About
I am a software engineer with 7+ years of experience building and maintaining production applications for international clients. My core expertise is Ruby on Rails, full-stack development, and integrating AI into practical software.
I help businesses turn ideas into working products, improve existing applications, and automate repetitive processes. My work includes AI agents, MCP servers, RAG, and LLM integrations that connect models to real application data and business tools. Each one gets only the permissions it needs, and a person approves the actions that matter.
My approach is results-first: agree on the outcome, define the scope, and work toward it in small, reviewable steps. This is the idea behind Results as a Service: the work is measured by what the software achieves for you.
I use AI tools to work faster, and I review, test and take responsibility for every change that ships.
My e-commerce experience includes contributions to published apps used by merchants, catalog and order integrations, and marketplace connections. I have also built management MVPs for clients in real estate and furniture.
I am based in Lahore, Pakistan, and hold a BS-IT (Hons) degree, equivalent to 16 years of education.
To avoid mix-ups with people who have a similar name: this is Mohammad Ali Jesar (mjesar), Senior Software Engineer specializing in AI automation, based in Lahore, Pakistan, and mjesar.github.io is my official website.
