We buildsoftware thatships and scales
Didd Tuni LLC is a U.S.-registered software engineering consultancy specializing in high-performance React & TypeScript applications, design systems, and full-stack architecture for global clients.
Engineering services built for impact
React & TypeScript Applications
Production-grade frontends using React, Next.js, and TypeScript. From SPAs to microfrontend architectures, we build interfaces that perform at scale with accessibility baked in.
Design Systems & Component Libraries
Custom, WCAG-compliant component libraries built on modern primitives like Radix UI and shadcn/ui. Shared foundations that eliminate visual drift across your product suite.
Full-Stack Architecture
End-to-end platform engineering with Node.js, NestJS, GraphQL, and cloud infrastructure. Clean architecture patterns (DDD, Onion) that keep your codebase maintainable as you grow.
CI/CD & Infrastructure
Build pipeline optimization, containerized deployments on AWS EKS, and infrastructure automation. We've cut deployment times by 87% and infrastructure costs by 30%.
Technical Leadership & Advisory
Architecture reviews, code quality audits, and engineering standards consulting. Helping teams adopt best practices, improve velocity, and reduce technical debt.
Performance Engineering
Core Web Vitals optimization, rendering performance tuning, and load time reduction. Real, measurable improvements — like 1.2s LCP reduction and 40% faster page loads.
Case study
AKASHA Foundation
Open-Source Web3 Foundation · Ethereum Ecosystem · Sep 2022 – Jan 2026
As part of a long-term B2B contract with AKASHA Foundation, we worked with a team of engineers on AKASHA Core, a composable framework for building Web3 social products. The work included frontend architecture, component systems, performance optimizations, and engineering standards across a distributed team.
Engagement process
Initial Conversation
We start with a direct conversation about your team, product priorities, and where senior engineering support is needed most.
Technical Alignment
We align on stack, responsibilities, contract shape, and how I plug into your existing team, workflow, and delivery expectations.
Embed & Deliver
I work as part of your team in your stack, contributing directly to architecture, implementation, reviews, and shipping production work.
Maintain & Extend
The engagement continues based on team needs, with clean handoff, shared context, and no dependency on extra agency layers.

Kind words from people we've worked with
“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.”
“He has an exceptional ability to design robust foundational architecture, deeply understand complex product requirements, and translate them into clean, effective code. In high-stakes situations involving critical clients, Didd consistently delivered — going above and beyond without compromising quality or security.”
“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.”
