Developer tools, automation, and agent systems that stay useful after the first launch.

I’m Ahmed Rehan — a full-stack engineer and solo builder working like a small developer lab: shipping practical tools, tightening reliability, documenting the system, and taking selective freelance work where devtools, webhooks, automation, or AI-agent workflows need clear structure.

Developer lab

A focused bench for tools, systems, proof surfaces, and selective client work — practical experiments that can become reliable products.

Integration reliability lab

Webhook debugging, replay safety, provider-specific diagnosis, and incident artifacts for external integrations that fail in messy real-world ways.

Agent workflow lab

Reusable skills, prompts, host-aware agent assets, and lifecycle tooling so AI-assisted development does not become another dumping ground.

Automation systems lab

Small internal tools, scripts, dashboards, and workflow utilities that are observable, maintainable, and boring in the right places.

Product surface lab

Portfolio, docs, launch pages, resumes, and proof surfaces polished for speed, clarity, accessibility, SEO, and trust.

Featured products

Live product evidence from the places where the work is actually happening: repos, launch surfaces, docs, and systems that can keep growing into paid tools.

Priority #1 · Agent tooling

agent-harness

Node.js / TypeScript CLI for discovering, staging, activating, and wiring reusable AI-agent assets across VS Code/Copilot, OpenCode, Cursor, Zed, Claude Code, and Pi.

  • Reusable agent-asset lifecycle
  • Host-aware activation and wiring
  • Public writing on agent workflow design

Priority #2 · Webhook tooling

Webhook Debugger and Logger

Enterprise-grade webhook testing suite for capturing, inspecting, replaying, forwarding, validating, and mocking webhook traffic in real time without persistent tunnels.

  • SSE streaming and replay loops
  • JSON Schema + signature verification
  • Show HN, Apify, and article proof

Priority #3 · Design-to-code agents

penpot-mcp

AI-agent skill for creating, auditing, and maintaining Penpot design systems, prototypes, tokens, and design-to-code workflows via MCP.

  • Open-source design tooling
  • Agent skill packaging
  • Design system and prototype maintenance

Agent skill curation

antigravity-awesome-skills

Curated collection of 200+ agentic skills for Claude Code / Antigravity / Cursor-style AI-agent workflows.

  • Skill curation
  • Agent workflow packaging
  • Practical AI-development assets

Product and tooling threads

Supporting work that shows range beyond the headline tools: visual systems, challenge builds, mobile context products, and data-quality workflows.

Aesthetic Palettes

Open-source color palette generator focused on WCAG-aware visual tooling, typography, UX research, and zero-cost infrastructure.

code-the-countdown

Google I/O 2026 Code the Countdown challenge project using TypeScript, React/Next.js, canvas, motion, Web Audio, and WebGL-oriented UI work.

InterActNote

Android-first call-time context and relationship notes product focused on useful, practical in-call context.

DataGuard

Data quality and ETL validation product direction for CSV, Excel, JSON, and structured-data workflows.

Public work feed

Recent launch notes, technical posts, and repository activity pulled from public surfaces when available. The curated fallback stays useful even when third-party APIs are slow or blocked.

Freelance proof surface

Upwork profile, made specific

Open Upwork
Client-facing profile

Full-stack engineer for devtools, webhooks, automation, and AI-agent work.

The Upwork surface is being tightened around practical engineering outcomes: webhook/API debugging, internal tools, automation-heavy products, developer tooling, and reliable async delivery.

Current Upwork positioning Full-stack engineer for devtools, webhooks, automation, and AI-agent work

Client-facing profile now points at practical tooling, workflow systems, reliability, and async delivery.

Availability signal Full-time capacity

Read from the profile API as a public profile signal; still best used for selective, focused work.

Portfolio depth 20 portfolio projects visible

API-read public portfolio surface shows a broad historical proof base to refine and prioritize.

Next proof additions Webhook Debugger · agent-harness · penpot-mcp · ar27111994.dev

Approval-gated Upwork API plan is ready for adding these as public Other Experience proof entries.

Public Upwork edits are approval-gated: profile title/overview are drafted for manual/UI update, while API-writable proof additions are staged separately and will not be published without explicit approval.

Proof links: certifications, venture, OSS/freemium

Verifiable background signals: certifications, partner identity, older shipped projects, and founder/operator work that still supports the current devtools and automation direction.

Funding / sponsor links

Lightweight ways to support the public lab: maintenance, docs, product experiments, and faster shipping on open-source tools.

For direct sponsorship/partnership, email [email protected] or use WhatsApp.

Core capabilities

The recurring work pattern across the portfolio: practical tooling, integration reliability, automation, agent workflows, performance, and production-minded delivery.

Proof surfaces

Primary surfaces for technical credibility, client trust, launch proof, and community history. Discord: ar27111994.
