Architecture
Data first, pixels second
Schemas, contracts and boundaries come before components. Get those right and features stop fighting each other.
Full Stack Developer — Bengaluru, India
Backend depth,frontendfinish.
I’m Vaibhav, a full stack developer, who crafts web and mobile products where design and code work as one. I enjoy taking the lead on projects because, honestly, someone has to.
How I build
Approach
I care most about the parts of software nobody screenshots: the schema that survives its tenth tenant, the cache that keeps a dashboard honest, the retry that outlasts a vendor outage. Then I make the surface feel effortless, because the surface is all your users ever meet.
Four rules I don’t break.
The principles behind every system I’ve shipped, from the first schema to the on-call rota.
- Reliability
Make failure boring
Idempotent jobs, outboxes, rate limits and tests on every push. Incidents should be non-events, not war stories.
- Delivery
Small, sharp, measured
Small PRs, honest reviews and outcomes you can graph. Momentum is a feature, and so is knowing it worked.
- AI
AI as leverage
LLMs belong where they remove real toil, with typed tools, guardrails and a human approving every action.
Experience
Seven years of keeping production calm.
From hand-coding client sites to leading architecture for five live SaaS products, still close to the code at every step.

Lead Software Engineer
@ Screen Interactiv
I own architecture, code review and delivery for five SaaS products in production, from a multi-tenant CRM to an embeddable AI chatbot.
- Architected a schema-per-tenant CRM on FastAPI and PostgreSQL with configurable pipelines, custom fields, RBAC and a complete audit trail.
- Shipped an embeddable AI chatbot that answers from each tenant’s own documents, streams replies over WebSockets and drops captured leads straight into the CRM.
- Hardened it with API keys, domain allow-lists and Redis rate limiting, and tracked LLM spend per tenant.
- Took the heaviest dashboard query off the request path with a scope-aware Redis cache that Celery Beat refreshes every 60 seconds.
- Built an AI assistant on async SQLAlchemy that manages tasks through typed tools, with a human confirming every action.
- Synced a real-estate channel-partner portal with Zoho CRM through a retry-safe outbox that rides out vendor outages.
- Backed everything with 325 automated tests, 28 end-to-end tests, and sign-in protected by TOTP MFA and WebAuthn passkeys.

Software Engineer
@ Assent Global
I built and tuned SaaS products and their APIs, with a focus on response times and database load.
- Built REST and GraphQL APIs on Node.js and Express, cutting response times by 20%.
- Cut PostgreSQL query time by 35% by reworking slow queries and their indexes.
- Put a Redis cache in front of the primary database to speed up hot reads.
- Moved reports and notifications onto Celery background workers.
- Profiled and load-tested services to find where the time actually went.
