The client uploads bytes directly to S3-compatible storage via a presigned URL — the backend checks quota, signs the URL, and tracks metadata, but never touches the bytes. Ships as two clients (anonymous web one-pager + authenticated Electron menu-bar app) over one Go API, sharing a custom React UI library. **Impact:** A zero-byte-touch file-sharing API: presigned PUT/GET, share codes, feature flags, and a BYO-bucket Electron desktop client alongside an anonymous one-pager web app. Engineered for predictable cost (the backend never proxies bytes) and clean separation across four independent packages. **Tech:** go, gin, mongodb, redis, react, typescript, vite, electron [Live](https://usefilesalad.xyz) · [Backend](https://github.com/spiderocious/file-salad-api-service) · [Web](https://github.com/spiderocious/filesalad-web) · [Desktop](https://github.com/spiderocious/file-salad-electron-desktop-app) · [UI Library](https://github.com/spiderocious/file-salad-ui-lib) ### Dipstick (SaaS) A digital station logbook for Nigerian filling-station owners running one to ten branches. Managers record the day end-to-end — opening dip, attendant pump readings, tanker deliveries, expenses, closing dip — and the owner reads a single morning roll-up across every branch. It is the cashier's worn exercise book made shared, signed, and impossible to tamper with after the fact. **Impact:** Audit-grade operations ledger where integrity comes from posting, signing, and an immutable void idiom rather than hardware telemetry. Built as an Nx + pnpm monorepo: an Express + MongoDB API with multi-document transactions and a permission-keyed RBAC catalogue, a React 19 + Vite operator app, and a Next.js marketing site — all sharing pure-TS domain logic. Money is stored end-to-end in integer kobo (bigint) to eliminate float drift in reconciliation. **Tech:** typescript, react, vite, tailwind, node, express, mongodb, fintech [Monorepo (web, API, marketing site)](https://github.com/spiderocious/dipstick) ### TaxLens (Fintech) A personal income tax tool for Nigerians under the Nigeria Tax Act 2025 (effective 1 January 2026). A visitor enters income manually, loads sample data, or uploads a bank statement; TaxLens computes their tax position under the new regime, shows what changed versus the old PITA rules, and lets them ask grounded follow-up questions. No accounts, and no user data is stored. **Impact:** A statute-grounded tax engine where the LLM never invents a number: a pure-TypeScript NTA 2025 calculator owns every figure, while a two-tier OpenAI pipeline (cheap gpt-4o-mini gate + gpt-4o analysis) only extracts and classifies bank-statement inflows. Built as an Nx + pnpm monorepo — Vite/React 19 frontend, Express + MongoDB backend with SSE live status, a circuit breaker, and an LLM stub transport for deterministic CI. **Tech:** typescript, react, vite, tailwind, node, express, mongodb, openai, fintech [Live](https://usetaxlens.xyz) · [Monorepo](https://github.com/spiderocious/taxlens) ### Medcord (Healthcare SaaS) Multi-tenant hospital management SaaS. Hospitals sign up, set up a workspace, and run patient management, EMR, labs, and asset tracking from one platform. Go + Gin backend, React 19 frontend on Feature-Sliced Design. Built by Oluwaferanmi Adeniji — recognised by the Nigerian Presidency (Buhari) as one of 10 youth innovation winners on the maiden National Youth Day, 2020. **Impact:** Multi-tenant hospital platform unifying patient management, EMR, labs, and asset tracking. Go 1.25 + Gin backend with i18n and generics-based ServiceResult; React 19 + Vite frontend built in disciplined, spec-verified phases. Built by an engineer formally recognised by the Federal Government of Nigeria in 2020 (Presidential National Youth Day award, 60 Day App Challenge). **Tech:** go, gin, mongodb, react, typescript, vite [Monorepo](https://github.com/spiderocious/medcord-app) · [Landing](https://github.com/spiderocious/medcord-landing-page) · [Live](https://usemedcord.xyz) · [Presidential Recognition (2020)](https://msmeafricaonline.com/national-youth-day-buhari-recognises-15-youth-innovators/) ### BuffByte AI (100+ Creators) AI-powered content optimization platform with real-time analysis, trend discovery, and professional teleprompter.

Tutor identities stay masked until both sides choose to share contacts. **Impact:** Connection-fee marketplace that monetizes introductions, not lessons: verified tutors, masked identities, on-platform real-time chat, and a trust team for moderation. Express + Socket.io backend, React frontend. **Tech:** react, typescript, node, express, mongodb, socketio [Live](https://usepracket.xyz) · [Frontend](https://github.com/spiderocious/pracket-web) · [Backend](https://github.com/spiderocious/pracket-backend) ### Solon (Political Intelligence Platform) Political intelligence and campaign infrastructure for Nigeria, named after Solon of Athens. An election simulator, AI voter segmentation, agent coordination, finance compliance, and a live war room — delivered as a pnpm monorepo of five apps and shared core/api/ui packages. **Impact:** Probabilistic election simulator and full campaign stack: model vote share across structural levers and issue shocks, segment voters, coordinate field agents, track finance compliance, and run an election-day war room — with ethical guardrails baked in. **Tech:** typescript, react, vite, node, express, nextjs [http://usesolonai.netlify.app/](http://usesolonai.netlify.app/) · [https://github.com/spiderocious/solon-ai](https://github.com/spiderocious/solon-ai) ### Go File Service (Go Microservice) Lightweight Go file proxy service. Generates presigned upload and view URLs for any S3-compatible storage (Tigris, t3.dev, AWS S3) — two endpoints, zero database, with built-in memory and activity logging. **Impact:** Stateless Go + Gin glue between any app and S3-compatible object storage: server-generated UUID keys, presigned PUT (15m) and GET (1h) URLs, and per-request memory/counter logging — no database, tiny footprint. **Tech:** go, gin, s3 [https://github.com/spiderocious/go-file-service](https://github.com/spiderocious/go-file-service) ### Design System Clawd Agent (AI Dev Tool) A Claude Code agent ("Studio") that designs a complete design system from a one-paragraph idea — interviews you, proposes stances from a 25-style catalog, shows side-by-side variations, builds the whole system as static HTML, and a second agent ships it into your real React app. **Impact:** A two-agent Claude Code system: a designer agent turns a prompt into a full HTML design system on a gallery, and an implementer agent reads your existing React repo's conventions and translates the design into matching .tsx — never inventing design, always showing diffs first. **Tech:** html, claude-code, anthropic [https://github.com/spiderocious/design-system-clawd-agent](https://github.com/spiderocious/design-system-clawd-agent) ### Ohlify (Mobile Marketplace) Mobile app (iOS + Android) that connects clients with professional experts — consultants, lawyers, mentors, podcasters — for paid 1:1 calls. Professionals set their rates, share a booking link, and get paid to their wallet via Paystack. **Impact:** Two-sided expert-call marketplace: discover → book → pay → call → review, with KYC onboarding, in-app wallet/payouts via Paystack, real-time RTC calls, and calendar invites. Flutter app + TypeScript backend. **Tech:** flutter, dart, typescript, node, paystack, webrtc [Live](https://ohlify.xyz) · [Mobile App](https://github.com/spiderocious/ohlify-app) · [Backend](https://github.com/spiderocious/ohlify) ### WorkSight (Full-Stack + Desktop) Take-home assignment proctoring you can actually trust. A reviewer web app, a Node backend, and an Electron candidate app that captures timestamped screenshots during a timed session — so reviewers score the candidate, not the model. **Impact:** Three-surface system (backend + reviewer web + Electron desktop) for trustworthy take-home assessments: timed sessions, periodic screenshot evidence via presigned URLs, auto-close, and submission scoring — built with a privacy-first 'what it deliberately does NOT do' charter. **Tech:** react, typescript, vite, tailwind, electron, node, express, mongodb [https://worksight.netlify.app](https://worksight.netlify.app) · [Web/UI](https://github.com/spiderocious/worksight-ui) · [Backend](https://github.com/spiderocious/worksight-backend) · [Electron](https://github.com/spiderocious/worksight-electron-app) ### Atuko (Chrome Extension) Chrome MV3 browser automation extension for engineers (Yoruba for 'driver'). Record, build, and run multi-step workflows directly in Chrome — no cloud, no account. Every workflow compiles to portable, version-controllable JSON. **Impact:** Local-first browser automation with 18 step types, an action recorder with stable selector generation, branch/loop logic, dry-run validation, and run history — all as portable JSON workflows that can be generated by AI agents. **Tech:** typescript, react, chrome-mv3, vite [https://github.com/spiderocious/atuko](https://github.com/spiderocious/atuko) ### Kobiowu (OSS Library) Framework-agnostic, headless overlay orchestration engine.
