The Challenge

An industrial distribution company was managing their entire inventory operation through paper registers, Excel sheets, and WhatsApp forwards. Purchase orders were raised manually, delivery challans were handwritten, and returnable items had no reliable tracking — leading to disputes, lost stock, and billing errors.

They needed a single platform that could handle the full document lifecycle of an industrial business: from raising a purchase order to issuing challans, tracking returnables, and generating GST-compliant invoices — all while keeping inventory counts accurate and synced in real time.

Our Approach

We began with a thorough analysis of the client's business workflow — mapping every touchpoint from supplier to warehouse to customer. This research phase was critical: by deeply understanding the industry's document flow before writing a single line of code, we avoided costly rework and delivered a solution that felt purpose-built rather than generic.

The result was UnitPulse — a cloud-first SaaS product architected around four core document types that mirror how industrial businesses actually operate. Every module was designed to feed into the next, so a purchase order automatically updates stock, a delivery challan draws from live inventory, and a returnable challan creates a pending return that reconciles automatically when goods come back.

Purchase Orders
Raise, approve, and track POs with supplier details, line items, and expected delivery dates — auto-updating stock on receipt.
Delivery Challans
Issue outbound delivery challans against live stock levels. Inventory deducted instantly on dispatch with full audit trail.
Returnable Challans
Track items sent on returnable basis with pending return status, due dates, and automatic reconciliation when goods are received back.
GST Invoicing
Generate GST-compliant invoices directly from challan data — CGST, SGST, IGST auto-calculated with printable PDF output.
Cloud Inventory
All stock levels maintained in the cloud with real-time sync, role-based access, automated daily backups, and zero data loss guarantee.
Secure & Backed Up
Encrypted data storage, daily automated backups, and role-based permissions — so only the right people see the right data.

Results

UnitPulse went from requirement gathering to a fully functional, deployed product in under one week — a testament to the efficiency that comes from deep pre-build analysis. The client immediately eliminated paper-based workflows, reduced billing errors to zero, and gained complete visibility into their stock at any point in time.

The returnable challan module alone recovered over a dozen unreconciled items in the first month that had previously been written off as losses. Invoicing time dropped from hours of manual entry to minutes of one-click generation.

"We went from paper challans to a fully digital system in one week. The team understood our industry immediately — it felt like they'd worked in warehousing before."

The Challenge

The client needed a production-grade crypto payment gateway capable of monitoring deposits across multiple blockchains simultaneously, processing withdrawals reliably, and managing thousands of HD wallet addresses — all without relying on a third-party custodian.

Existing open-source solutions were either chain-specific, poorly maintained, or not designed for the reliability requirements of a live payments platform. We needed to build from scratch in Go.

Our Approach

We architected a microservices system where each blockchain has a dedicated Go service — deposit monitor, withdrawal processor, and sweeper — communicating via RabbitMQ. Each service uses signature-based checkpointing to resume from exactly where it left off after restarts.

Multi-Chain Architecture
Independent services per chain (BSC, Solana, Ethereum, Algorand) with shared asset master.
Event-Driven Processing
RabbitMQ with dead-letter queues, retry logic, and routing key separation per service.
HD Wallet Management
BIP-44 derived addresses, threshold-based auto-sweeping to cold storage wallets.
Checkpoint Resumption
Signature/block-based pagination so no transaction is missed after a service restart.

Results

The platform went live processing real transactions within 8 weeks. Fund sweeping reduced manual wallet management overhead by over 90%, and the RabbitMQ-based architecture gave the ops team full visibility into every transaction event.

"The architecture Josh designed gave us something we didn't expect — total confidence in our infrastructure. Every edge case was handled."

The Challenge

A Web3 startup needed a complete fundraising mechanism on BSC — a BNB-based token sale contract with tiered discounts, hard cap protection, and a separate vesting system that would automatically release tokens to investors and team members over a configurable schedule.

The contracts had to be gas-optimized, auditable, and tested with a full Foundry suite before mainnet deployment.

Our Approach

We built three contracts: the ERC-20 token, the ICO sale contract (with phase-based discount mechanics and emergency pause), and the vesting contract (configurable cliff, linear daily release, multi-beneficiary). Each was developed test-first using Foundry with fuzz testing on critical parameters.

Foundry Test Suite
100+ unit tests and fuzz tests covering edge cases, reentrancy, and overflow scenarios.
Discount Tiers
Time-based or volume-based discount phases configurable by the contract owner.
Cliff + Linear Vesting
Configurable cliff period followed by pro-rata daily token release per beneficiary.
Emergency Controls
Pause/unpause mechanics and owner-withdrawable BNB with access control.

Results

Contracts deployed successfully to BSC mainnet and Sepolia testnet. The Foundry suite caught two critical edge cases pre-deployment. The client's team was able to manage the ICO parameters independently through the owner functions post-handoff.

The Challenge

A non-profit organisation wanted to accept cryptocurrency donations from a global audience while providing donors with verifiable, on-chain proof of how funds were allocated — a trust-first requirement for NGO fundraising.

They needed support for 100+ cryptocurrencies, a familiar checkout experience (not just MetaMask), and a smart contract that enforced allocation transparency for donors and auditors.

Our Approach

We built a Go backend orchestrating two payment processor APIs (CoinGate and NowPayments) with webhook handling, idempotent transaction recording, and a BSC-deployed PaymentVault Solidity contract that logs donation allocations immutably on-chain.

Donors could pay with any major cryptocurrency via a clean hosted checkout, while the NGO dashboard showed both off-chain payment records and on-chain vault state in real time.

Dual Payment Processor
CoinGate + NowPayments with automatic failover and 100+ cryptocurrency support.
PaymentVault Contract
On-chain allocation logging — donors can verify fund destination through BSCScan.
Webhook Idempotency
Duplicate-safe webhook processing with idempotency keys and transaction state machine.
NGO Dashboard
Real-time view of off-chain payments and on-chain vault state for fund managers.

Results

HUMA launched with full support for 100+ cryptocurrencies and immediate on-chain transparency for every donation. The PaymentVault contract gave the NGO a verifiable audit trail that they used in donor communications to demonstrate accountability.
