Full Stack Web Dev (legal tech platform project) Karapet's team did a great job building our complicated legal tech MVP. We worked directly with a skilled software developer with a great work ethic who delivered on time in a continuous basis. Our MVP was a complicated and some iteration on building, but once aligned it was successfully built. Happy to work with Karapet and his team again, and recommend them.

Yerevan, Armenia - 4:51 am local time
I am a TOP RATED PLUS Senior Full Stack Developer with 15+ years of experience and more than 34,000 hours completed on Upwork, specializing in Python, Django, React, and scalable SaaS application development. I build modern, production-ready platforms from end to end — combining backend architecture, frontend engineering, database design, API integrations, cloud infrastructure, and DevOps into complete full stack solutions.

I work closely with startups, founders, and established businesses to transform concepts into scalable digital products. Over the years, I have delivered 85+ MVPs, SaaS platforms, internal tools, dashboards, marketplaces, and enterprise applications, helping companies validate ideas, launch faster, secure funding, and scale with confidence.

My expertise covers the full software lifecycle — from technical planning and product architecture to development, deployment, optimization, and long-term maintenance. I specialize in designing clean, modular systems with scalable backend services, responsive frontend experiences, efficient data structures, and maintainable codebases built for growth.

On the backend, I primarily work with Python, Django, Flask, FastAPI, Node.js, Express.js, and NestJS to build secure, high-performance APIs, authentication systems, business logic layers, asynchronous workflows, task queues, microservices, webhook systems, and event-driven architectures. I have extensive experience developing RESTful APIs, GraphQL endpoints, WebSocket-based real-time systems, background workers, cron jobs, and third-party integrations.

On the frontend, I build modern interfaces using React, Next.js, Vue.js, Angular, TypeScript, JavaScript ES6+, Redux, Context API, and component-based architecture. I focus on responsive design, reusable UI systems, SSR/SPA applications, accessibility, SEO optimization, frontend performance, hydration strategies, routing, and advanced state management.

My database expertise includes PostgreSQL, MySQL, MongoDB, Redis, SQLite, and ORM-based modeling. I regularly design relational schemas, optimize queries, implement caching strategies, indexing, replication, and performance tuning for large-scale applications.

I also specialize in AI-powered product development, integrating OpenAI, GPT-4, LLM workflows, vector databases, embeddings, recommendation engines, NLP pipelines, AI assistants, automated classification systems, intelligent search, and workflow automation.
