about me

From Developer to Architect
Building Systems that Last

Hi, I’m Syed Usama Haider Kazmi, a Software Architect with {{ experienceYears }}+ years of experience spanning mobile, web, and full-stack development. Over the years, I’ve worked my way from hands-on developer to engineering leader, designing, developing, and delivering solutions that merge creativity with technical depth.

My journey has taken me through roles as a mobile app developer, backend engineer, team lead, project manager, and now as a director, leading high-performing teams accross the globe at Delve Health LLC (USA) and completing many successful freelance and enterprise projects across Clinical Trials, Tele-Health, FinTech, MedTech, EdTech, and SaaS platforms.

I specialize in requirement gathering & analysis, risk identification & mitigation, system architecture, product scalability, and clean engineering design. Transforming large monoliths into modular, reusable ecosystems.

I believe good engineering isn’t just about writing code, it’s about designing clarity, consistency, and collaboration into every layer of a product.

Clinical StudyPal, Delve Health LLC ↗
SaaS Re-Architecture

Role: Director of Product Engineering & Development
Domain: Clinical Trials | ePROs | eCRFs | eConsents | Tele-health & IoT

Re-engineered Delve Health’s clinical trial platform into a modular-driven SaaS system supporting multi-trial operations, IoT devices, ePROs, eCRFs, eConsents, role-based precision and more. Designed a plug-and-play OAuth 2.0 layer for wearable integration and a BigQuery-powered data warehouse managing large, concurrent datasets with scalability in mind.

  • 1. 4× faster feature delivery
  • 2. 80% faster IoT device onboarding
  • 3. Scalable across multiple active trials
  • 4. Large-scale, high-volume data handling

DataFinder
To Developers, By a Developer

Role: Creator & System Architect
Domain: Developer Tools | Data Engineering | Laravel Ecosystem

Built a developer-first data interaction framework to simplify dataset exploration and exports without repetitive code. Combines a modular backend built on config driven system with a UI-driven frontend for instant filtering, searching, and exporting.

Features a two-layer pipelineBackend chunk retrieval with SheetJS-based frontend rendering, enabling real-time, multi-sheet exports. It also includes stub-based configuration and recursive data awareness for clean, declarative dataset definitions.

Reflects my engineering philosophy: abstraction with control, elegant architecture, and developer empathy and continuously evolving for the Laravel community.

  • 1. Simple boolean-based options: filter, order, search, export
  • 2. 100k+ rows handled per export with minimal memory
  • 3. Multi-sheet, chunk-based concurrent data handling
  • 4. Open-sourced under MIT

Architecture Principles
How I Design Systems

Over time, I’ve defined a set of architecture principles that guide how I design, structure, and scale software systems. Every project I lead follows the same foundation clarity, modularity, and adaptability.

From API-first design and domain-driven structure to consistent naming conventions and reusable components, the goal is always to make systems predictable and easy to evolve. I rely on clean data models, layered separation, and continuous delivery pipelines to keep architecture maintainable and scalable as products grow.

  • 1. Modular codebase structure
  • 2. API-first, integration-ready design
  • 3. Clear separation of layers and services
  • 4. Scalable build and deployment pipelines

Engineering Systems, That Scale
Modular • Measurable • Maintainable

Over the years, I’ve architected, developed, and led products that balance engineering clarity with product adaptability.

Each system brought a unique challenge, rebuilding products from the ground up or transforming raw ideas into reliable, scalable software.

My experience spans requirement analysis, architecture design, coding standards, and full development lifecycles. I focus on modular system design, API-driven architectures, and microservice-inspired patterns within structured monoliths. This includes optimized database schemas, scope definition, risk management, and aligning every component, from backend to integrations, around performance, maintainability, and business impact.

The following case studies reflect my approach to technology: clear architecture, reusable design, and developer empathy.
