I provide Full Stack Developer work that outlives the launch - a Full Stack Developer who carries the Front End Developer and Backend Developer load on the same project, no vendor handoffs.
My Full Stack Developer focus is CRM, ERP, admin systems and B2B platforms - Full Stack Developer builds with RBAC, audit trails and Stripe billing. Clients come to a Full Stack Developer instead of splitting a project between a Front End Developer shop and a Backend Developer contractor, so QA and deployment stay inside one Full Stack Developer workflow. The Full Stack Developer stack is React, Next.js, Vue, PHP, Node.js, MySQL and Redis, on AWS, GCP and Heroku infrastructure sized for peak loads up to 100K users per second. Adjacent Full Stack Developer tracks: Full Stack Web Developer rebuilds, Python Full Stack Developer pairings for data work, Full Stack Developer AI on a codebase already in production, and Full Stack Developer React funnels.
My Front End Developer track is where a product stops looking like an internal tool - dashboards, admin panels, multi-tenant SaaS consoles and marketing funnels, with pages rendering in under 2 seconds. A Front End Developer React build is the default in a Full Stack Developer engagement: React with Next.js, Tailwind and Redux, plus Front End Developer Next.js server rendering when SEO carries the traffic. My Front End Developer also ships Vue 3 with Pinia when a project already runs a PHP backend. Clients searching for a Front End Web Developer or a React Developer want one Front End Developer who owns component architecture, state and API contracts. Front End Developer AI work grows every quarter: streaming responses, chat surfaces and agent panels in an app that already has users.
My Backend Developer work carries the load underneath - REST and GraphQL APIs, queues, background jobs, reporting and integrations. A Node.js Backend Developer service is the usual answer when real-time traffic or webhook throughput matters, and a Backend Developer Nest.js structure keeps a growing API navigable. On the PHP side the same Backend Developer covers Laravel and custom PHP with MySQL, Redis and OpenSearch. Where a client wants a JavaScript backend end to end, backend NodeJS services sit behind the same Next.js frontend, and a Python Developer joins for data work and AI. My Backend Developer also inherits legacy systems: a WordPress Developer migration out of Gutenberg into a custom platform, an API that keeps answering while it gets replaced.
Clients search by role, and the same engineers field all of them - a Full Stack Developer, a Backend Developer or a Software Developer on the server side, a Front End Developer, React Developer or Vue.js Developer on the client side, and PHP Developer, CRM Developer or ERP Developer profiles. When a build needs a Mobile App Developer alongside the web product, my engineers ship the app on the same Full Stack Developer API.
As COO I oversee every Full Stack Developer engagement - the discovery, matching the right Full Stack Developer engineers, the commercial side. My Front End Developer and Backend Developer engineers own the code, and they say I am full stack developer with more than 12 years of experience - my main skill is full stack development.
Clients hire me for Full Stack Developer work when they need:
- a Full Stack Developer who owns frontend, backend, infrastructure and deployment
- a Front End Developer for a dashboard, console or funnel that has to feel fast
- a Backend Developer for APIs, integrations and reporting that stay predictable under load
Recent Full Stack Developer work I shipped:
- Built a Full Stack Developer identity-verification SaaS on a PHP API with Node.js real-time on MySQL and Redis - 4K+ DAU, 1M+ checks through a public Developer API.
- Scaled a multi-currency voting SaaS to 2M+ users across 10 countries with vote locking and Stripe payouts, $2.5M+ revenue.
- Grew a B2B luxury asset marketplace with 15 engineers - React, Next.js, PostgreSQL, OpenSearch, Stripe - to 26K MAU, 75% MoM growth, 25% engagement.
- Delivered a Full Stack Developer medical-center ERP with registration, cashier, doctor and lab modules for 60 staff and 500 patients a day.
Need a Full Stack Developer who covers the Front End Developer and Backend Developer sides and stays long-term - let's talk.

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

Here’s the thing. If you’re looking for someone who understands Salesforce inside and out and knows how to make it work for your business, then I’m the right person. I’m Muhammad Umair, a Salesforce Certified Developer and Architect with over 10 years of experience. I’ve helped businesses just like yours improve their workflows, automate processes, and drive better results with Salesforce.
Let’s break it down. I specialize in Salesforce architecture consulting and Salesforce solution architecture, which means I design Salesforce systems that are built to scale and meet your exact business needs. Whether you’re looking to integrate Salesforce with third-party tools or automate processes to free up your team’s time, I’ve got the technical expertise to make it happen.
Here’s what I can do for you:
✅ Salesforce Cloud Implementations
I work with Sales Cloud, Service Cloud, Experience Cloud, and Marketing Cloud to tailor each to your specific business needs. If you want to improve your sales process, customer service, or marketing automation, I’ve got the tools to help.
✅ Custom Salesforce Development
I build Salesforce apps using Apex, Visualforce, Lightning Web Components (LWC), and Aura components. These custom solutions are designed to fit your business, solve your problems, and integrate smoothly with your existing systems.
✅ Advanced Automation & Workflows
If you’re spending too much time on manual tasks, I can help. With Salesforce automation, I’ll set up Flows, Process Builder, and Approval Processes to automate those repetitive tasks and make your team more productive.
✅ Salesforce Integrations
Whether it’s QuickBooks, Shopify, DocuSign, or any other tool, I specialize in Salesforce API integrations. I’ll connect your Salesforce platform with your other systems, ensuring your data flows smoothly and everything works together.
✅ Data Architecture & Reporting
I design Salesforce data models and create detailed reports and dashboards to give you actionable insights. The result? Better decision-making and more efficient business processes.
What this really means is that I’ll take the time to understand your unique business needs, design a solution tailored to those needs, and implement it in a way that makes your day-to-day work easier. No more wasting time on systems that don’t work for you. Just straightforward, effective solutions.
