role: Senior Software Engineer · Full Stack
employer: Singularis Ventures · Aula # Jun 2025 → present
prior: Axel Technologies / Workpex # Aug 2023 → Jun 2025
focus: [microservices, realtime, CQRS, PaaS, integrations]
stack: [Go, TypeScript, NestJS, Node.js, React, Next.js,
PostgreSQL, Redis, Kafka, RabbitMQ, Docker, AWS]
impact: Workpex load time 30s → 6s (~80%); enterprise WhatsApp + FB Lead APIs
status: open_to_opportunities=true
site: https://musavirchukkan.inI design backends that stay correct under pressure — CQRS hot paths, realtime gateways, multi-tenant SaaS, and self-hosted control planes — then wire them to product UIs that operators can actually use.

| Domain | What I'm shipping |
|---|---|
| Hot-path systems | URL redirect engines, bid loops, WebSocket fan-out — isolate spike traffic from management APIs |
| Control planes | Agent/Hub PaaS patterns (outbound WSS, least-privilege Docker) |
| Product backends | NestJS / Express / Fastify services with Prisma/Drizzle, Redis, queues |
| AI pipelines | Whisper → LLaMA quiz generation; browser-side Gemini/OpenAI analysis |
| Integrations | WhatsApp Cloud API, Facebook Lead API, Twilio, Razorpay, SES |
| Ops | Docker Compose, dual-VPS GitHub Actions deploys, Cloudflare edge |

▸ Expand: design defaults
- Split hot paths from management planes (ClickIt-style CQRS) so viral traffic can't sink billing/auth
- Agents dial out — no Docker socket on the control plane (Wharf trust model)
- Idempotent consumers + DLQs; Redis idempotency on payment webhooks
- Multi-tenant isolation as a first-class invariant (DocAssist clinic boundaries)
- Contract-first APIs (OpenAPI) + typed TS clients when possible
- Observability: structured logs, request IDs, Sentry by service
Curated from musavirchukkan.in/projects. Portfolio write-ups for private work; GitHub where public.
|
Distributed URL shortener for high-concurrency redirects. CQRS planes isolate the redirect hot path; Kafka buffers click analytics; Redis/Mongo serve read models. OpenAPI + Docker Compose ops story.
|
Self-hosted PaaS control plane. Go Agents own Docker on each VPS; NestJS Hub holds desired state over outbound WebSockets; React UI operates projects without mounting the Docker socket on the hub.
|
|
Realtime car auction bidding under concurrent load — JWT-secured WebSockets, Prisma/Postgres, Redis live state, RabbitMQ async bid/notification pipeline.
|
Productized print-on-demand for BRUT — API + storefront + Sharp/BullMQ worker. Money in paise, Redis webhook idempotency, Cloudflare R2 uploads, Shiprocket shipping.
|
|
Multi-tenant clinic SaaS with strict patient isolation, multi-device JWT sessions, cross-clinic conflict detection, dual-VPS GitHub Actions deploys.
|
AI pipeline: lecture upload → Bull/Redis jobs → Whisper transcription → Ollama LLaMA MCQs → streamed progress to user/admin portals.
|
|
Job-application tracker extension: scrape LinkedIn/Indeed → AI resume match score → save structured Notion entries. Keys & data stay in-browser.
|
Relationship-aware expense tracker across API, web, and React Native — JWT, Zod validation, S3 receipts, shared spending charts.

▸ Reliability checklist I run before ship
[ ] hot path isolated from management / billing planes
[ ] request timeouts + circuit breakers on external I/O
[ ] idempotency keys on payment / create / webhook handlers
[ ] queue retries + DLQ + alert on poison messages
[ ] authz on every mutating route (not just authn)
[ ] tenant / clinic isolation verified with negative tests
[ ] migration rollback + backward-compatible schema changes
[ ] load test hot path (p95 / error budget) before go-live
