I help startups and SaaS teams build fast, scalable web applications. If you're dealing with slow APIs, messy backend code, or need a reliable developer to build things properly from day one — I can help. 🔶SENIOR FULL-STACK SOFTWARE ENGINEER 🔶Experience: 8+ YEARS 🔶SPECIALIZATION: 🔹 Delivering enterprise-grade web applications. 🔹High-performance platforms using the MERN and MEAN stacks (Node.js, React, Angular, Express). 🔹High-concurrency backend development using GOLANG and ELIXIR (PHOENIX). 🔹Data-heavy applications that require flawless performance, real-time capabilities, and microservices architecture. With advanced capabilities in AI/ML integration and IoT, I ensure your applications are not just functional, but future-proof. I have successfully architected systems handling millions of users, focusing on complex queries, indexing, caching, and rock-solid security. CORE COMPETENCIES & SERVICES: 🔸 High-Volume Web Apps: Complete end-to-end development of Single Page Applications (SPAs) and complex web platforms using MERN and MEAN stacks. 🔸 High-Concurrency Backend Systems: Architecting highly scalable, fault-tolerant backend systems using Golang and Elixir/Erlang (OTP). 🔸 API & Integrations: Building and consuming robust RESTful and GraphQL APIs, alongside complex third-party integrations (Stripe, PayPal, Segment). 🔸 AI/ML & Data Science: Integrating Artificial Intelligence and Machine Learning models (NLP, Computer Vision, Chatbots, Big Data Analytics) directly into your web applications using Python, TensorFlow, and PyTorch. 🔸 Architecture & DevOps: Implementing CI/CD pipelines, Docker, Kubernetes, AWS infrastructure, and IoT Core backends (via MQTT). 🔸 Team Leadership: Capable of working independently, integrating seamlessly into existing teams, or leading and managing a development team for your project. TECHNICAL STACK: 🔹 Front-End: JavaScript, TypeScript, React.js, Angular.js, Vue.js, HTML5, CSS3, Tailwind CSS, Bootstrap. 🔹 Back-End (Primary): Node.js, Express.js. 🔹 Back-End (High-Concurrency): Golang, Elixir (Phoenix, Ecto, Absinthe). 🔹 Databases: PostgreSQL, MongoDB, MySQL, Redis. 🔹 AI / Data Science: Python, TensorFlow, PyTorch, Pandas, Scikit-Learn. 🔹 Infrastructure & Tools: AWS, Docker, Kubernetes, Git, CI/CD, OAuth 2.0, WebSockets. CLIENT-FRIENDLY PRACTICES I GUARANTEE: 🔸 Open Communication: I prioritize frequent updates, prompt responses, and transparent progress reports. 🔸 Strict Confidentiality: fully willing to sign an NDA before we begin discussions. 🔸 Total Ownership: All deliverables, source code, and related assets belong exclusively to you from day one. 🔸 Clean, Maintainable Code: I adhere strictly to TDD (Test-Driven Development), common design patterns, and industry best practices to ensure your codebase is scalable and easy to maintain long after the project ends. I am an excellent fit if you lack technical expertise and need a developer who can take full ownership of the architecture, or if you are simply tired of sifting through inexperienced developers and want it done right the first time. MY DEVELOPMENT PROCESS To ensure a seamless, stress-free experience, I follow a strict, battle-tested workflow for every project: 1. Architecture & Discovery: Before writing a single line of code, we define the exact scope, map out the database schema (PostgreSQL/MongoDB), and select the optimal stack (MERN, Golang, or Elixir) tailored strictly to your scalability needs. 2. Agile Execution: You will never be left in the dark. I provide transparent updates through agile sprints, so you always know exactly what is being built and tested. 3. Robust QA & Automated Testing: I heavily utilize Test-Driven Development (TDD) and CI/CD pipelines. This ensures every new feature is rigorously tested and deployed without breaking your existing system. FREQUENTLY ASKED QUESTIONS 🔹Can you rescue or optimize an existing codebase? Absolutely. 🔹How do we handle timezone differences? I maintain flexible working hours, deliberately overlapping with your timezone to ensure we have windows for real-time communication.
