Backend and infrastructure engineer, AWS is home. The thing I keep getting pulled into lately is cost, because most AWS waste hides behind stuff that works and nobody questions the service that runs fine.
I cut a production search setup 85%, Aurora at $4,200/mo down to DynamoDB plus OpenSearch around $630. Nobody had touched it in a year because it was "working." Found CloudWatch logs double-shipping at $2,766/mo because two teams set up logging and nobody checked for overlap. Found metric streams burning $1,900/mo sending everything unfiltered across regions.
That pattern got annoying enough that I built CostPatrol, an AWS cost tool with 123 detection rules across 30 AWS services that scans an account in about a minute and hands you the exact fix commands. Shipped it in two weeks.
So if your AWS bill is climbing and nobody can tell you why, that's the work I want. Connect a read-only role, I scan, and you get a ranked list of what's leaking and what it costs. No guessing.
The cost instinct comes from running production for years, not reading about it. Some of what I've built:
- Payment service for a major UK ticketing platform. Worldpay, Apple Pay, Google Pay. Real money, high volume.
- Flash sales at tens of thousands of requests a minute across 80+ venues. 100x DynamoDB throttling reduction by consolidating scheduled work.
- Uptime from 97.8% to 99.99%. The fix was ripping out a flaky CMS causing cascading failures, not adding anything.
- Deploy times from 45 minutes to under 5, across 40+ brands and 4 AWS regions. Feature rollouts from 10 minutes to 5 seconds after moving the frontend to Next.js on App Runner.
- AI chatbot on Bedrock and Claude, RAG with PII redaction, automating 80% of inquiries.
Claude Code is my primary dev tool now. I write the spec, it does the implementation, and I gate the parts that actually bite, auth, money, security, infra. Last year I shipped four production products solo this way: an AWS cost SaaS, an institutional deal-verification platform, an AI nutrition coach, and a quant trading engine. The language stopped being the hard part. What breaks at 3am, what needs a human looking at it, that's the part a model doesn't give you. So the stack is a detail. Node and Python are home, but I'll reach for whatever the job needs.
Industries I've shipped production in: fintech (KYC/AML onboarding, payments, multi-tenant auth with Cognito), wealth and investments (unit-trust onboarding, fund operations), healthcare (HIPAA, KMS, VPC isolation), ticketing and entertainment (flash-sale load, multi-region, multi-brand), legal-tech (dispute resolution, OCR, e-signatures), e-commerce, petroleum (Fortune 500 dashboards, SAP, Step Functions ETL), IoT (real-time telemetry, leak detection), and blockchain (Hyperledger identity, audit trails).
What I take on: AWS cost audits and FinOps (not only AWS, I've trimmed observability tool spend too), backend and API builds (Node, Python, GraphQL, REST), DevOps and infrastructure-as-code (Terraform, CDK, Serverless, CI/CD, multi-account), observability and alerting as code (Pulumi, New Relic, NRQL), AI and LLM work (RAG, agents, Bedrock, Comprehend, Textract, vector search), GEO and AEO optimization for AI search visibility, and architecture, breaking monoliths into event-driven microservices that hold up under load.
What I reach for most: AWS (Lambda, ECS, Fargate, DynamoDB, EventBridge, Step Functions, SQS, CloudFormation, CDK, Terraform), Node.js/TypeScript, Python, Claude/Bedrock, LangChain, FAISS, OpenSearch, PostgreSQL, Aurora, Redis, GraphQL, Stripe, Cognito, Cloudflare Workers, Pulumi, New Relic, React/Next.js.
Send over what you're dealing with, the bill that doesn't add up or the system that keeps paging someone, and I'll tell you how I'd approach it.

I build Python backend systems that hold up as they grow — designed properly from the start, so you're not rebuilding them a year later when traffic or features outpace the original setup.
Most backend problems aren't really about writing code. They come from decisions made early that get expensive later. I focus on getting those right: how the system is structured, how the data is modeled, where the bottlenecks will show up, and what to build now versus what to leave room for. That judgment is what separates a system that scales from one that gets rewritten.
What I do:
Backend & APIs — FastAPI and Django REST, built for real traffic. Versioned, well-structured APIs with proper error handling, pagination, and idempotency — not just happy-path code.
Architecture & scale — Multi-tenant SaaS systems with tenant isolation and role-based access. Structuring services and data flow so the system stays maintainable as it grows, not just on day one.
Data layer — PostgreSQL schema design, indexing, query optimization, and migrations without downtime. Redis for caching and queues.
Async & background work — Celery, event-driven workflows, webhook handling, and retries — the parts that need to keep working when external services don't.
Taking it to production — I deploy what I build: Docker, AWS/GCP, CI/CD, and monitoring. I own the system end to end, so nothing gets handed over half-finished.
When a system needs it, I also cover automation — n8n, Make, Zapier, or custom Python scripts — along with payment and third-party API integrations, so you get a complete build rather than parts to stitch together.
Why hire me:
70+ completed projects, $80K+ earned on Upwork, 5,500+ hours, and consistent 5-star reviews. Recent work includes a recruitment platform handling 50K+ requests/day, a multi-service exam platform, and multi-tenant SaaS systems running in production. The code is clean, documented, and maintainable, and I deliver on time.
If you need a senior engineer to build a backend that stays reliable long after launch — and to make the right calls while building it — message me.

🔹 Stop hiring developers. Hire someone who understands your product.
I help startups and SaaS companies build scalable backend systems, automation workflows, and data-driven platforms, the kind that don’t break after launch.
If your product involves APIs, dashboards, large datasets, integrations, or AI features, I’ve probably built it before.
What I Build Most Often
• SaaS platforms (multi-tenant architecture)
• Backend APIs (FastAPI, Django, Node.js/Express)
• Integrations (OAuth, webhooks, third-party services, CRMs)
• Automation & background workers
• Analytics dashboards & admin panels (React / Next.js)
• Data processing pipelines
• Cloud deployments on AWS
Why Clients Hire Me
Many projects fail after MVP because the backend wasn’t designed for growth.
I design for:
1. clean architecture
2. predictable scaling
3. maintainability
4. faster future features
So you don’t need to rebuild in 6 months.
Recent Work
✔ Built medical platform MVP (Node.js + React), production ready
✔ Designed military social platform infrastructure (Flask + AWS + Docker)
✔ Created organization-wide email compliance & analysis system (OAuth integrations)
✔ Built IoT monitoring platform with real-time device data ingestion
✔ Developed automation workflows & analytics dashboards
Tech Stack
1. Backend
Python (FastAPI, Django, Flask)
Node.js (Express, NestJS)
REST APIs, Webhooks, OAuth
2. Frontend
React, Next.js, Vue
Tailwind, Material UI
3. Data & Infrastructure
PostgreSQL, Redis, MongoDB
AWS, Docker, CI/CD
Large dataset processing & reporting
If you need someone who can own both the architecture and implementation, message me before hiring multiple developers.
