About TonSoft
TONSOFT is a software consultancy founded by a Senior Software Engineer with 8+ years of experience building high-availability, cloud-native systems at Amazon Web Services and Tamara Finance.
We specialize in legacy modernization, microservices architecture, and high-availability system design for startups and scaleups — particularly in fintech and other transaction-heavy domains where downtime is costly.
Our founder previously designed billing infrastructure at AWS processing over 1 million requests per second at 99.995% availability, led a project spanning 50+ global teams that cut new-region launch time by 110x, and delivered a cost-optimization initiative saving $10M annually. At Tamara Finance, he led the migration of a core BNPL platform from a legacy monolith to distributed microservices, raising availability from 83% to 99.9%.
TONSOFT brings that same production-grade engineering discipline — rigorous architecture decisions, fault-tolerant design, and measurable outcomes — to every client engagement. We work with international clients across time zones, combining strong English communication with cost-effective delivery from Sri Lanka.
