vol. 01·friday, jul 17, 2026·hyderabad ist12 projects 7 in the writing log 9 years
an honest log ofthings (A)I've built
& learned the hard way
byTapan Meena·senior supervisor of artificial intelligence
I build scalable backends, developer tools, and the occasional Raspberry-Pi trading bot out of Hyderabad — lately with help from my artificial friends. They autocomplete; I take the blame. This is where I keep the receipts — every project, every writeup, every cursed lesson — in one running log.

fig. 0portrait of the author
I'm a senior software engineer with 7 years of shipping production code — currently leading cross-functional teams atMAQ Software, mostly in the .NET andAzure world. I care about clean architecture, fast feedback loops, and dragging junior devs through the same mistakes I once made (with fewer scars this time).
Outside of work, I build small things that scratch a personal itch — a CLI to kill a daily portal click, a fintech bot living on a Raspberry Pi, an OCR overlay for macOS — and write down what broke so I don't relearn it next year.

Multi-broker auth: TOTP, OAuth, and token persistence done right
fintechHow StalkMarket abstracts four Indian broker APIs (Angel One, Upstox, Zerodha, Groww) behind one provider interface — with TOTP, OAuth token injection, persisted tokens, proactive refresh, and a 401 retry path.

Teaching StalkMarket to buy
fintechStalkMarket already knows when to sell. Now I'm wiring up the harder half — entries. Here's the messy filter that turned 25 candidate buy signals into the five I'd actually trust on HDFC Bank.

Designing a pluggable trailing stop-loss engine
fintechHow StalkMarket's strategy engine works: a pure-function Strategy interface, a discriminated StrategyResult, paise-precision math, and crash-safe deduplication for the trailing stop-loss.
