Builder of systems · Engineer of record · Quietly reliable

This repository represents my public GitHub profile — a distilled view of how I think, build, and lead.

I’m a software engineering consultant with 20+ years of experience, spanning consumer-facing products, large-scale enterprise systems, financial platforms, and internal tooling. My work lives at the intersection of architecture, execution, and accountability — especially in environments where systems are complex, under-documented, or already in motion.

I don’t optimize for noise. I optimize for coherence, durability, and results.

• Systems thinking — architecture, incentives, data flow, failure modes
• Correctness over flash — software should behave predictably under pressure
• Ownership — if I take it on, it gets finished
• Automation — eliminate repetitive work, reduce human error
• Long-term leverage — solutions that compound instead of decay
• Trust — keeping one’s word matters

• Backend-heavy development across PHP, Python, Node.js, C#/.NET
• API-driven systems and service integrations (REST, SOAP, XML, JSON)
• Enterprise web applications and internal business tooling
• Performance optimization, reliability, and observability
• Security-aware development (Veracode Security Labs Champion I–III)

• PowerShell, Bash, and scripting to eliminate manual workflows
• Data migration and normalization pipelines
• Cloud-native deployments (AWS, Azure App Services)
• CI/CD, DevOps practices, and environment parity

• Quantitative trading bots with explicit entry/exit logic
• Indicator-driven decision engines (RSI, ATR, PSAR, trailing exits)
• Position-based accounting (price-in / price-out / realized P&L)
• Minute-level execution with discipline over prediction

• Task-focused assistants
• Workflow augmentation for accounting, research, and education
• Self-hosted and on-prem experimentation over black-box dependency

I’m often brought into environments that are:

• minimally defined
• under time pressure
• carrying technical debt
• mid-transition (mergers, rewrites, migrations)

My role is to make sense of the mess, identify leverage points, and execute a plan that others can build on.

Patterns I default to:

• explicit state over implicit magic
• boring solutions over clever hacks
• deterministic behavior over surprises
• documentation and logs as first-class features

• Financial Services / Banking — Loan origination & servicing platforms, post-acquisition system integration, performance optimization, and operational tooling
• E‑commerce & Marketplaces — Magento, custom PHP frameworks, Solr/SolrCloud, ElasticSearch, large-scale catalog and search systems
• Enterprise & SaaS — API layers, backend portals, internal tools, and data-driven UIs
• Leadership — Lead Engineer, Engineering Manager, consultant, and mentor across teams of varying sizes and disciplines

I’ve led teams, coached engineers, stabilized failing projects, modernized legacy systems, and delivered under compressed timelines.

• Trading and financial tooling
• Backend utilities and automation scripts
• Infrastructure and integration experiments
• Long-lived projects that evolve instead of being rewritten

Some repositories are intentionally minimal. Others are opinionated. All reflect real constraints and real use.

• Languages: English (native), Pashto (native), German (limited), Spanish (elementary)
• Education: B.A. in History — California State University, Long Beach
• Certifications: Zend PHP 5.3, Veracode Security Labs Champion (Levels I–III)

My background in history informs how I approach systems: context matters, decisions compound, and shortcuts have consequences.

Colleagues consistently describe me as:

• reliable
• analytical
• principled
• calm under pressure
• capable of handling ambiguous, high-stakes work

I tend to operate quietly, but I take responsibility seriously — for code, for systems, and for people.

I don’t chase visibility, but I value meaningful collaboration — especially with people who care about quality, clarity, and long-term outcomes.

Build things that still work when nobody is watching.
