⭐️ Lead Full-Stack AI Engineer | TypeScript, Next.js, Software Architecture & Cloud I build production-grade AI and full-stack software systems — from product architecture and data design to frontend, backend, cloud infrastructure, deployment, permissions, automation, and AI workflows. My primary stack is TypeScript, React, Next.js, Node.js, PostgreSQL, and modern cloud infrastructure. I also use Python heavily for AI, data engineering, automation, ML/NLP workflows, APIs, and backend services. I’m comfortable owning both the application layer and the infrastructure layer: system design, cloud architecture, CI/CD, deployment automation, containers, databases, storage, auth, queues, secrets, monitoring, and production operations. I’m the Co-Founder & Lead Engineer of CaseOps, an AI-powered legal case management platform for law chambers. At CaseOps, I lead product and engineering across secure document ingestion, role-based collaboration, authentication, storage, hearings/order sheets, legal AI workflows, source verification, and production architecture. Before CaseOps, I worked as a Lead / Full-Stack Software Engineer for an Australian software company, building and modernising government workflow systems, public registries, and department platforms. I’m also an Upwork Top Rated Plus freelancer with 100% Job Success and $400k+ in client earnings. I’m a LUMS Computer Science graduate and the author of Practical Machine Learning, an online book covering Python, Pandas, scikit-learn, machine learning, NLP, and anomaly detection. :contentReference[oaicite:0]{index=0} ## What I’m best at ✔️ Full-stack product engineering with TypeScript, React, Next.js, Node.js, PostgreSQL, APIs, and cloud infrastructure ✔️ Software architecture for workflow systems, SaaS platforms, internal tools, dashboards, and data-heavy applications ✔️ Cloud and infrastructure engineering across AWS, GCP, Azure, and modern deployment platforms ✔️ CI/CD, containers, deployment automation, monitoring, storage, databases, secrets, and production operations ✔️ AI application development using LLMs, RAG, embeddings, structured outputs, AI agents, and workflow automation ✔️ Python for AI, data engineering, automation, ML/NLP workflows, backend APIs, scraping, and pipelines ✔️ Secure application design including authentication, role-based access control, permissions, auditability, and admin systems ✔️ Technical leadership: system design, delivery planning, code quality, client communication, and hands-on implementation ## AI, LLM & Machine Learning I build AI systems that are useful in production, not just impressive in demos. This includes: ✔️ Retrieval-Augmented Generation over documents, databases, and knowledge bases ✔️ Semantic search, vector databases, embeddings, and hybrid retrieval ✔️ AI agents and automation workflows where they genuinely improve the product ✔️ Structured outputs, tool use, prompt design, and LLM integration ✔️ Source-grounded answers, validation, evaluation, logging, and tracing ✔️ ML/NLP workflows for classification, extraction, summarization, and analysis ✔️ Cost-conscious AI architecture, including batching, model routing, and prompt optimization ## Software Architecture, Cloud & Full-Stack Development I can take a product from idea to production across the full stack and infrastructure layer. Core areas: ✔️ TypeScript, React, Next.js, Node.js ✔️ Python, Django, FastAPI, Flask ✔️ PostgreSQL, Supabase, Firebase, MongoDB, vector databases ✔️ API design, OAuth, webhooks, third-party integrations, and secure backend systems ✔️ Dashboards, admin panels, workflow tools, SaaS interfaces, and internal platforms ✔️ Cloud architecture, deployment automation, CI/CD, containers, monitoring, storage, and infrastructure operations ✔️ AWS, GCP, Azure, Docker, GitHub/GitLab CI, serverless, managed databases, and production cloud environments ## Data Engineering & Automation I also build reliable data and automation systems: ✔️ API integrations and third-party data ingestion ✔️ ETL pipelines, data cleaning, transformation, and validation ✔️ Web scraping, browser automation, and structured extraction ✔️ Reporting workflows, analytics dashboards, and operational tools ✔️ Python scripts and business process automation ## How I work I’m strongest where the project needs both architecture and execution. I can work with you on product thinking, technical planning, system design, implementation, deployment, infrastructure, and iteration. I’m comfortable owning work independently, communicating directly with stakeholders, protecting scope, and delivering production-quality software. I’m a good fit if you need a senior engineer who can design the system, build the core product, integrate AI where it makes sense, and make sure the result is secure, maintainable, scalable, and ready for real users.

Senior Backend Engineer & Architect | 3+ Years Building Secure, Scalable, Production-Ready Systems | Turning Business Ideas Into Working Software Most developers on Upwork will take your job, write the code you asked for, and disappear the moment something breaks in production. I work differently. I'm a backend engineer and SaaS architect who partners with companies that need their tech to actually hold up under real traffic — not just look good in a demo. I understand business requirements first, then use SDLC and Agile principles to break large systems into smaller, manageable components. I research before I build, suggest better approaches when I see them, and plan around real timelines and budgets. I don't just sell code — I deliver solutions that solve real problems in live production environments, and I stay accountable when things go wrong, not just when they go right. Most developers know how to copy-paste CRUD APIs. What I get hired for is the harder layer: data modeling, system design, and architecture built to survive real traffic — not something that needs a full rebuild the moment you hit scale. 🔧 What I Build For You ⚙️ Scalable Backends I build small-to-mid systems on Node.js, Express, and REST with clean monolithic architecture, and move to NestJS for larger systems that need microservices, fault tolerance, and horizontal scalability. 🏗️ Solid System Design I analyze your requirements deeply before writing a single line of code — figuring out the right stack, the right database, and the right architecture for the traffic and growth you're actually expecting. 🗄️ Data Modeling Good data modeling is the foundation on which everything else stands. I work with MySQL, PostgreSQL, and MongoDB (with Mongoose), plus Redis for caching and performance. 🚀 Production Delivery CI/CD pipelines, Docker, AWS deployment, staging environments, code review, and testing — so what ships is what actually works. 💳 Integrations & Payments Third-party APIs, webhooks, Stripe payment gateway, Stripe Connect, and marketplace payout systems. 🤖 AI Integration Feature integration using Claude and OpenAI APIs. 📦 Where I Excel Enterprise backends • Event-driven systems • Multi-tenant SaaS platforms • ERP & CRM backends • Real-time chat applications • AI-powered backends • Mobile app backends 🎯 Why a Senior Backend Developer Beats a Solo Freelancer Ownership — I stay connected through the full lifecycle and verify every feature after it's built, not before. Accountability — Version control, staging environments, code review, testing, and QA on every project. Judgment — I work honestly, understand what you actually need, and deliver that — not just what's easiest for me to build. 🛠️ Tech I Work In JavaScript, Node.js, Express.js, Next.js, MongoDB, PostgreSQL, Supabase, MySQL, Redis, AWS, Vercel, Render, WebSockets, Docker, CI/CD, Git, AI Integration (ChatGPT, Claude AI, Gemini), Stripe, JWT Authentication 📩 Free 30-Minute Requirements Review Send me your current backend setup or project scope, and I'll send back a concrete recommendation before you spend a single cent.
