Application Modernization & Stabilisation

We are seeking an experienced Solution Architect (Freelance / Contract) to analyze the current environment of our client’s mobile and web applications, identify critical issues, propose architectural improvements, and lead the execution of stabilization and modernization initiatives. The architect will act as a key technical advisor, ensuring the platform is stable, scalable, and future-ready, while resolving ongoing client issues.

Review existing DevOps practices, CI / CD pipelines, and infrastructure deployments.

Solution Design & Recommendations

Propose short-term fixes for critical business-impacting issues (e.g., app stability, OTP removal, pricing bugs). Design a scalable, modular architecture roadmap (microservices, containerization, Kubernetes).

Recommend best practices in logging, monitoring, automated testing, and deployment.

Execution & Implementation

Guide and oversee the implementation of stabilization fixes (driver app offline, OTP flow, rider-driver connectivity). Lead code restructuring, error logging, and testing framework introduction.

Oversee Kubernetes deployment, CI / CD pipeline enhancement, and DevOps standardization.

Client & Team Enablement

Proven experience as a Solution Architect in mobile and web application modernization projects.

Strong expertise in Node.js, TypeScript, Flutter, React / Vue, MongoDB, and cloud-native architectures. Hands-on experience with Docker, Kubernetes (K8s), and CI / CD pipelines (GitHub Actions / GitLab).

Strong background in DevOps, SRE practices, and system reliability engineering

Experience in stabilizing monolithic applications and guiding migrations to modular / microservice architectures. Solid understanding of logging, monitoring (Datadog / ELK), and automated testing frameworks.

Strong problem-solving skills to resolve issues without introducing regressions.

Excellent communication and client-facing skills.

Nice to Have

Experience with NestJS, PostgreSQL, and microservices migration (Strangler Fig pattern). Familiarity with ride-hailing, logistics, or real-time location-based apps.
