Senior Software Engineer
Long-term Product Development • React Native • TypeScript • Backend Systems

I am a senior software engineer with experience building, scaling, and maintaining long-running production systems.
I specialize in working on complex products over extended periods, where stability, architecture, and ownership matter more than quick delivery.

I prefer collaborating with teams and clients who are building serious products meant to last for years.

• Senior engineer with strong end-to-end ownership
• Experienced in multi-year product development
• Comfortable working on existing, complex codebases
• Known for solving hard, non-obvious technical problems
• Strong focus on maintainability, scalability, and clarity

• TypeScript
• JavaScript
• SQL (working knowledge)

• React Native (production-grade applications)
• React
• Component-driven architecture
• Performance optimization for mobile apps

• Node.js
• Express
• REST API design
• Secure and scalable API integrations

• Recoil
• Redux
• Predictable state management
• Clean separation of business logic and UI

• Git & GitHub (professional workflows)
• Debugging large codebases
• Refactoring legacy code safely
• Code reviews & technical mentoring

Over the years, I have worked closely with teams on real production products, including:

• Long-running mobile applications with continuous feature evolution
• Backend services supporting business-critical workflows
• Products with frequent data synchronization and API integrations
• Systems where performance, stability, and reliability were critical

My role often involved not just adding features, but improving architecture, reducing technical debt, and making the system easier to maintain for the long term.

Some examples of the kind of challenges I regularly handle:

• Refactoring tightly coupled legacy code without breaking production
• Stabilizing apps suffering from inconsistent state and hard-to-reproduce bugs
• Designing scalable state management for growing feature sets
• Handling edge cases in real-world data and user behavior
• Improving performance and responsiveness in large React Native apps
• Making systems easier for new developers to understand and contribute to

I am comfortable working through ambiguous, messy problems and turning them into clean, understandable solutions.

• Prefer long-term engagements and deep involvement
• Strong sense of ownership and responsibility
• Clear and honest technical communication
• Proactive about identifying risks and technical debt
• Write code that is easy to read, maintain, and extend
• Comfortable collaborating with product, design, and non-technical stakeholders

• 📱 Long-term mobile or web product development
• 🧩 Ongoing feature development & system evolution
• 🛠 Refactoring and stabilizing mature codebases
• 🚀 Early-stage products that need a strong technical foundation
• 🏢 Teams looking for a reliable senior engineer, not just short-term execution

• Long-term thinking over shortcuts
• Clean and understandable code
• Sustainable development pace
• Honest timelines and expectations
• Treating products as long-term responsibilities
