14 years engineering production frontend systems.
8+ years specialising in Angular at scale.
Currently consulting from Bengaluru.
My work focuses on micro-frontend architecture, performance engineering, and the UI platform layer — the parts of an application that make sustained, multi-team product development possible. I’ve shipped systems used by tens of thousands of pharmacies, decomposed a four-year monolith without freezing the business, and built a clinical platform end-to-end on my own.
Previously at Halodoc, Indonesia’s largest health-tech platform, where I led the micro-frontend migration of a four-year Angular monolith, owned production infrastructure for the public website, and mentored engineers from junior to mid-level.
Currently consulting independently — taking on end-to-end product builds and providing architecture and technical advisory for engineering teams.
From idea to production system — architecture, implementation, deployment, and ongoing operation. Working solo or embedded with your team. Suited to startups validating new products, established companies launching new initiatives, and clinics or businesses digitising paper-based workflows.
Senior engineering judgment for teams already in motion — frontend architecture decisions, monolith decomposition strategy, performance audits, technical code reviews, and direction on hard engineering calls. Engagement can be project-scoped or fractional.
Decomposing a four-year Angular monolith.
Halodoc’s internal operations console — used across pharmacy delivery, tele-consultation, insurance, and labs — had grown over four years into an Angular monolith. Build times of 20–30 minutes, slow release cycles, and multiple teams blocking each other on a single codebase.
I evaluated four micro-frontend approaches through structured analysis and proof-of-concept, then chose Reverse Composition based on the application’s specific constraints: internal use, no SEO or SSR requirements, and Angular framework limitations around shared runtimes. We migrated incrementally using the Strangler Fig pattern — starting with low-risk modules, validating in production, iterating, then expanding.
Result: Build times dropped from 20–30 minutes to 5–8 minutes. Twelve micro-frontends in production. Independent team velocity restored. Zero feature freezes during migration.

An Ayurvedic clinic in Gokarna with 13,000+ historical patient records had no digital workflow — clinical notes, prescriptions, and patient history all on paper. I built a complete clinic management system from architecture through deployment, working solo across the full stack.
Nx monorepo with Angular 21 (Signals, Standalone Components) on the frontend and NestJS 11 with PostgreSQL on the backend. Multi-role RBAC for Staff, Doctor, and Admin. Patient registration with webcam capture. Nadi Pariksha (Ayurvedic pulse analysis) workflow. Prescription transcription. Bilingual English/Kannada PDF generation. Shared TypeScript libraries for API contracts and Material 3 theming.
Result: Currently in active clinical use, deployed on AWS LightSail behind a NetBird WireGuard VPN mesh. All 13,000+ historical patient records digitised and queryable.
Building and scaling Halodoc’s pharmacy supply network. Led a team of four engineers.
v1.0 — Built Medisend from scratch for 14,000+ Indonesian pharmacies. Custom 3-layer state architecture (presentation → CartFacade → CartState), OTP-based onboarding, role-based routing across admin, seller, and buyer journeys, catalog management, order processing, KYC verification, and credit-limit based payments.
v2.0 — Led the merger of Halodoc’s existing Portal Apotek into Medisend, eliminating a manual activation bottleneck that previously required sales teams to make multiple in-person visits per pharmacy. Built self-service registration across four pharmacy types with role-based homepages.
Result: Sales teams freed from manual activation work. Platform serves the Indonesian pharmacy network end-to-end across both buyer and seller journeys.
