We specialize in projects where multiple technologies must work together seamlessly — software with hardware, cloud with automation, and logic with real-world operational constraints. Our work is driven by solid architecture, clean implementation, and solutions designed for long-term use, stability, and growth. 🔧 Core Capabilities Systems & Full-Stack Development End-to-end design and development of web platforms, backend services, APIs, dashboards, and mobile applications, built for scalability, security, and maintainability. Cloud, DevOps & Infrastructure Architecture and operations across AWS, Azure, and Google Cloud, including CI/CD pipelines, deployments, monitoring, performance optimization, and production hardening. Automation & Integrations Custom automation, workflow optimization, system integrations, bots, and backend processes to reduce manual work and improve operational reliability. Embedded Systems & Industrial Automation Development and integration of embedded systems, IoT devices, electronics, PCBs, PLCs, SCADA, and hardware–software interfaces for industrial and automation use cases. AI & Data-Driven Features Practical AI and machine-learning integrations such as computer vision, OCR, analytics, and intelligent system enhancements — applied where they deliver real, measurable value. Specialized & Custom Solutions Blockchain systems, trading tools, telephony platforms, and other domain-specific solutions when projects require deeper technical customization. 👥 Team & Delivery Model For larger or time-critical projects, I work with a small, trusted technical team, while personally managing and reviewing all work. This ensures clear communication, consistent quality, and a single point of accountability for the client. 🤝 Post-Delivery Support Delivery does not end at handover. We provide clear documentation, support, fixes, and ongoing assistance when required, ensuring systems remain stable, understandable, and easy to maintain over time. Our approach is reflected in consistent positive feedback from previous clients, who value technical ownership, clear communication, and dependable delivery. If you’re looking for a technical partner who thinks long-term and takes responsibility beyond launch, Rashid Tech Solutions is ready to support your project. weniger

My core focus is designing, building, and deploying AI-driven systems—from LLM-powered agents and voice assistants to data-aware automation pipelines that integrate seamlessly with production applications. I work extensively with large language models (LLMs), retrieval-augmented generation (RAG), vector databases, embeddings, tool-calling frameworks, and agent orchestration patterns to create systems that reason, act, and scale reliably. On the backend, I build high-performance APIs and services using FastAPI, Flask, Node.js, and Django, with strong experience in async architectures, background workers, and event-driven systems. I regularly work with PostgreSQL, MySQL, Redis, MongoDB, and Neo4j, and design robust data layers using SQLAlchemy, Prisma, and ORM/DAO patterns. For AI workloads, I integrate OpenAI, Anthropic, Ollama, ElevenLabs, and custom inference pipelines, alongside Qdrant, Pinecone, FAISS, and hybrid search setups. On the frontend, I build modern, scalable interfaces using React, Next.js, Vite, Tailwind CSS, and TypeScript, with a strong emphasis on UX for AI-powered tools (real-time streaming, agent state visualization, conversation flows, and admin dashboards). For mobile, I work with React Native and cross-platform architectures to bring AI features directly into user-facing apps. Automation is a major part of my work. I design end-to-end business automation systems using Make.com, n8n, webhooks, cron jobs, message queues, and direct API integrations. This includes automating CRM workflows, email systems, call routing, lead qualification, reporting, and data synchronization across platforms like Twilio, Slack, Google Sheets, Stripe, Shopify, and internal tools. I’m highly experienced in AI voice agents and real-time systems, integrating Twilio, speech-to-text (STT), text-to-speech (TTS), streaming APIs, and conversational state management to build production-ready voice and chat agents. I also work on computer-vision and multimodal pipelines, combining vision models, tracking, and sensor data for advanced use cases. From an infrastructure and MLOps perspective, I deploy and scale systems using Docker, Linux servers, cloud VPS, CI/CD pipelines, and GPU-accelerated environments. I care deeply about observability, logging, error handling, security, and cost optimization in AI systems. Above all, I love turning business problems into automated, intelligent systems—reducing operational friction, increasing efficiency, and building products where AI is not a feature, but a core capability. If you need AI agents, automation pipelines, or full-stack systems that actually work in production, that’s exactly what I build. weniger
