AKASHA UI Component Library

Senior Frontend Engineer · Sep 2022 – Feb 2026 · AKASHA Foundation (Web3 / Ethereum)

AKASHA World — a decentralized social platform on Ethereum — required a scalable component system for its microfrontend architecture. The existing library relied on monolithic components with rigid APIs (18+ prop buttons, deeply nested conditional branches, twind string concatenation) — making customization brittle and extending functionality costly. I redesigned the system around composable, compound component patterns built on shadcn/ui and Radix primitives.

  • Led development of 33 React components — 20 custom domain primitives and 13 extended shadcn/ui foundations — using Compound Component patterns, Radix UI primitives, Tailwind CSS, and TypeScript
  • Adopted across 8 microfrontend apps within AKASHA World's single-spa platform, reducing UI development time by ~30% and eliminating cross-app visual drift

Virtualized Feed Scroll Restoration

Senior Frontend Engineer · AKASHA Foundation · Technical Deep-Dive

Infinite scroll feeds with dynamic content heights caused scroll-jump on navigation and degraded LCP. Browser-native scroll restoration doesn't work with virtualized lists — items aren't in the DOM on remount — so I engineered a custom persistence and restore layer from scratch.

  • Reduced Largest Contentful Paint by 1.2s through virtualized rendering and scroll position persistence
  • Eliminated scroll-jump regressions on back-navigation across all virtualized feeds

BSI Knowledge — Standards Platform

Senior Frontend Engineer · Mar 2021 – May 2022 · TheoremOne (client: British Standards Institution)

The UK's National Standards Body needed to transition from individual subscriptions to enterprise-wide access — syncing 100,000+ standards in real time across 50+ global organizations, with role-based access control, version tracking, and Shopify-gated content management.

  • Implemented real-time sync of 100,000+ standards across 50+ enterprise organizations using Next.js and TanStack Query
  • Shipped 'My Collection' — a library management system adopted by 50+ orgs that reduced compliance audit prep time by 40% through automated version monitoring and RBAC

SpineEditor — Rich Text Editor Library

Founder & Lead Engineer · 2025 – Present · Open Source

Existing rich text editors force a choice between control and capability — lightweight libraries lack document-grade features, while full editors are monolithic and hard to extend. SpineEditor is an open-source library targeting Google Docs-grade editing with a headless, plugin-driven architecture that gives developers full control without sacrificing power.

  • Designed a strict rendering pipeline: Browser → Substrate → Intent → Plan → Transaction → Apply/Map → Normalize → Commit → Renderer → DOM — separating editing intent from document mutation for predictable, testable behavior
  • Built on branded types for compile-time safety and discriminated unions for document node modeling — enforcing correctness at the type level rather than through runtime checks

// Global Reach

Built on 15 years of shipping

I operate globally via B2B contract through Didd Tuni LLC (U.S.-registered, Delaware) — which means simple vendor contracts, no international hiring complexity, and no payroll overhead. I work across US/EU time zones with distributed, async-first teams.

I work best as a senior IC who thinks architecturally. I own problems end-to-end — from RFC to production — and I care deeply about accessibility, performance, and code that the next engineer can reason about. I've also scaled an engineering team from 0 to 8 as CTO, but my focus is hands-on delivery.

Currently building SpineEditor — an open-source, Google Docs-grade rich text editor with a headless core and plugin architecture.

Kind words

Didd distinguished himself as a high-performing engineer with exceptional technical aptitude. He possesses a sharp level of understanding that allows him to grasp complex architectural requirements almost immediately. He is a start-to-finish engineer who can take a vague concept and transform it into a production-ready feature with minimal supervision.

Marius DarilaSenior Software Engineer · Previously at AKASHA Foundation

Didd stands out as a strong, capable engineer who quickly understands complex problems and works with a high level of independence. He approaches tasks thoughtfully, cares about quality, and follows through to completion — not just aiming to make things work, but to make them work well and remain maintainable over time.

Didd is an exceptional Senior Software Engineer with a rare ability to bridge design and implementation seamlessly. He consistently takes the time to deeply understand design intent and translates it into high-quality, precise implementations, always with great attention to detail and strong engineering standards.

Basma AlghanimLead Product Designer · Previously at AKASHA Foundation

I can definitely recommend him as a full-stack developer that pays attention to details. He onboarded to our existing codebase quickly and was able to ship changes with minimum guidance. Didd is the type of person that is easy to communicate with and collaborate with.
