What Technical Skills Does Toni Specialize In?
Toni specializes in backend development, cloud-native architecture, DevOps automation, and AI/LLM integration. His tech stack covers the full spectrum of modern software engineering, with particular depth in Go, Java (Spring Boot, Quarkus), and TypeScript/Node.js for backend systems.
Backend Development
Toni specializes in backend engineering with Go (90%) and Java with Spring Boot and Quarkus (85%), building production systems across fintech, telco, and insurance domains since 2016. Experience includes stock trading platform maintenance at BCA Sekuritas, loyalty API development for a telco client, and full-stack backend architecture for SaaS products.
Cloud Architecture (AWS)
With 85% proficiency in AWS, Toni designs and implements cloud-native architectures using EC2, RDS, S3, CloudFront, ECS, Lambda, and API Gateway. As a former AWS Authorized Instructor (2022–2025), he has trained over 200 professionals in cloud architecture best practices. Active certifications include Solutions Architect Associate and Cloud Practitioner, with 5 AWS certifications achieved in total.
DevOps & Automation
Toni sets up CI/CD pipelines using GitHub Actions, GitLab CI/CD, and Jenkins, containerization with Docker and Kubernetes, and infrastructure-as-code with Terraform and Ansible. He has implemented deployment automation across multiple client projects, consistently moving teams from manual release processes to automated pipelines.
AI & LLM Integration
Since 2024, Toni has focused on AI integration — building autonomous AI agents, OpenAI API-powered applications, and LLM-based SaaS products. His MFunnel platform demonstrates end-to-end AI product development from model integration to production deployment on AWS serverless infrastructure.
What Services Does Toni Offer in 2026?
As of 2026, Toni offers three enterprise-grade solutions focused on reducing cloud costs, improving system performance, and automating engineering operations. Engagements are scoped for mid-market and enterprise teams — not commodity work. Pricing starts at $800 USD for assessments and scales to monthly retainers for ongoing partnerships.
Cloud Cost Optimization — Starting $800 USD
A structured AWS FinOps engagement covering architecture review, right-sizing, reserved capacity planning, and orphaned resource cleanup. Past work includes cloud cost reduction for an insurance platform through environment scheduling and compute rightsizing. Delivered as a standalone audit report or combined with hands-on implementation. Ideal for engineering teams spending $5,000–$100,000+/month on AWS with no formal cost governance process.
High-Performance Backend Engineering — Starting $2,000 USD
Backend systems in Go and Java built for production — greenfield API development, microservices architecture, performance audits, and bottleneck remediation. Experience spans stock trading platform maintenance at BCA Sekuritas, loyalty API development for a telco client, and full-stack SaaS backend at MFunnel.
DevOps Automation Retainer — Starting $1,200 USD/month
Ongoing DevOps engineering covering CI/CD pipelines (GitHub Actions, GitLab CI/CD, Jenkins), infrastructure-as-code with Terraform, container orchestration with Docker and Kubernetes, and observability stack setup. Teams consistently move from manual, error-prone release processes to automated pipelines. Available as one-time setup engagements or monthly retainers.
What Results Has Toni Delivered?
Across 10+ years and 40+ completed projects, Toni has delivered consistent outcomes for clients across fintech, telco, insurance, e-commerce, and SaaS.
- Cloud cost: Estimated significant reduction through stopping development environments outside working hours and rightsizing compute for an insurance platform
- Deployment speed: Multiple clients moved from manual release processes to automated CI/CD pipelines, reducing deployment overhead substantially
- Reliability: Contributed to a production system with high uptime as part of an integration team
- Training: 200+ professionals trained in AWS cloud architecture as former Authorized Instructor (2022–2025)
- Breadth: Stock trading platform maintenance at BCA Sekuritas, loyalty API for telco client, insurance backend, and end-to-end SaaS at MFunnel
"The key to building scalable systems isn't adding more servers — it's designing the right boundaries between services from day one. Most scaling problems are architecture problems in disguise."
— Toni Kusnandar, reflecting on 10+ years of production backend systems
Why Choose Toni Over Other Freelance Developers?
Four factors differentiate Toni from typical senior engineers or consultants in the market: cloud credentials with real teaching experience, a diverse production track record, full-cycle delivery capability, and honest scoping.
- Former AWS Authorized Instructor (2022–2025): Taught cloud architecture to 200+ engineers — which means Toni can communicate technical decisions clearly to both engineers and non-technical stakeholders.
- Production across domains: Fintech (BCA Sekuritas), telco, insurance, e-commerce, and SaaS — different constraints, different scaling patterns, all real production work.
- Full-cycle delivery: Architecture → implementation → deployment → monitoring → cost optimization. No need to coordinate between a backend contractor, a DevOps consultant, and a cloud architect separately.
- Honest engagement: Scope is agreed before contract. If something isn't the right fit, you'll hear it in the discovery call — not after delivery.
