This was my first interaction with Mitul and all I can say is - I definitely see a long term engagement with him.
He's very clear about his thoughts and doesn't compromise on quality, has very good experience and carries proficient expertise in AI/ML.

[CLOSED] AI agent developer
Mitul is great to work with. His main objective is to help you get what you want. My project went beyond what we had initially scoped given the ever-changing AI space. Mitul was always available for brainstorming and kind enough to accommodate requests that were reasonable. Will definitely work with him again!

I am a good fit if
- You want clear ROI, not just experimentation
- You already have operations running (team, leads, data)
- You’re ready to implement AI into real workflows
- You want results in weeks, not months
I am not fit if
- You’re exploring AI “just to try it”
- Price matters more than outcomes
- No clear use-case or business objective
- Not ready to execute fast
Why Founders and Enterprise Work With me
- I think like partners, not developers
- I focus on outcomes first, AI second
- I build systems that integrate into your business (not sit outside it)
- Fast execution with clear milestones and measurable impact
Looking to scale operations, cut manual overhead, or drive revenue through AI? Message me.
I will assess your workflow, pinpoint the highest-impact opportunities, and give you a clear build plan.
Steps for completing your project
After purchasing the project, send requirements so Mitul can start the project.
Delivery time starts when Mitul receives requirements from you.
Mitul works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement analysis with technical documentation
Requirements are analysed as soon as it comes from you. Then, I would create technical specification with architecture diagram and implementation frameworks.
Technical implementation
As soon as, technical specification verified with the client, I would start implement it by given timeline by making sure each and every requirements are implemented along with non-functional requirements.
