Banking Partner Integration

• →Led end-to-end integration of a new banking partner (FirstBank Ghana) for GHS virtual account issuance, replacing the incumbent provider with zero disruption; shipped across 4 PRs with staged rollout.
• →Built a polling-based deposit reconciliation service for a partner with no webhook support, and resolved a multi-stage TLS/certificate incident (expired cert, SAN mismatch, untrusted CA) blocking go-live.
• →Diagnosed and resolved 5+ live integration defects (idempotency-key collisions, data-shape bugs, undocumented required fields) through direct partner API testing.

Production Incident Response

• →Root-caused a production payout bug (floating-point balance comparison causing false insufficient-balance failures) in a NestJS/TypeScript backend; shipped fix with regression tests.
• →Diagnosed customer-impacting payment incidents via AWS CloudWatch request-level tracing, including a misrouted £200 GBP payment resolved with a third-party banking provider.
• →Traced a cross-currency KYB verification bug and a stalled third-party KYC check to their true root causes, avoiding incorrect escalation.

Platform & Compliance

• →Extended a public REST API with new KYC fields and shipped a fix unblocking USD virtual account issuance for sub-customers same-day.
• →Currently building a SEC Ghana VAMSS-compliant surveillance endpoint, a compulsory regulatory requirement for Ghanaian fintechs.

Support

• →Serve as support engineer for API clients: onboarding calls, Intercom triage, staging-to-production unblocking.

Performance & Reliability

• →Led the production rollout of a reports-service architecture overhaul, replacing a per-report Kubernetes Job execution model with a persistent worker pool (Java/Spring, Redis-backed), cutting report generation time from ~10 minutes to ~8 seconds; resolved database migration conflicts and CI pipeline blockers that were gating the release.
• →Independently diagnosed and resolved a cascading multi-system outage on a customer-facing demo environment (masked DB security misconfig, ~3-month/1,600+ commit deployment drift, frontend build defect, Kubernetes ingress misrouting, broken legacy-to-modern data sync), unblocking a time-critical sales campaign the same day.
• →Recovered 34,000+ records of inaccessible operational data by tracing a legacy PostgreSQL path, and designed a live two-way Change-Data-Capture pipeline after flagging a data-consistency risk.

Infrastructure Cost Reduction

• →Drove consolidation of QA/nonprod test environments from 8 separate environments down to a single shared Kubernetes (KIND) host, targeting the ~$19k/month nonprod AWS spend.
• →Built supporting infrastructure end-to-end: Terraform-provisioned EC2/KIND host, SSM-based remote ops, IAM wiring for ECR/Secrets Manager, ingress-nginx + VPN routing, and an S3-staged Helm render/apply pipeline.
• →Wired the new shared environment into existing Prometheus/Loki/Grafana observability and shipped a dedicated environment-health dashboard.

Platform & Multi-Tenant Operations

• →Migrated tenant frontends to a CloudFront-backed CDN architecture (external-dns + version-cookie based routing) across dozens of production tenants.
• →Rebuilt Slack alerting across prod and nonprod Alertmanager, consolidating fragmented notification routing into a single on-call channel.
• →Supported UAT02, the platform QA uses to validate new service versions before tenant rollout.

Tooling, Automation & On-Call

• →Built reusable operator CLI tools (tenant feature-flag management, tenant access provisioning, legacy-CDC enrollment), replacing one-off manual SQL fixes with idempotent, re-runnable scripts.
• →Served as weekly on-call engineer (24-hour Thursday rotation), triaging and resolving production incidents across the platform.

Buyback & Burn Bot — Token Economics Automation

• →Built automated STRD buyback and burn system processing auctions every 10 minutes via Kubernetes CronJob, burning ~5.3M STRD yearly.
• →Implemented optimal swap routing algorithm integrating Osmosis Swap Router API with multi-pool routes and slippage protection.
• →Engineered multi-chain architecture handling IBC transfers with Skip API routing, PFM detection, and 2-hop fallback for non-PFM chains.

Stride DEX Subgraph — Uniswap V3 Analytics

• →Adapted Uniswap V3 subgraph for Stride Swap DEX, implementing concentrated liquidity visualization with dynamic tick range histograms.
• →Built complete testing infrastructure with Matchstick framework, achieving full unit + integration test coverage on localnet.
• →Deployed to Goldsky, saving $3,600/month vs The Graph Protocol hosted service.

stBGT Points Program Indexer — Berachain Integration

• →Architected production-grade FastAPI service for real-time metrics, user analytics, and high-throughput API endpoints on Berachain.
• →Built data pipeline with efficient caching strategies, automated daily indexing jobs, and PostgreSQL backends for high-volume transaction processing.

Production Trading Bots — Berachain Ecosystem

• →Developed POL Swapper integrating Ooga Booga DEX aggregator for token-to-stBGT conversions (6-hour K8s CronJob cadence).
• →Built boost cycle operator for validator rebalancing with Merkle proof verification and slashbot for real-time validator slash detection.

Infrastructure & Cost Optimization

• →Reduced GCP costs ~$5k/month by consolidating 16 microservices into 8 deployable services (50% reduction).
• →Migrated TEE bot database from JSON files to PostgreSQL, built Kubernetes orchestration with Helm charts.
• →Modernized protocol testing by converting legacy shell scripts to TypeScript with Cosmos-native client SDKs.

Platform Engineering

• →Architected and deployed cloud infrastructure on GCP using Terraform, building IaC pipelines from scratch for a greenfield crypto product.
• →Built internal tooling and automation scripts in Bash and Python to streamline developer workflows and reduce manual operations.
• →Set up monitoring and alerting systems with Prometheus and Grafana, giving engineers visibility into system health and anomalous behavior.

Product Development

• →Led a team of engineers building crypto-native applications: blockchain oracles, banking integrations, and P2P trading — from scratch to first 2000 users.
• →Built critical backend APIs and smart contracts for on-chain functionality.

Backend Development & Infrastructure

• →Developed and maintained backend services using Python (Flask) and Go for EJable.com tech content platform.
• →Built RESTful APIs and content management systems with efficient database queries and caching strategies.
• →Managed AWS infrastructure (EC2, Lambda, S3) with CI/CD pipelines and automated deployment workflows.

Technical Leadership & Content

• →Trained and mentored junior engineers on backend development, API design, and cloud infrastructure.
• →Authored 12+ comprehensive technical articles on cloud computing, security, blockchain, and DevOps.
