01 · Featured work
A kingdom-building deck roguelike written in blood and ink.
Build a reign from the ruins of a scarred world. Court the kingdom, marshal your cards in battle, and survive branching story events that remember how you fight. 210 cards, five bosses, and a hand-crafted Scarred Ink art style. Built in Godot 4.
The cricket management sim that puts you in the dugout.
Run the club from the boardroom to the final over, transfers, training, tactics, finances and the media circus. A deep, faithful cricket management simulation for PC.
Learn Japanese with Leo. Warm, free, and built to work.
An offline-first Japanese companion from your first kana to advanced study. 1,500+ words across CEFR & JLPT tiers, grammar, handwriting practice, spaced repetition and seasonal stories, no ads, no paywalls.
A cozy sky-isle game about tending wishes and remembering kindness.
Weave thread from dream blooms, care for visitors walking through grief, generosity and identity, and light the Sky Almanac with memories worth keeping.
02 · Tools & platforms
Paper-first options trading intelligence.
A 12-agent research brain that scans markets, weighs volatility, flow and sentiment, and only ever proposes trades it can prove, paper execution only.
An autonomous vertical-video factory.
Harvests trends, writes and scores scripts, sources b-roll, synthesizes voiceover, and publishes captioned shorts to YouTube without a per-video service fee.
Evidence-led tax preparation for South Africa's ITR12.
Canonical tax modelling, year-versioned rules and deterministic calculations, built so every number can be traced back to the law it comes from.
03 · Browser tools
Single-file Tampermonkey scripts that turn numbers-heavy games into clear decisions. Free, open source, and local to your browser.
Your personal race engineer for Grand Prix Racing Online.
Tyre strategy, car setup, fuel loads and upgrades, a floating race engineer on every page, without burning through your API budget.
A smarter way to play TrophyManager.
Best XI, mentality and set-piece calls from the trusted R5 engine, plus youth scouting and stadium ROI, inline in the game.
Turn From The Pavilion into a game of decisions.
Toss calls, training plans, transfer values and youth scouting backed by actual numbers instead of gut feel.
04 · The studio
Astraiva was founded by Tushant Sharma to make software that feels considered. Some projects are public, some are still private, and each one is given the time it needs.
Every screen is designed by hand and cared for long after launch.
Your data belongs to you. Local when it can be, private when it can't.
Good tools shouldn't be locked behind paywalls. When we charge, it's for the product, never the ads.
Tests, quality gates and honest docs. We ship things we're proud to put our name on.
