Hi, I'm Elias, founder of Reupped Technologies LLC. Most software projects don't fail because of poor development—they fail because the wrong problems are solved first. That's why every project begins by understanding your business, your users, and the workflow behind the idea before writing a single line of code. For more than 20 years, I've helped startups, entrepreneurs, and established businesses build software that is reliable, scalable, and designed to grow with them. Whether it's a SaaS platform, AI-powered application, mobile app, marketplace, ERP, CRM, fintech product, or custom business system, my focus is always the same: build software that solves real problems while keeping future growth in mind. I handle the complete development process, including: • Product planning • UI/UX • Web development • Mobile apps • Backend architecture • API integrations • AI solutions • Blockchain • Cloud deployment • Long-term support What clients appreciate most isn't just our technical expertise—it's our ability to simplify complex ideas, ask the right questions, and recommend solutions that make sense for the business. If you're looking for a development partner who values communication, thoughtful planning, and long-term success just as much as clean code, I'd be happy to discuss your project. less -

I build Python scrapers, Apify Actors and automation pipelines that deliver clean data on schedule, and I can host and maintain everything for you so you only receive the results. 170+ five-star reviews, 100% completion, 100% on-time and on-budget, Preferred Freelancer. Most scrapers break within weeks. Mine are built to survive anti-bot systems, resume after crashes, and keep running months after delivery. ★ FULLY MANAGED SCRAPING: YOU GET ONLY THE DATA I host the scraper, handle proxies and anti-bot changes, monitor every run, and fix it when a target site changes. Data lands in your email, Google Sheet, database or API on your schedule (daily, weekly, real-time). No servers, no proxy bills, no debugging on your side. ► Web Scraping & Data Extraction Playwright, Selenium, Scrapy, BeautifulSoup and API reverse-engineering. JavaScript-heavy sites, infinite scroll, login walls, Cloudflare, CAPTCHAs, rate limits and millions of records. E-commerce, real estate, car listings, directories, marketplaces, job boards. Output in CSV, Excel, JSON, Google Sheets or straight into PostgreSQL / MySQL. ► Apify Actor Development Production Python Actors with clean input schemas, proxy and session rotation, migration-safe state for long runs, and Store-ready monetisation. I publish my own Actors, so I know the platform from both sides. Existing Actor fixed, sped up, or converted from a plain script: routine work. ► Price Monitoring & Competitor Tracking Scheduled price, stock and listing trackers with change alerts and history, so you see market moves the day they happen. ► AI Data Extraction & Agents LLM-powered extraction, classification and enrichment. AI agents that turn messy, unstructured pages into structured, validated data. ► B2B Lead Generation Verified decision-maker contacts (CEO, CFO, founders), business email finding and verification, deliverability-checked lists ready for outreach. ► Automation, Telegram Bots & APIs End-to-end pipelines with Python, n8n and scheduled cloud jobs. Telegram bots, alerts, reports, and REST / GraphQL integrations connecting your tools. Why clients rehire me: ✅ Production-grade code: error handling, retries, logging, documentation ✅ 100% on-time across 170+ projects ✅ Clear updates without you chasing me ✅ Optional managed plan: hosting, proxies, monitoring and fixes included ✅ Support when a target site changes its layout Send me your target website or dataset. Within a few hours I will tell you if it is scrapable, how long it takes, and the cost. 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 -
