Craft & Systems Architecture
I build commercial WordPress plugins and SaaS backends as a backend developer at Codewing Solutions, and ship serverless side projects like Attic and NEPSE Alert.
Backend Developer · 4+ yrs
Across commercial WordPress suites.
Credited contributions to WordPress open source core.
Custom webhooks, idempotency, Stripe, Square & PayPal.
Sub-15ms serverless financial cron pipelines.
Most WordPress cleanup plugins delete straight away. Attic quarantines instead: it fixes Site Health's autoloaded-options warning and clears out the options, tables, cron events and transients that deleted plugins leave behind. Every finding shows its evidence, and anything removed can be restored in one click for 30 days.
A market assistant built for the Nepal Stock Exchange. Operates entirely inside Cloudflare's serverless free tier with zero monthly infrastructure cost. Cron jobs poll watched stocks every 5 minutes during market hours, calculate technical indicators (SMA, RSI, MACD) at end of day, and send price alerts via a Telegram bot.
Commercial Suite Architecture
Core backend maintenance and feature architecture powering over 24,000 active websites. Engineered dynamic trip booking flows, Gutenberg block schema generators, dynamic currency conversion, and TogetherAI/ChatGPT integration pipelines for automated recipe generation and content parsing.
A multi-tenant transaction routing engine reconciling international payment processors (Stripe, PayPal, Square, Paystack, Flutterwave) under a single uniform interface. Architected on NestJS microservices with PostgreSQL persistence, robust webhook signature verification, and automated retry mechanisms.
Deep experience in the WordPress codebase: hooks lifecycle, Object Cache optimizations, transients handling, custom database tables, and High-Performance Order Storage (HPOS).
Architecting lean, low-latency microservices that offload heavy computations to Cloudflare Workers, V8 isolates, and global serverless databases.
Handling financial events where silent failures are intolerable: idempotent webhook pipelines, reconciliation logs, signature verification, and multi-currency exchange.
Formally credited in official global release notes. Work targeted query safety, REST API reliability under load, and developer-facing component testing.
Formal training in relational database normalization, data structures, network socket programming, and modular system design in Kathmandu.
Attic audits your WordPress database for orphaned options, ghost cron events, stranded transients, and leftover tables — then quarantines them instead of dropping them, so nothing breaks.
How I used Cloudflare Workers, D1, and Cron Triggers to run a live NEPSE alert engine — Telegram bot, portfolio tracking, and a technical screener — with no servers to maintain and no monthly bill.
NEPSE has no public API and doesn't love being polled. Here's how I use Cloudflare Cron Triggers aligned to market hours to fetch data efficiently — without IP blocks or runaway CPU.
I am available for high-impact consulting engagements, code audits for enterprise WordPress plugins, edge microservice design, or senior backend architectural roles.
