built TempFS, temporary file sharing service

- upload a file, set a use limit and expiry, get a link
- no account needed for guest uploads; pro tier adds password-protected links
- share via email
- server never touches your file bytes, direct browser-to-R2 via presigned URLs

I heard the reason why Amazon reported on Fable to the government is because Fable was unable to fix how bad AWS's UI is.

2. AppendEncode()

it writes into a buffer you supply instead of allocating one. zero extra allocations when capacity fits. pair it with sync.Pool for net.Conn writes and you get allocation-free encoding on every request.

[Manav @radioac7iv]

3. Decode*()

each RESP type has its own Decode function, DecodeSimpleString, DecodeInteger, DecodeBulkString etc.

it parses a RESP-encoded byte slice and returns the corresponding Go value of that type.

[Manav @radioac7iv]

1. Encode()

It serializes a Go value into a fresh RESP byte slice. it starts with a 64-byte buffer and grows as needed. array elements write into the same buffer recursively, so even nested arrays land in a single allocation.

[Manav @radioac7iv]

yo, so i built resp-codec, a codec library for Redis Serialization Protocol v2 written in golang.

it supports all RESP2 types: simple strings, errors, integers, bulk strings, arrays, and null variants.

Here's how it works 👇

boris cherny goes on a podcast every three months and says something like “i’ve stopped breathing now i just wrote a breath.md” and the next day everyone in sf stops breathing

[Manav @radioac7iv]

how it works:

- upload: browser → presigned PUT → R2 directly; server only stores metadata
- download: one Postgres query atomically checks expiry, verifies password, claims the use
- no cleanup job, R2 TTL handles deletion, expired links blocked at the app layer

i've been reading agave's source code for a few weeks and have now started building toy versions of different components for fun with gossip being the first.

it has:
- bloom filter with fnv hashing
- crds table with conflict-free timestamp resolution
- gossip protocol messages over udp
- multi-node convergence across gossip rounds

i might also come up with @solana 's own version of "build your own x" lol

link to the repo below:

[aditya. @bit2swaz]

and with that, i'm now open to work.
remote only. internship, contract, part-time, or paid trial. anything works.

about me:
18. first-year CS student. got into systems and infra in october 2025. haven't stopped since.

primary languages: Rust and Go. C/Python/TS when needed.

---

things i've built:

Rust:
> Arbx: autonomous MEV arbitrage engine. 186 tests, 17ns AMM calculation, $31 mainnet budget. launching april 2026
> Shadow Index: Reth ExEx Ethereum indexer. 4.08ms latency, 71k tx/sec (dm'd by @gakonst after this post)
> Mempool Sniper: event-driven Ethereum mempool monitor. <500ms detection latency
> Rusty Redis: Redis clone. 1.4M+ ops/sec
> Merkle Trie: Ethereum MPT implementation. O(1) state verification
> Cold CLI: HD wallet generator. zeroizes RAM on drop

Go:
> Orion: distributed container orchestrator. self-healing cluster in under 2 seconds
> Aether: distributed SQL database. Raft consensus, Postgres wire protocol
> CrisisMesh: offline-first mesh network. guaranteed delivery during partitions
> VelocityCache: remote build cache. 231x faster than Turborepo (at local cache restoration)
> Prism: serverless, instant database branching under 300ms for any PostgreSQL

C:
> lithos: LSM-tree storage engine. 72k+ writes/sec, 97k+ reads/sec. MVCC.

---

open source (merged):
> token-2022 (Solana)
> anchor (Solana, approved)
> CometBFT (3 merged, 3 open)
> cosmos-sdk
> Gaia
> Sovereign SDK

---

wrote 4 technical deep dives. MEV, Ethereum Merkle Trie, Redis, and LSM-trees.

---

looking for:
systems, protocol, or blockchain infra. backend works too.
Rust or Go. remote only.

not looking for:
frontend, full-stack, anything off the metal.

[Amaan @dextertwts]

was reading about amazon's S3 bucket and object storages

so i built frusta , my S3 styled manual chunk upload engine

- out of order+ parallel chunk acceptance
- resume and stream fail logic for chunk uploads
- idempotent file writes/db writes
- atomic renaming from temp to final folder (check docs)
- merge failure handling
- node pipelines for reqStream,writeStream and merge w backpressure-safe transfer
- explicit upload states (init/uploading/completing/completed/failed)
- feature based scalable architecture and middlewares

- also learnt about testing (23+6) and benchmarks (k6) along the go

@farhatkadiwala_ exactly, it's sooo soothing.

[hrdk @hrdktwt]

tired of outdated startup job boards?
I built an interactive map that shows every fresh startup role in blr
- it auto updates itself every 72 hours automatically
- and it's fully free to use, no login required

[Manav @radioac7iv]

@farhatkadiwala_ @vrajdesai78 Well written! been struggling with this for a few weeks now and still have no idea lol but excited for what comes next

yo, built a TOTP authentication service. It works with any authenticator app (Google, Microsoft, etc.)

it implements RFC 6238 (extension of RFC 4226) to generate HMAC - based OTPs, derived from fixed time steps.
