Sawal Timsina

I’m a backend-leaning full-stack engineer and team manager with 5+ years building scalable, fault-tolerant Go services that power job-seeker, scheduling, e-signature, regional-tourism, and notification platforms for the Japanese market.

I’m the principal author of my company’s internal Go clean-architecture starter (go-gin-skeleton), which now underpins 7+ production services org-wide. I’ve led the Backend Division in TDD adoption and scaled engineering process from the Management Board—driving measurable reliability and latency gains.

My core stack spans Go (Gin, GORM, uber-go/fx, swag), TypeScript (NestJS), React/Next.js dashboards, and Flutter mobile apps, deployed across GCP services like Cloud Run and Firebase. I also drive data-driven reliability using Looker Studio, Crashlytics + Sentry, structured logging, and CircleCI post-deploy health checks.

Recently, I’ve expanded into AI/LLM product engineering—designing two-stage prompt pipelines with tool/function calling, fine-tuned model integration, and embedding-based semantic search (RAG-adjacent) for production agents and AI-assisted workflows. I balance shipping enterprise-grade backends with strong engineering discipline, code review at scale (2,800+ PRs), and mentorship through standardized, consistent practices.
