Solution Architecture
System design and cloud architecture on AWS and Azure, architecture reviews and technical due diligence, written up as documents your team can build from.
Solution architecture & engineering
Your technical fellow, from architecture to production.
We design the system. Then we build it. AI platforms, applications, mobile apps and the backends behind them, from first diagram to production.
What we do
Five things, done end to end
AI & LLM Systems
RAG pipelines, agentic workflows, Claude API integration, speech AI from desktop audio capture to speaker identity, document AI, and self-hosted or fine-tuned models on your own GPU infrastructure.
Applications, Mobile & Backends
Web, desktop and mobile apps with the APIs, databases and pipelines behind them, deployed securely on cloud or on-prem.
Healthcare AI
Revenue cycle automation, clinical documentation and ambient listening, medical coding support, document classification and EMR consoles.
Fractional Architect / Technical Partner
Ongoing architecture leadership for startups and teams that need senior technical direction without a full-time hire.
How we work
From first conversation to a system you run
- 01
Discover
We learn the business problem, the constraints and the systems already in place.
- 02
Architect
We design the system and write it down: architecture document, release plan, deployment guide.
- 03
Build
We build in short increments you can see and test, with automated tests and CI from the start.
- 04
Run
We deploy, monitor and hand over, with runbooks your team can operate from.

Why fello.work
A fellow, not a vendor
"fello" reads as fellow: a partner who works alongside you, from the first architecture decision to the system running in production.
The architect builds it.
The person who designs your system writes its code, so nothing is lost between the diagram and production.
We run our own product.
Fello, our business suite for Indian SMBs, is live in production. We live with our architecture decisions every day.
You own everything at handover.
Code, architecture documents, deployment guides and runbooks are yours, written so your team can run the system without us.
Tell us what you're building.
Start with a conversation about the system you need, the constraints you have and where you are today.
