I am a Senior Chromium Developer with over 15 years of professional C++ experience and a deep specialization in custom Chromium-based browser development.
Across my career, I’ve engineered and delivered 8+ production-ready Chromium forks—each customized for performance, privacy, and automation—serving millions of end users worldwide.
As one of the pioneers behind the Thorium browser, I helped achieve a 72% performance boost over vanilla Chromium when handling 25+ tabs, through low-level optimizations in thread scheduling, renderer coordination, and GPU process management.
I am also recognized as the only Top-Rated Plus Chromium developer on Upwork with a 100% client success rate, consistently delivering stable, high-performance, and feature-rich browser builds for enterprise, Web3, and automation use cases.
Core Chromium Expertise
C++ / Chromium Architecture: Deep understanding of Browser, Renderer, GPU, Network, and Utility processes within the Chromium ecosystem.
Performance Optimization: Achieved multi-threaded rendering improvements, GPU pipeline tuning, and optimized resource caching for faster multi-tab browsing.
Custom Networking: Implemented per-tab proxy routing, SOCKS/HTTP proxy management, and header-level fingerprint control with unique network contexts.
Fingerprint Isolation: Developed systems for independent TLS fingerprints, WebRTC IP masking, Canvas/Audio randomization, and GPU vendor spoofing.
Automation & Control: Added headless and stealth automation modes, WebDriver extensions, and native Win32 automation layers for controlled browser behavior.
Privacy & Security Enhancements: Introduced site isolation, profile sandboxing, script-level content blocking, and policy-driven extension control.
UI & Shell Customization: Designed lightweight shells using Aura/Views, floating and minimal UIs, and integrated native dialogs and overlays for custom workflows.
Web3 & Decentralization: Integrated dApp and wallet modules, blockchain domain resolution, and token-based identity bridging directly into the Chromium runtime.
Cloud & Sync Features: Built multi-profile environments, encrypted user data sync, and secure cloud configuration fetchers for distributed deployments.
Extension Runtime Enhancements: Extended Manifest V3 functionality, content-script bridges, and secure background messaging for enhanced extension APIs.
Daniyal A. earns an estimated $7.4k/mo. That's 4.9× the typical freelancer and more than 99.76% of everyone we track.
Enterprise Security: Integrated hardware-based encryption, group policies, admin dashboards, and secure sandbox enforcement at the kernel and user levels.
Performance Telemetry: Added in-browser analytics and metrics collection via PDH counters, system telemetry daemons, and real-time logging to Kafka/RabbitMQ.
Rendering & GPU Enhancements: Tuned Skia rendering, GPU compositing, and raster threading to reduce frame latency and improve visual performance.
Installer & Deployment: Created custom MSI/MSIX installers, auto-update systems, and background daemons for silent installation and maintenance.
Key Engineering Contributions
Architected multi-process proxy management with per-tab network isolation and individual WebView identity contexts.
Designed sandbox-hardening policies and site isolation logic to prevent cross-origin data leaks in high-security environments.
Optimized GPU command buffer scheduling for smoother rendering under heavy tab concurrency.
Integrated AI-driven prompt layers and automation hooks for browser-assisted workflows.
Built telemetry subsystems to measure CPU, memory, and render-process efficiency, improving diagnostic capability.
Delivered cross-platform stability improvements, custom DevTools integrations, and rapid profile containerization.
