Open to new roles and consulting
Sangwin Gawande Front-End Architect · Technical Lead · SRE · Problem Solver
I design front-end architecture, lead engineering teams and solve the hard problems in between: legacy migrations, platform and CI/CD setup, site reliability (SRE), production bug fixes and incident RCA. AI tools like Claude Code, Gemini and Copilot are built into how I deliver, with the same review and testing standards as everything else.

About
Architecture, delivery and production, owned end to end.
11+ years building and operating enterprise web and mobile platforms across telecom, FMCG and marketing technology.
I'm currently Technical Lead and L2 Support Lead across two client programmes, owning architecture and delivery while staying hands-on in React, Redux and Node.js. My recent focus is production engineering: SRE monitoring, performance profiling, root cause analysis and customer-impact analysis.
I run teams on clear code-review standards, automated test coverage and documented playbooks, and I use AI tooling (Claude Code, Gemini, GitHub Copilot) for code conversion, test generation and repetitive refactoring.
Engineering practices
Technical skills
- Analysis, design, development, testing and long-term maintenance of applications.
- Front-end team leadership: sprint planning, design reviews and code reviews.
- AEM for content management, with an eye on performance and user experience.
- Angular CLI, ReactJS, Webpack and building modular libraries.
- Sass and Less for styling that stays easy to maintain.
- Tuning code to improve Real User Monitoring (RUM) and Lighthouse scores.
- Translating designs into interactive prototypes and production components.
- Working directly with clients and agencies on requirements and ongoing support.
- UX basics, accessibility and Progressive Web Apps (PWAs).
Client communication
Direct requirement gathering and technical discussions with clients, partner agencies and business owners.
Cross-functional delivery
Day-to-day coordination with DevOps, QA, infrastructure and product teams on design, release risk and production issues.
Project experience
E-commerce, online bidding and CRM applications, delivered in Agile/Scrum teams.
What I do
Architecture expertise
Migration architecture for large legacy codebases, plus the platform around it: monorepo layout, source-control standards, CI/CD, GCP deployment and release strategy, documented as migration playbooks.
Modernisation Strategy
Estate-wide migration planning: dependency upgrades, functional parity checks, test coverage and production validation, tracked through playbooks and CI/CD migration reports.
Platform & DevOps
Repository standards (branching strategy, access control, workflows), GitHub Actions CI/CD, deployments to GCP Cloud Run and related services, canary releases and feature-flag rollouts.
Performance & Reliability
Bottleneck analysis, page-load and build-time optimisation, Lighthouse and RUM metrics. Response times held under 3 s, with RCA and SLA-driven incident management.
Quality & Governance
Code-review standards and development practices backed by Jest, React Testing Library, Playwright and SonarQube.
Multi-Site & Global Delivery
Multi-country, multi-language platforms on AEM SaaS with shared accessibility and SEO standards across markets.
Site Reliability (SRE) & Production Support
I lead L2 production support: watching app health and logs, triaging incidents, fixing live bugs quickly, and running root cause analysis so the same problem doesn't come back. Releases go out behind canary deployments and feature flags, and we keep to our SLAs.

Currently growing
Going beyond the front end with Claude Code
I'm using Claude Code to get stronger on the back end (Node.js, NestJS, APIs, databases) and the DevOps side (GitHub Actions, Docker, cloud deployments). It helps me read unfamiliar code, try ideas quickly and learn while I build, so I can own more of the stack, not just the UI.
