Primary track

Backend & Systems

Durable execution, change-data capture, and crypto-infra indexing: Go, PostgreSQL, failure scenes, and proof.

Selected projects

DurableGo read-only operations dashboard showing execution totals, active leases and failure scenes

DurableGo

Backend & Systems · Durable workflow engine in Go

PostgreSQL-backed durable workflow engine with lease/fencing semantics and idempotent starts. Failure scenes SIGKILL workers mid-execution and prove stale completions are rejected (409) through the API.

RelayDB pipeline: source PostgreSQL WAL via pgoutput into capture, persisted with fenced checkpoints, then API, dashboard and webhook delivery

RelayDB

Backend & Systems · PostgreSQL CDC platform in Go

Change-data-capture from the Postgres WAL: pgoutput decoding with TOAST awareness, idempotent replay per source transaction, and fenced LSN checkpoints proven by crash-replay testcontainers suites.

ChainForge operator dashboard showing a labeled demo snapshot of reorg-safe indexing and delivery

ChainForge

Backend & Systems · Reorg-safe Ethereum event indexing

Canonical-chain tracking with reorg detection, common-ancestor recovery, and HMAC webhook delivery. Finalized blocks are never silently rewritten.

DurableMCP dashboard showing execution totals, crash-rate chart, recovery events and a live executions table

DurableMCP

Backend & Systems · Durable execution for MCP tool calls

MCP server where every tool call is persisted before dispatch, executed under fencing-token leases, and inspectable from Postgres. The hosted demo kills its own executor to generate genuine crash-recovery events.

Founding Engineer

Remote

  • Building PaySaathi end-to-end as the first engineer across Flutter, Supabase, PostgreSQL, Edge Functions, Next.js admin tooling, Tally connector paths, integrations, and production infrastructure
  • Rebuilt standalone accounting surfaces across app and backend: voucher-family schemas, register RPCs, bill-wise settlements, ageing/analytics, financial statements, journal/note/FY flows, and line-money contracts
  • Shipped production workflows for GRN/Receipt Note, stock journals, purchase/credit/debit note lines, GST return exports, e-invoice/e-way bill enablement, invoice PDFs, and WhatsApp delivery
  • Hardened access and operations through RBAC/voucher-type grants, tenant-write guards, license/feature gates, partner tier controls, assisted onboarding, and admin wallet/payment reconciliation
  • Improved sync performance and reliability: statement-level rewrite of hot sales-invoice aggregate triggers, fresh-before-retry tally job claiming, per-company sync status in the Tally loader, and hardened auth/payment boundaries
