Selected work · 8 real systems

Eight systems weactually shipped.

Real builds, with client names abstracted under NDA and the engineering described exactly. No fabricated logos, no invented metrics, no agency theater. What each system does, and how it was built.

How we describe this work

Every system here is real. Where a client is under NDA, the name is abstracted and the brand omitted; products we built for ourselves are marked as such. We describe what each system does and how it was engineered, never a borrowed logo or a number we can't stand behind.

    attirebytatsavi.com · D2C apparel

    A full-stack apparel storefront shipped end-to-end for a D2C brand: storefront, checkout, payments and admin, self-hosted and handed back.

    Next.js 16 front-to-back with Razorpay checkout wired to payment webhooks, NextAuth v5 sessions, a Postgres + Prisma data layer, an image pipeline and an admin dashboard, deployed on a self-hosted Azure VM with no SaaS lock-in.

  2. AIProduct

    Nexus AI

    Multi-agent orchestration framework

    A framework for orchestrating fleets of AI agents: plan a DAG of work, run it in parallel, recover from failure, and never blow the token budget.

    A DAG planner with topological sort + parallel execution, backtracking with retries and fallback agents, real-time token-budget enforcement, and a visual builder. Python / FastAPI + Next.js, Postgres / pgvector + Redis, LangChain.

  3. SaaSUnder NDA

    StrataPay

    Multi-tenant SaaS billing platform

    A billing platform built from scratch that bills correctly under multi-tenancy, the part most teams get subtly, expensively wrong.

    Per-tenant isolation that escalates from row-level security to dedicated schemas, deterministic proration with a verifiable audit trail, and webhook delivery with retries and a dead-letter queue. NestJS + Next.js + Postgres + Stripe.

  4. Real-timeUnder NDA

    Synapse

    Real-time collaboration engine

    Figma/Docs-class live collaboration (multiple cursors, no conflicts, no lost edits), built from first principles with no third-party sync library.

    An authoritative Go hub runs the sync: operational transforms for document edits and CRDTs with vector clocks for presence. Clients connect over WebSocket, with WebRTC as an optional peer-to-peer fast-path for presence above a peer threshold, falling back to WebSocket. Go backend, SvelteKit front. The hard computer-science, done properly.

  5. MobileUnder NDA

    Trackr

    Cross-platform health app

    A production React Native app that reads native health data and stays correct offline, then reconciles cleanly when it reconnects.

    A custom native health bridge in Swift + Kotlin and an offline-first sync engine built on version vectors, so the app is fully usable with no signal and never loses or double-counts data on merge.

  6. AutomationProduct

    SpiderBox

    Anti-bot scraping toolkit

    A pip-installable toolkit that collects data from sites built to stop exactly that, and returns it as clean, structured output.

    Fingerprints and evades Cloudflare, Akamai and DataDome using a stealth browser and TLS rotation. The same fingerprinting discipline we now apply to data intake across the studio.

  7. On-chainUnder NDA

    StakeVault

    DeFi staking protocol

    An on-chain staking protocol with no admin key to trust and reward math that's provably correct, backed by an exhaustive test suite.

    Solidity with a Diamond proxy and no admin key, time-weighted balances and decay-math rewards, and a full fuzz / invariant / fork test suite. Money-handling code held to money-handling standards.

  8. SecurityUnder NDA

    Redarc

    Automated vulnerability scanner

    A scanner that doesn't just list vulnerabilities. It ranks them by real risk and escalates the exposures that have been sitting open too long.

    CVE matching against the NVD feed plus a Bayesian risk engine that escalates long-standing exposure. Django backend, Nuxt front end.
