BarhtaFit
A fitness platform that grew from a side experiment called “Workout Web” into a full product — workout planning, session logging and progress tracking, built with a product mindset from day one.


hello@marwankhan.dev
Full-Stack Developer & AI/ML Builder
I build practical web applications and explore AI to turn ideas into useful products — scoped cleanly, architected properly, and shipped to production.
I'm Marwan — a developer who cares less about tutorial trophies and more about working software. My focus is simple: build real products, learn through the process, and push one level further with every release.
I started with the fundamentals of the web, went deep on React, Next.js and TypeScript, and now design production-grade applications end-to-end. Lately, I'm expanding into AI and machine learning — with one goal: products that don't just work, but get smarter.
End-to-end web apps — from database schema to deployed, polished frontends.
Studying ML fundamentals with Python, moving from theory to trained models.
Not tutorials — actual products with users, deployments and iterations.
Every skill on this site was earned by shipping something with it.
HTML, CSS, JavaScript — understanding how the web actually works.
React, Next.js, Node and databases — wiring complete systems together.
BarhtaFit live in production; a CRM architected like a real SaaS.
Currently here — ML fundamentals, Python, first trained models.
Next — intelligence built into the products I already ship.
Every tool here was learned in the field — inside real codebases, real deployments and real deadlines. Dots mark what runs my production projects daily.
Interfaces people enjoy using
Systems that hold up in production
Ship early, ship often
The current obsession — growing fast
Each one starts with a real problem, gets architected like a product, and ends up deployed — not sitting in a private repo.

No inflated titles, no fake years of experience. Just a clear trajectory — and every step backed by something that actually shipped or got learned.
Started from zero: HTML, CSS and JavaScript — building pages, breaking layouts, learning how the browser thinks.
Went end-to-end: React and Next.js on the front, Node and databases on the back, wired together with APIs and auth.
Moved from 'it works locally' to 'it works for users'. BarhtaFit is live, with workout planning, session logging and progress tracking available to real users.
Deep in ML fundamentals right now: Python, NumPy and pandas for data work, then models — regression, classification, evaluation, iteration.
The destination: intelligent features inside real products. Recommendation, prediction and vision — applied, not just studied.
Full-stack development taught me how to turn ideas into products. AI is the next multiplier — so I'm going deep on machine learning, NLP and computer vision, with the same philosophy as always: learn it by building something with it.
The first target is already chosen — bringing intelligent, adaptive experiences into BarhtaFit. Software that learns from its users.
Foundations first — supervised learning, evaluation, and real datasets over hype.
Language as an interface — text intelligence inside everyday software.
From pixels to predictions — the layer behind smarter fitness experiences.
The endgame: shipping models as features people actually use.
“I don't want to just use AI APIs. I want to build products that learn.”
I'm interested in building useful products, working on challenging software, and collaborating on interesting ideas. If it ships and matters — I want to hear about it.
