About

Engineering background & product focus

Professional Background

I'm a frontend-focused full stack engineer with 2+ years of experience building customer-facing SaaS products in startup teams, focusing on landing-page builders, CRM platforms, and campaign & workflow automation.

My engineering approach connects visual craft with solid full-stack architecture. At Brand Exponents, I contributed across Swipe Pages and Swipe One, building visual workflow builders, multi-channel marketing campaigns, shared integration layers across several providers, and platform stability systems through major launch periods.

Currently, I'm building toward AI product engineering and developer tools in public by shipping streamed multi-agent PR analysis systems, cited web-search engines, and AST-driven localization tools while publishing technical walkthroughs on dev.to.

Product & Workflow UI

Crafting responsive builder canvases, template discovery libraries, and guided automation flows for non-technical users.

Swipe PagesSwipe One CRMReact / Next.js

Full-Stack & Async Systems

Developing REST APIs, message queues (BullMQ/RabbitMQ), webhooks, and reusable multi-provider integration engines.

Node.js / ExpressMongoDB / RedisSeveral Providers

AI Interfaces & DevTools

Engineering multi-agent code analysis, streamed AI interfaces, cited answer retrieval, and autonomous AST code transforms.

Brand Exponents Creatives Pvt LtdSwipe Pages · Swipe One

Oct 2023 – Aug 2025

Integrations
Contributed to the Workflow Builder's integration layer on Swipe Pages: shared configuration, property selection, field-mapping, and auto-matching patterns reused across several providers, including SendFox, ActiveCampaign, AWeber, Moosend, Salesflare, and EngageBay.
CRM
Helped build Swipe One's CRM features, including contacts, leads, contact properties, and email & WhatsApp campaigns, and contributed to redesigning the workflow builder from blank-canvas drag-and-drop into a guided, template-led flow.
AI-assisted features
Contributed to AI-assisted features including natural-language workflow generation, an AI assistant that auto-configures workflow nodes and auto-drafts email nodes from the user's profile context, and the original Swipe Genie guided page-generation experience.
Workflow builder & analytics
Contributed to workflow-related dashboards and reusable workflow templates on Swipe Pages, and helped build the Swipe One workflow-templates dashboard and workflow analytics so users could discover templates and monitor automation performance. Also contributed to shared page-builder systems including global responsive typography, named solid and gradient colour systems, and a responsive video module across landing pages and funnels.
Platform, launches & reliability
Worked with background jobs, queues, and webhooks; contributed to the shared Template Library; built a reusable infinite-pagination system used across four product surfaces; and helped keep production stable through launches and debugging. Participated in two AppSumo launch periods, resolving customer queries, fixing live issues, shipping hotfixes, and iterating on product feedback across Discord, Facebook, and AppSumo.

Now

Current Focus

I develop new capabilities by turning what I learn into complete working systems — then writing about the decisions that shaped how they work.

Building

An agent-governed lesson pipeline that turns raw technical course material into rigorously evaluated, interactive HTML lessons — enforced by versioned prompt contracts, append-only evidence records, and a six-audit adversarial gate before anything releases. Read the case study →

Shipping

I’m turning recurring engineering problems into small, reusable tools and shipping them for others to use — most recently server-active-indicator, built to solve a UX problem I kept encountering across my own free-tier projects. It ships with a 5-state lifecycle, adaptive backoff, a React adapter, and zero runtime dependencies.· npm · v0.3.2 · MIT

EXPLORING

I'm continuously deepening my AI and software-engineering practice by using frontier models, coding agents, and AI-assisted development tools in my day-to-day workflow — from brainstorming and system design to implementation, debugging, and iteration. I experiment with different models and approaches, learning where they add real value and where careful engineering judgment still matters.
