I’m a software engineer with a strong focus on problem solving and algorithms. I’ve solved 7000+ algorithmic problems across platforms like LeetCode and Codeforces, ranking in the top 0.16% on LeetCode and achieving Candidate Master on Codeforces. My background is deeply rooted in data structures, algorithmic thinking, and writing efficient, scalable solutions under constraints. Beyond solving problems myself, I mentor students and engineers to master problem-solving skills for coding interviews and technical assessments. I focus on building strong fundamentals and recognizing patterns.

I'm a Software and AI Engineer with 5+ years of experience building full-stack systems, AI-powered applications, and production grade backend infrastructure. I specialize in Ruby on Rails, Python, Node.js, and TypeScript, with deep hands-on experience in LLM integration, NLP pipelines, computer vision, and Kubernetes based deployments. My recent work spans building humanitarian tech platforms, developing AI agents for full stack applications, and running applied ML research on Vision Transformers. I've worked with AWS, GCP, Docker, Langchain, PyTorch, and TensorFlow and I'm comfortable reviewing, validating, and extending AI-generated code responsibly. Beyond shipping code, I care about system reliability, clean architecture, and building things that hold up under real world pressure. I'm drawn to meaningful work social impact platforms, research adjacent engineering, and systems that need to actually scale. I work at the intersection of software and institutional digitalization, driving the modernization of knowledge management systems, standardizing data workflows, and translating legacy processes into scalable digital infrastructure. Strong communicator. 5-star rated. Ready to build something that matters!

I build fast, scalable web applications and backend systems that hold up in real-world usage, not just demos. My work sits at the intersection of full-stack engineering, AI integration, and DevOps, so I can take a product from idea all the way to a stable, production-ready system. Lately, I’ve been focused on building systems that combine solid engineering with automation, AI, and cloud infrastructure. 💡 What I do - Full-stack apps with clean UI, solid backend architecture, and scalable APIs - Develop AI-powered features using RAG (document processing, OCR, vector search, citation-grounded responses) - Design and optimize databases, queries, and system performance - Set up DevOps workflows (Docker, CI/CD, cloud deployment, monitoring) - Fully functional email systems like Gmail (Mailcow, SES, SMTP/IMAP, automation, deliverability, DNS setup) - Integrate third-party services (payments, auth, cloud, external APIs) 🛠 Tech stack Frontend: React, Next.js, TypeScript, Tailwind CSS, Redux, Wordpress, Elementor Backend: Node.js, Express, FastAPI, Flask Databases: PostgreSQL, MySQL, MongoDB DevOps: Docker, GitHub Actions, CI/CD, cloud deployment (AWS, Azure, Railway, Vercel, Netlify, Render) AI: RAG systems, LLM integration, vector search, OCR pipelines 🚀 How I work I focus on clean architecture, performance, and long-term scalability. With strong problem-solving skills (competitive programming), I build systems that work efficiently under the hood, not just on the surface. Clear communication, reliable delivery, and code that’s easy to maintain.

At A Glance: Algorithms

Algorithms can be developed and implemented into a wide variety of different programs, applications, and scenarios. Algorithms can be used to analyze data, predict market trends, and solve complex numerical problems. Sufficiently advanced algorithms have been introduced in recent years to develop and create automated reasoning machines and complex models for a variety of uses. If you are working with a project that could benefit from the application of advanced mathematical models for any number of uses, it becomes important to have a trained professional or consultant to help guide and interpret these algorithms and leverage them in a way that fits your needs specifically.

Algorithm professionals and consultants are highly-educated experts, often holding advanced degrees in computer science or mathematics, and depending on the degree of implementation and development you require, you may also find professionals with education and experience in a variety of the sciences. An algorithm professional is capable of building and developing an algorithm to handle a small set of instructions automatically or, in collaboration with a team of other professionals, create massively complicated, self-regulating computer software systems. Algorithm consultants can provide expertise on existing algorithms that you’ve already been using or suggestions of different modifications or customizations to optimize its use. Hiring a freelance algorithm professional or consultant on Upwork allows you to access highly specialized independent workers in a flexible and cost-effective manner while moving your project closer to implementing powerful software and numerical tools.
