About

Senior Software Engineer with a frontend core and strong product delivery experience.

I am a Senior Software Engineer with 5+ years of commercial experience building and stabilizing production web and mobile products.

My core is frontend engineering with React, Next.js, TypeScript, and modern JavaScript, but I also work across mobile delivery, backend integration, release flows, and AI-assisted product work when end-to-end execution is needed.

Who I am

Most of my work is in real products with existing codebases, complex UI, and long-term delivery needs. I am strongest where teams need clear frontend architecture, reliable execution, and code that remains maintainable as the system grows.

I have a strong frontend core with React, Next.js, TypeScript and modern JavaScript, and I also work well with AI-heavy or AI-generated projects: assessing code quality, finding structural risks, supporting ongoing development, and refactoring unstable areas into production-ready systems.

Strong frontend core

Most of my work is product-facing engineering built with React, Next.js, TypeScript and modern JavaScript.

Cross-platform delivery

I work across web, mobile, integrations, and release flows when the product needs end-to-end execution.

AI codebase recovery

I can assess AI-generated code, find risky structure, support delivery, and refactor unstable areas into maintainable systems.

Frontend architecture

I design React and Next.js systems around clear boundaries, predictable state, and code that stays easy to extend.

  • Clear feature boundaries, reusable UI primitives and maintainable component structure.
  • Data flow shaped for real product complexity, not only happy-path demos.

Mobile development

I build and improve React Native products for iOS and Android, from shared TypeScript logic to release-ready flows.

  • Cross-platform product delivery with attention to device-specific behavior and performance.
  • Comfortable with release readiness, app stability and long-term support.

AI project analysis and refactoring

I review AI-generated codebases, identify structural risks, and turn unstable implementations into maintainable product systems.

  • Codebase audit, targeted support, and focused refactoring instead of blind cleanup.
  • Comfortable restoring structure while keeping delivery moving toward production.

Integrations and product systems

I work confidently across APIs, auth, payments, realtime flows, maps, monitoring, and release processes.

  • REST and GraphQL integration with realistic contracts, failure states, and rollout concerns.
  • Comfortable wiring product UI into the systems that make it work in production.

How I work

The main idea is simple: make the code easier to change, not just faster to ship. I prefer explicit boundaries, predictable data flow, and practical architecture over clever abstractions.

Architecture and maintainability

I prefer explicit boundaries, focused responsibilities and predictable data flow over clever abstractions.

  • Clean architecture for me means clarity, not ceremony.
  • I avoid local fixes that make the system harder to evolve later.

Complex product UI

I am most useful on non-trivial interfaces: dashboards, onboarding, forms, maps, subscriptions, and realtime surfaces.

  • I care about state ownership, edge cases and UI logic staying manageable.
  • The goal is not just shipping screens, but shipping stable product behavior.

Performance and accessibility

Performance and accessibility are part of implementation, not cleanup tasks for later.

  • I think about rendering cost, perceived speed, semantics, keyboard flow and clarity while building.
  • Good UX depends on engineering decisions, not only visual design.

Team collaboration

I work closely with designers, backend engineers and product teams to keep decisions concrete and implementable.

  • With designers, I focus on states, edge cases, responsiveness and interaction quality.
  • With backend engineers, I focus on contracts, failure states, and realistic data flow.

Next step

I am a good fit for teams that need a Senior Software Engineer who can build strong frontend systems, ship across web and mobile, and bring structure to AI-generated or fast-moving product codebases without overcomplicating them.
