Blockchain Developer Case Studies

Real outcomes from clients who hired blockchain developers through CodeMiners.

Series B SaaS startup (US)

B2B SaaS

Challenge

The in-house Blockchain team was overwhelmed after a major product pivot. They needed two senior engineers immediately to stabilize the platform and ship a new billing module before the next funding milestone.

Solution

CodeMiners placed two senior Blockchain engineers within 48 hours. They joined the client's GitHub, attended daily standups, and shipped the billing module in 5 weeks alongside existing team members.

Result

2× engineering velocity, billing module launched on schedule, $1.2M ARR milestone hit within 3 months.

E-commerce retailer (UK)

E-Commerce

Challenge

Peak season was approaching and the client's Blockchain frontend was underperforming — 4-second load times causing a 32% cart abandonment rate on mobile.

Solution

A CodeMiners Blockchain specialist audited the codebase, identified render-blocking assets and unoptimized data-fetching patterns, and rebuilt critical pages with performance-first architecture over 6 weeks.

Result

Load time reduced to 1.1 seconds. Cart abandonment dropped 18%. Revenue per session improved 24% during peak season.

Digital health startup (Canada)

HealthTech

Challenge

The team needed to build a HIPAA-compliant patient portal and integrate it with an existing EHR system in under 3 months, with a limited budget that ruled out hiring locally in Toronto.

Solution

CodeMiners deployed a Blockchain lead engineer plus one mid-level developer. They designed the portal architecture, built HIPAA-compliant data flows, and integrated the EHR API — all while the client's internal team focused on clinical features.

Result

Portal launched in 11 weeks, under budget by 28%. HIPAA audit passed first attempt. 3,000+ patients onboarded in month one.
