Mayank Tiwari
i build backends that survive the load, scale when needed, and keep state consistent.
backend engineer building systems that scale, APIs that make sense, and occasionally maxxing tokens for no good reason. usually reading, writing, or listening to the same song for the 51st time.
writing
tech, stories and the occasional rant. whichever wins the coin toss that week.
work
engineering card payment solutions. building AI agents to tackle pain points across engineering (obv. on-calls) and customer success. learning. breaking. shipping.
tools i reach for
hover or tap one to see what i use it for.
java my default for services that need to run for years.
notes to self
rules i keep relearning. open one for the why.
make it boring
boring technology fails in ways you already know how to fix at 3 a.m.
every retry needs jitter
synchronised clients turn a blip into an outage. randomness is a load balancer.
idempotent or it didn’t happen
if an operation can’t safely run twice, the network will eventually prove it.
measure before you cache
a cache hides a slow query, it doesn’t fix it. find the slow part first.
timeouts on everything
a call without a timeout is a thread you’ve lent out forever.
write the postmortem anyway
small incidents are cheap lessons. big ones are the same lesson, paid in full.
library
books, music and films i keep coming back to.
idiomatic go without the hand-holding. slowly unlearning my java habits.
things i've built
frameflux ffmpeg · sqs · fargate · s3adaptive video streaming: upload once, transcode to every resolution, play anywhere.
blogai typescript · genkit · postgresan agent pipeline that turns a video into a draft blog post.
smartdraw websockets · express · postgresa multiplayer whiteboard over websockets.guestbook
pin a note: say hi, leave a book, or tell me a song i should hear.
