Full-Stack Engineer & AI Specialist

I design and build complete web applications — frontend, backend, databases, and AI integrations. With 13+ years of experience and a live SaaS product in production, I deliver solutions that scale.

About

I don't just write code — I build products that solve real problems. Over the last decade I've evolved from frontend specialist to full-stack engineer, and recently into AI integration — shipping voice-command systems, chatbots and automation pipelines directly inside web applications.

I'm the founder of FixmanHR, a SaaS workforce-management platform I designed, built and operate solo — React frontend, Node.js/Express backend, MongoDB, deployed on AWS. Every architectural decision, every UX tradeoff and every production incident has been mine to own. That's the experience I bring to every team.

From 2017 to 2021 I co-founded QSchool, a programming school where I taught JavaScript, React and TypeScript to 100+ students. Teaching sharpens thinking. It made me a better engineer.

What sets me apart:
  • Full ownership mindset — I've built entire products end-to-end, not just features.
  • AI integration experience — chatbots, speech-to-text command systems, OpenAI & Claude APIs in production.
  • Strong architectural instincts from years leading teams and designing scalable systems.
  • React expert (8+ years) — hooks, state management, performance, component architecture.
  • Backend fluency — REST API design, Express, Mongoose, auth, file handling, deployment.

What I Build

SaaS Applications

End-to-end product development — idea to production. Auth, subscriptions, dashboards, multi-role access, billing logic.

Internal Tools

Custom admin panels, workforce management systems, reporting dashboards. Built for real teams, not demos.

AI-Powered Features

Chatbots, voice-command UIs (speech-to-text + command execution), intelligent search, and content generation integrated into web apps.

Automation Systems

Workflow automation using OpenAI and Claude APIs. Reduce manual work, increase throughput, ship faster.

AI & Innovation

AI isn't a buzzword in my work — it's a tool I use daily to deliver better products faster. I integrate LLMs and AI APIs at the feature level, not just as wrappers.

Voice Command Interface

Built a speech-to-text system that maps spoken commands to app actions — no clicks, fully hands-free, integrated into a React app.

Chatbot Systems

Designed and deployed AI chatbots using OpenAI and Claude APIs — context-aware, role-based, embedded directly into SaaS workflows.

Automation Pipelines

Connected AI models to business logic — auto-generating reports, summarising data, routing tasks intelligently.

Saurabh Bajaj

Boris has been a long time member of the team from the beginning, and develops a react based frontend from scratch for us. He has owned the end to end system from day 1, and can thrive in fast paced, early stage startup environment. He is a hard worker, and will go above and beyond to add value. He has invested in learning on areas that he never worked on before, like browser push notifications or webrtc, and successfully delivered outcomes that are running in production reliably. I am grateful for your work and wish you all the best in the future endeavors. Boris would be an asset to every team and I highly recommend that, based on our full time engagement for over 18 months.

His hard work and calm demeanor are exceptional. Good Luck always Boris you are a diamond among the others in tech.
