Mohsin Hayat
Senior Software Engineer specializing in Applied AI and Backend Systems
I’m a software engineer based in Lahore, Pakistan. I build production AI and backend systems where reliable engineering matters: conversational experiences, data-intensive agents, and the services around them.
Currently at OnService.AI. I build Python services and conversational AI experiences for airline systems, including workflows for World2Fly and LASER Airlines.

What colleagues say
The best description of how I work comes from the people who have worked alongside me.
“One of those hires you notice from day one. Adapted incredibly fast, brought fresh technical perspectives, and consistently went beyond what was required.”
“Over this time he consistently proved his value as a smart, capable, autonomous and reliable software engineer.”
Independent projects
Selected work
These products best represent the kind of engineering I enjoy: practical AI, dependable backend services, and tools that solve real problems.
SnippetGraph
Independent proof of conceptI built SnippetGraph to give AI teams a more dependable way to manage the context their agents use.
Instead of leaving knowledge scattered across documents and tools, SnippetGraph lets teams compose reusable snippets into pages and publish versioned, hash-verified releases through GitHub. This makes changes reviewable, traceable, and easier to use in production AI workflows.
- GitHub GraphQL API
- versioned content
- release artifacts
FirstCustomer
Independent projectA weekend project that gives landing pages an honest first impression and practical fixes, shaped by feedback from people who tried its first version.
The current version checks 20+ website signals in milliseconds with negligible analysis cost, then uses an LLM to turn structured findings into a readable report. Five customer personas bring different perspectives to the review.
- TypeSafe AI
- structured analysis
- LLM synthesis
Zaati OS
Independent open-source projectI built Zaati OS to turn the AI tools I already use into one private place to catch up on my day.
It brings calendar, inbox, work, finances, and goals into a personal dashboard. The AI prepares the information, files keep the history, and I stay in control of the data.
- JavaScript
- file-based data
- AI tools
Professional experience
Experience across applied AI and backend engineering
Much of my professional work lives inside private company systems, so I cannot publish the code. I can, however, explain the problems I worked on and the engineering behind them.
Airline conversational systems
OnService.AI
I build Python services and conversational AI experiences for airline systems, including workflows for World2Fly and LASER Airlines.
AI for ecommerce analytics
Trafilea Tech E-commerce Group
Built a production NL-to-SQL agent across 30+ campaign-data tables and architected a hierarchical LangGraph budget copilot in the context of approximately $5M in monthly advertising spend.
Event-driven healthcare platforms
Awell Health
Owned core APIs and event-driven systems that helped scale the platform to 100K+ clinical workflows per month.
Engineering focus
Applied AI, backed by solid systems
I’m a confident, curious engineer who learns something new every day. The tools listed here reflect my experience so far, not the limits of what I can build or learn. I choose technologies to fit the problem and enjoy getting comfortable with unfamiliar systems.
Recent tools include Python, TypeScript, JavaScript, SQL, LangGraph, LangChain, Node.js, FastAPI.
Public writing
Engineering notes and career retrospectives
I occasionally write about engineering, remote work, and lessons from building an international software career from Pakistan. Some early career notes date from 2022; newer writing follows independent projects and what I am building now.
