. He tracks open rates, reply rates, and bounce rates and flagged a deliverability issue before it tanked our domain. Exactly what he promised." - Founder, Agency USA CORE SKILLS: AI Automation, AI Agents, AI Implementation, AI Agent Development, AI Chatbot, AI Bot, AI Classifier, Artificial Intelligence, Claude, ChatGPT, Gemini, OpenAI API, ChatGPT API, Anthropic, AWS Bedrock, AWS Lambda, API Gateway, EventBridge, S3, Marketing Automation, Business Process Automation, Workflow Automation, CRM Automation, Email Automation, Task Automation, Omnichannel Automation, Lead Management Automation, n8n, Zapier, Make, Python, JavaScript, Node.js, Java, Google Apps Script, JSON, API Integration, Application Integration, WhatsApp Business API, Missed Call Recovery, No-Show Reduction, Lead Response Automation, Document Collection Workflows, Interview Scheduling, Cold Outreach Infrastructure, Lead Generation, Lead Qualification, Apollo, Apify, Instantly, HubSpot, Salesforce, Pipedrive, HighLevel, Notion, Google Sheets, Data Scraping, Dashboard, DevOps, Scripting, Facebook Graph API, Architecture

Your cloud bill is not a fixed cost. It's an engineering problem - and I solve it. Most companies overpay AWS or GCP by 30-70%. The money is hiding in untagged resources, oversized nodes, idle NAT gateways, and architectures that were designed to work - not to scale economically. I find it, I fix it, and I deliver measurable ROI within the first 30 days. With $900K+ earned on Upwork, 100% Job Success Score, and 19+ years as a CTO and Cloud Architect, I bridge Engineering and Finance - translating infrastructure complexity into business impact your CFO can read. Typical Problems I Solve → AWS or GCP costs are too high and growing month over month → No visibility into what's driving cloud spend → Need a cloud infrastructure audit before scaling → AI workloads are expensive and unpredictable to run → Compliance requirements (SOC 2, GDPR, HIPAA) creating engineering debt → Architecture needs redesign for cost-efficiency before next funding round Proven Client Results ▪️ Shoebacca (Large US E-commerce) → Challenge: AWS costs exceeded budget by 40%, with no tagging, no FinOps governance, and no cost visibility. → Solution: EKS rightsizing, NAT/ALB/EBS audit, serverless Lambda migration, full FinOps governance with cost allocation tags. → Business Impact: $264,000 annual savings - AWS costs cut by 75% in one week. ▪️ US Influence Platform → Challenge: Monthly AWS bill uncontrolled, infrastructure unaudited, site latency degrading. → Solution: Infrastructure audit + Terraform migration + reserved instance strategy. → Business Impact: Monthly AWS bill reduced by 50%. Site latency improved as a bonus. ▪️ ChilliSauce (UK Event Agency) → Challenge: AWS ECS/Fargate costs growing with no optimization strategy. → Solution: Continuous FinOps management, ECS rightsizing, Fargate cost controls. → Business Impact: 30% cost reduction maintained continuously. ▪️ Datos Health (Israeli HealthTech) → Challenge: No monitoring or alerting on GCP infrastructure - production issues discovered by users. → Solution: Monitoring and alerting built from scratch with Prometheus and Grafana on GCP. → Business Impact: Zero production blind spots. Engineering team now detects issues before users do. Core Delivery Areas → Forensic Cloud Cost Audits - identify immediate 20%+ savings before writing a single line of IaC → FinOps in CI/CD - cost guardrails embedded directly in your deployment pipeline, not managed by your finance team → AI workload cost optimization - GPU orchestration, vector database cost management, LLM infrastructure efficiency → Spot/Reserved Instance Strategy & Orchestration → Serverless architectural redesign (Lambda, ECS/Fargate) for cost-efficient scaling → DevSecOps: SOC 2, GDPR, HIPAA compliance, Zero Trust architecture, IAM hardening Stack: AWS (EKS, Lambda, EC2, S3, RDS, CloudFront) · GCP · Terraform · Kubernetes · Docker · GitHub Actions · ArgoCD · Prometheus · Grafana · Datadog · Apache Kafka · PostgreSQL · AI workloads Available during US business hours (EST/PST overlap). Cloud cost optimization is the highest-ROI DevOps investment in 2026. Send an invite - I'll show you exactly where your cloud budget is leaking.
