A B2B SaaS company grew from 5 to 50 engineers over 18 months. The deployment infrastructure did not scale with the team - by the time they engaged us, deploys were blocking multiple teams and the monolith was starting to split into services.
A digital health platform had a pending enterprise contract contingent on HIPAA attestation. Their AWS infrastructure had no audit logging, PHI was stored without encryption at the application layer, and secrets were in environment variables in plaintext.
A fast-growing e-commerce platform was spending $28,000/month on AWS with no reserved capacity, oversized instances, and a NAT Gateway processing 4TB of data monthly. A 3-week cost audit cut the bill in half.
A Series A B2B SaaS company raised $6M and needed production-grade infrastructure before an enterprise pilot with a Fortune 500 customer. They had a Rails monolith on a single Heroku dyno and 8 weeks before the pilot.
A 400K-user online learning platform had no application monitoring beyond uptime checks. They discovered a critical performance regression when student complaints spiked - three days after it started. We built a full observability stack in three weeks.
An insurance distribution platform needed SOC 2 Type II to close enterprise carrier partnerships. Their AWS infrastructure had the right components but no audit trail, no change management process, and no documented security controls. We got them certified in 6 months.
A mobile game studio was preparing for a global launch expected to spike to 2 million concurrent players. Their backend - a Go API on fixed EC2 instances - had failed a 200K user load test two months before launch. We rebuilt the scaling layer in 5 weeks.
A logistics software company with 85 enterprise customers ran everything in a co-located data centre with a lease expiring in 12 weeks. We migrated 14 services to AWS without missing a single customer SLA.
A digital media company serving 8M monthly readers was paying $23,000/month in CDN costs and still seeing P95 page loads above 4 seconds in Southeast Asia and Africa. A 2-week infrastructure audit identified the root causes of both problems and fixed them simultaneously.
A clinical-stage biotech company needed a validated data pipeline for processing trial results before submitting to the FDA. Their existing pipeline was a mix of Python scripts and Excel files with no audit trail. We rebuilt it with full 21 CFR Part 11 compliance in 10 weeks.
A 120-engineer B2B SaaS company had a 4-person platform team fielding 60+ Slack requests per week from product engineers for environment provisioning, secrets access, and deployment debugging. We built an internal developer platform (IDP) that eliminated 80% of those requests.
A payments processing company had a regulatory requirement for a 15-minute RTO and 5-minute RPO after a regional AWS outage. Their architecture ran entirely in us-east-1 with no DR capability. We designed and implemented an active-passive multi-region setup in 6 weeks.
A 250K-patient digital health platform was operating a 6-year-old Rails monolith. Feature velocity had dropped 70% in 18 months as the codebase grew too large for the team to modify safely. We extracted four critical services over 12 weeks while the product team continued shipping.
A two-person pre-seed startup had a working product but was running it on a personal laptop during demos. They needed a production deployment before a fundraising pitch in 3 weeks. We built a lean, investor-ready infrastructure stack for $400/month.
A two-year-old property management SaaS had a Django monolith deployed manually via SSH to a single GCP VM. The CTO was the only person who knew the deployment process. Any absence created a production risk. We built a full CI/CD pipeline with zero-downtime deploys in 10 days.
A workforce management SaaS had been running Jenkins on a dedicated EC2 instance since 2019. Build times had grown to 3.5 hours for the main application. Engineers had stopped running the full suite locally. We migrated to GitHub Actions with parallelised test execution and cut CI time by 91%.
A DeFi data aggregator serving 400 trading firms through a REST and WebSocket API had experienced three outages in four months, each lasting 40–90 minutes. Their infrastructure was two EC2 instances behind a load balancer with no auto-recovery. We rebuilt it on EKS with multi-AZ deployment, circuit breakers, and automated failover.
A contract intelligence platform processing confidential legal documents for law firms had lost two enterprise deals because they could not demonstrate ISO 27001 certification. The certification was achievable - they had a reasonably secure AWS setup - but the ISMS documentation, risk register, and control evidence were missing entirely. We got them certified in 7 months.
A marketing automation platform with 3,000 B2B customers was running its entire production stack on docker-compose on two EC2 instances. As they signed larger enterprise customers, the architecture became the primary obstacle to uptime guarantees and SOC2 discussions. We migrated to EKS in 4 weeks.
A document intelligence startup was serving OCR and NLP models from a single A100 instance via a Flask app in a tmux session. P99 latency was 8.4 seconds, the instance cost $14,000/month, and a single bad request could crash the model server. We rebuilt the inference layer on EKS with vLLM, request batching, and autoscaling - cutting latency by 78% and cost by 60%.
A flight price prediction startup had built their GCP infrastructure entirely through the console over 18 months. Spinning up a new environment took 2 days of manual configuration. The infrastructure had never been documented. A new CTO joining from Airbnb made IaC a day-one priority. We wrote the Terraform that described what they had, then cleaned it up.
A retail analytics SaaS company had watched their AWS bill grow from $8K to $22K/month over two years without a corresponding growth in customers or revenue. A structured cost audit identified $11K/month in waste across five categories. The fix took 6 weeks and required no application code changes.
A threat intelligence platform needed to meet enterprise customer requirements for network segmentation, mTLS between all services, and zero standing access to production systems. Their flat EKS network allowed any pod to talk to any other pod. We implemented a full Zero Trust architecture using Istio and AWS IAM roles for service accounts in 5 weeks.
A carbon accounting platform was ingesting IoT sensor data from 12,000 industrial facilities via batch CSV uploads processed nightly. Data latency meant enterprise customers could not act on emissions data until 24 hours after the fact. We redesigned the pipeline as a real-time streaming architecture on GCP, reducing data latency from 24 hours to under 90 seconds.
