Personal Finance Tracker
WIP
Tracklet
- My personal money babysitter — built because spreadsheets were judging me too hard.
- Punch in daily expenses, get weekly + monthly reports, and see exactly where the chai money went. Spoiler: it's always chai.
- Gmail integration auto-reads your transaction emails, lets you tag them with categories on the spot — don't have one? Create it right there, no excuses.
- Credit & debit card tracking built in — link expenses to your cards and watch your "available balance" humble you in real time.
- Heads up: still on a Google test account, so the Gmail magic is invite-only — ping me if you want in. The manual side is wide open, go wild.

What people I've worked with say
Real recommendations from teammates, mentors, and collaborators I've built alongside.
“Vansh is a powerhouse full stack developer. He delivered exceptional results on every project. Nothing ever slips through the cracks with him — he's always ahead of deadlines, on top of tech trends, and ready with a solution before most people see the problem. Hard working, sharp, and genuinely talented.”

Mukul BharadwajManager at GlobalLogicWorked with Vansh at a different company
“Vansh is someone you can always count on to get things done. He is hardworking, quick to learn, and approaches every challenge with a positive mindset. He consistently takes ownership of his work and is always willing to go the extra mile when needed.”

Vishal DhimanSoftware EngineerWorked with Vansh on the same team at Superfone
“I had the pleasure of working with Vansh during a hackathon where he was in his 4th year. His leadership and mentorship were outstanding. He managed our team with exceptional skill, ensuring that each member was engaged and contributing effectively. His ability to break down complex problems and explain them in simple terms made a significant difference.”

Chittanshu SinghData Science Intern @ CEATWorked with Vansh on the same team
“Vansh and I go way back — we've been college friends for the past 4 years, and I've had the privilege of working with him on all kinds of projects. The one thing that stood out from the very beginning was Vansh's sheer determination. No matter what he takes on, he approaches it with laser-sharp focus and an uncompromising attention to detail.”

Priyanshi GoyalCo-founder, ThrdCup MediaStudied together
“'Ridiculously efficient' is the phrase that comes to mind when I think about Vansh. I was senior to him in college and we were interested in the same technology field. His ability to learn and grasp things astonished me. I still miss those Sunday mornings dedicated to fixing bugs along with tea — those sittings made me realise Vansh would be a great asset to any company.”

Deepak MundhraSoftware Engineer at Celebal TechnologiesWas Vansh's mentor
“Thanks a lot bro. You are a good learner as well, quickly adapting to the situation. I wish you a great career ahead! And keep learning and keep growing!”

Maaz Ahmad KhanSoftware DeveloperWorked with Vansh on the same team at Superfone
“One thing I've always appreciated about Vansh is how he's always willing to help — I've reached out countless times with technical questions, career doubts, and learning challenges, and he's always been there. What makes him stand out is his ability to simplify complex problems and explain them clearly. Any team would benefit from someone as knowledgeable, dependable, and supportive as him.”

Still scrolling? Let's turn that curiosity into a conversation.
Come talk shop — system design debates, side projects at 2 AM, and the tech stack we all pretend not to hate. No resume. No referral pitch. Just builders being builders.
