I freelance on focused project work where the job is to solve a real problem and ship something that works. You get someone who reads the spec properly, asks the right questions, and hands back clean code without needing to be managed. My background is enterprise software: C#/.NET, ASP.NET Core, Entity Framework, background services, and the kind of API and data work that has to survive real users and real money. I bring that same standard to freelance projects: clean architecture, sensible error handling, and no shortcuts that bite you in production. What I build: • APIs and integrations. REST API design, third-party platform integrations, OAuth, webhooks, payment and booking flows. If it needs to talk to another system reliably, that's my lane. • C#/.NET backends. ASP.NET Core services, EF Core, migrations, background jobs and scheduled workers. • Python backends and automation. FastAPI services, data pipelines, scrapers, and automation scripts. Practical Python that does a job, not a science project. • SaaS and web apps. Full-stack work with React front-ends on Python or .NET backends, including multi-tenant systems and property-management and channel-sync platforms with live third-party data. • AI integrations. Assistants and MCP servers that answer from your own database or documents instead of guessing, and AI steps inside workflows you already run, with every query logged. • Infrastructure. Docker, Ansible and OpenTofu, high-availability database clusters, CI/CD and monitoring, so the thing I build keeps running after handover. • Web automation and browser extensions. Chrome (Manifest V3) extensions and Playwright automation for sites and web apps you have access to. How I work: I scope honestly up front. If something's a bad idea, I'll tell you before you pay for it. I favour the simplest solution that solves the actual problem over the most impressive-looking one. Communication is clear and async, no daily standups required and no chasing me for updates. A good share of my clients here come back for another project. From my latest large project: "Helgi embraced every challenge and consistently delivered beyond our expectations." If you've got a backend, API, integration, or automation problem, send me the details. I'll tell you straight whether I'm the right fit, what it'll take, and how long. less -

I build...Fed up with manual workflows? I help startups and enterprises automate complex workflows and build scalable AI-powered web apps. I design and implement intelligent backend systems that integrate Large Language Models (OpenAI GPT-4, Claude, etc.), vector search (RAG), and automation agents with your stack. I build end-to-end AI Automation (document processing, CRM integration, lead scoring, automated reporting) using LLMs and Python. Create RAG search/QA systems over your proprietary data. Develop custom AI agents (with LangChain, LangGraph, CrewAI) that autonomously handle tasks. With YC-backed startup experience as a founding engineer, my Python/Django + React/Next.js solutions run at enterprise scale, processing 1M+ API calls/day and driving $50K+ ARR. I deliver results fast. I lead with transparency. You’ll see a working MVP in weeks, not months of planning. I provide clear timelines, code milestones and frequent demos. Before any contract, I’ll outline the right architecture and feasibility for you. Most importantly, if the tailored solution I deliver doesn’t meet your success criteria, I stand by a 100% money-back guarantee. Technology Stack ✔️ AI & LLM: OpenAI (GPT-4/GPT-4o), Claude AI, Mistral; LangChain/LangGraph; AI Agents and multi-agent orchestration; prompt engineering and fine-tuning; embedding models and evaluation. ✔️ RAG & Vector Search: Pinecone, FAISS, Weaviate, pgvector, Chroma; semantic search pipelines for document intelligence. ✔️ Python (Django, FastAPI, Flask); REST APIs, WebSockets; PostgreSQL: Celery & Redis ✔️ React.js, Next.js, TypeScript; UI frameworks (Bootstrap, Tailwind, MUI). ✔️ DevOps / Cloud: AWS, GCP, Docker, Kubernetes, GitHub Actions; Nginx, Cloudflare CDN; CI/CD pipelines, automated testing. ✔️ Data & Automation: Web scraping (Scrapy, BeautifulSoup), ETL pipelines, Pandas for data processing; integrations with third-party APIs/CRMs. Clients trust me to deliver results: I’ve been a founding/core engineer at YC-funded startups. My work has driven real outcomes (reduced process time, higher accuracy, revenue growth). One of my client said⭐⭐⭐⭐⭐ “I have never worked with a better freelancer. Hammad is extremely independent and keeps you updated with all progress.” I’d love to work with: ✔️ Tech Startups / SaaS Founders or teams adding AI automation or scaling their backend. ✔️ FinTech / HealthTech needing secure, compliant systems with AI-driven automation (e.g. finance tools, medical workflows). ✔️ Organisations seeking to transform manual workflows (CRM, support, analytics) with AI and automation. 📩 Contact me with your project details. I’ll honestly assess fit and outline an AI-driven solution before any commitment. Not a fit: Projects dominated by ultra-low budgets or impossible deadlines. Industries like gambling, adult content or fraud are out-of-scope. I also don’t do minute-by-minute hourly tracking; my focus is on delivering value, not punching clocks. less -
