I design, build, test and deploy complete software platforms—from data architecture and backend APIs to AI integration, user interfaces, cloud deployment and automated quality assurance. My strongest technologies are Python, Django and PostgreSQL, supported by extensive JavaScript/TypeScript experience with MERN and MEAN applications. As an EU citizen, I offer convenient working-hour overlap for European and US clients. ## What I Build • AI & Generative AI: LLM applications, RAG systems, AI agents, chatbots, semantic search, structured outputs, function/tool calling, prompt engineering, model integration and evaluation. • Data Engineering: ETL/ELT pipelines, data ingestion, transformation and validation, database design, query optimization, time-series processing, IoT sensor integration and data-quality automation. • Full-Stack Systems: scalable APIs, responsive web applications, authentication, third-party integrations, background processing and real-time communication using WebSockets and SSE. • DevOps & Cloud: containerized deployment, Linux environments, CI/CD workflows, asynchronous services, production configuration and deployment automation. • QA Automation: API, integration, regression and end-to-end testing, validation scripts, test-data workflows and automated quality gates. ## Technical Stack AI: OpenAI API, Anthropic, Gemini, Hugging Face, LangChain, LlamaIndex, PyTorch, TensorFlow and scikit-learn. Vector infrastructure: FAISS, Chroma, Pinecone and pgvector. Backend & frontend: Python, Django, Django REST Framework, Falcon, Node.js, Express, React, Angular, JavaScript, TypeScript, C#/.NET and Java. Data: PostgreSQL, MongoDB, SQL Server, Redis, SQL, pandas, NumPy and SciPy. DevOps & real-time: Docker, Docker Compose, AWS S3, Heroku, Linux, Gunicorn, Celery, Redis Pub/Sub, Django Channels, WebSockets, SSE and cron. Testing: Pytest, Jest and Playwright. Integrations: Stripe, Firebase Cloud Messaging, Expo Push, OpenAI and other LLM APIs, Met.no, Meteostat and custom third-party services. ## What I Bring I take ownership from initial requirements through production deployment. I have independently built systems from zero, coordinated Android and iOS developers on API consistency, integrated complex external services and mentored junior engineers. My combined experience in backend engineering, data, AI and infrastructure enables me to solve problems across the entire platform—not just one isolated layer. I prioritize scalability, security, maintainability, clear communication and documentation, delivering systems that teams can confidently operate and extend. less -

My expertise spans mobile app development, reverse engineering, low-level C/C++, AI, full-stack development, SaaS, and cloud systems. I specialise in understanding and building software from the lowest level to the complete product — from mobile applications and native system components to APIs, databases, AI services, and cloud infrastructure. 📱 Mobile App Development I build modern, reliable mobile applications with a strong focus on performance, usability, architecture, API integration, authentication, databases, background processing, and deployment. I also work close to the native layer with C/C++, native libraries, DLLs/shared libraries, system APIs, memory management, and performance optimisation. 🔬 Reverse Engineering & Low-Level Programming Reverse engineering and low-level development are among my strongest areas. I work with C/C++, Windows internals, DLLs, EXEs, memory layouts, pointers, calling conventions, assembly, debugging, binary analysis, API interception, IPC, RPC, shared memory, and native system components. I can analyse existing software, trace execution paths, reconstruct data structures and communication mechanisms, understand undocumented interfaces, and develop compatible integrations or replacements where appropriate. 💻 Full-Stack, SaaS & Cloud I build scalable Python and JavaScript applications, REST APIs, microservices, SaaS platforms, and cloud systems using technologies such as AWS, FastAPI, Flask, Node.js, React, SQL, and NoSQL databases. 🌐 Web Scraping & Automation I develop web scraping, data extraction, automation, and data-processing systems for structured and unstructured data, integrating results into APIs, databases, dashboards, and AI pipelines. 🤖 AI & Intelligent Applications I’ve worked hands-on with practical AI applications including chatbots, trading bots, analytics, OCR, object detection, computer vision, NLP, talking avatars, and image generation. My focus is not just on building models, but on engineering AI systems that integrate into real products and deliver measurable value. ⚙️ Engineering Approach Understand the system → design the architecture → build cleanly → optimise deeply → automate wherever possible. Whether you need a mobile application, native C/C++ component, reverse-engineering solution, low-level integration, web scraper, AI application, Python service, JavaScript front end, AWS architecture, or complete SaaS platform, I bring both high-level product engineering and deep low-level technical expertise. I’m particularly comfortable with challenging projects involving existing binaries, native libraries, undocumented interfaces, legacy systems, performance-critical components, and complex technical constraints. My goal is simple: clean engineering, deep technical understanding, and software that works remarkably well in the real world. Cheers, Vishal Maharaj less -

Whether you need to connect your tools into one workflow, process documents and emails with AI, or build an assistant trained on your own data, I design and deliver the full system, from first process map to deployment. My approach is simple: understand your business process first, then build the technology around it. Not the other way around. 🤖 AI Automation & Agents Claude API, OpenAI GPT-4o, and LangChain for LLM workflows, multi-step agent pipelines, chatbots, document extraction, summarization, and RAG assistants trained on your own data. ⚙️ Workflow & Business Automation n8n, Make.com, and Power Automate for no-code and low-code workflows: lead capture and follow-up, CRM syncing, invoicing, reporting, Slack/WhatsApp/email notifications, and approval flows, all connected through APIs and webhooks. 🐍 Python Development Custom automation scripts, web scraping, data cleaning and processing, and backend services with FastAPI. When no-code tools hit their limits, I write the code that goes further. 🗄️ Data & Cloud PostgreSQL, MongoDB, Supabase, and Google Sheets as data layers. AWS, Firebase, and Docker for stable, repeatable deployment. 🌐 Web & Integrations REST APIs, WebSockets, and dashboards with Next.js and React, so your team can see and control what the automation is doing. 💳 Payments Stripe and subscription billing integrated into your products and workflows. How I work: clear milestones, fixed scope, regular updates, documented handover, and post-delivery support. You always know what is built, what is next, and what it costs. No surprises. 🍎 Background: 5+ Years in iOS Before moving into AI automation, I spent 5+ years building native Apple apps with Swift, SwiftUI, and Objective-C for iPhone, iPad, Mac, and Apple Watch, including HealthKit, Face ID, CoreData, push notifications, in-app purchases, and full App Store and TestFlight releases. I also build Flutter and React Native apps. That experience means I can add AI features to mobile apps or connect them to automated backends. Got a manual process that eats your team's time? Message me and I'll tell you honestly how it can be automated. 🚀 less -
