Everything you need to ship clean, scalable APIs.
- [How I Turned a 100 ms Problem into a Microsecond Query with AI-Assisted Performance Engineering](https://akemara.com/en/blog/ai-assisted-performance-engineering/index.md): A real Hungarian-lottery problem, two complete solutions with the actual Go on the table, and the honest story of how AI helped collapse latency from a 100 ms budget to ~1.5 microseconds — not in one prompt, but one disciplined iteration at a time.
- [Goodbye Random Inserts: UUIDv7 vs ULID vs UUIDv4 — Unique Identifiers, Performance, and Database Impact](https://akemara.com/en/blog/uuidv7-ulid-uuidv4/index.md): Random UUIDv4 primary keys quietly double your table size and wreck insert performance. How time-ordered IDs — ULID and the new UUIDv7 standard — fix fragmentation, cache locality, and disk I/O.
- [Zero Trust vs. Traditional VPNs: The Future of Perimeterless Secure Access](https://akemara.com/en/blog/zero-trust-vs-vpn/index.md): The castle-and-moat era is over: there is no moat left to defend. Why the VPN's implicit-trust model breaks in a cloud-first world, and how Zero Trust Network Access (ZTNA) replaces it — with Cloudflare and Microsoft architectures as working examples.
- [A Production-Grade Guide to Golang Database Connection Management with MySQL/MariaDB](https://akemara.com/en/blog/golang-database-connection-management/index.md): Your sql.DB is a pool, not a connection — and treating it wrong leaks connections, hangs services, and triggers Error 1040. A production guide to pool tuning, transactions, prepared statements, and the golden rule of defer rows.Close().
- [AI Agents in Software Development: Navigating the Skies of Modern Coding](https://akemara.com/en/blog/ai-agents-software-development/index.md): Coding is switching from visual flight to instrument flight. How AI agents — wired together by the A2A and MCP protocols — become co-pilots in software development, and why the human stays pilot-in-command.
- [The CTO’s Role in Data Management and Governance: Building a Future-Proof Foundation](https://akemara.com/en/blog/cto-data-management-governance/index.md): Data is a fintech's greatest asset — until it becomes its biggest liability. How a CTO builds the data strategy, infrastructure, and governance that keep it on the right side of that line.
- [The Role of Artificial Intelligence (AI) in Fintech](https://akemara.com/en/blog/ai-in-fintech/index.md): AI in finance is racing past $20 billion — and it's not hype. A CTO's field guide to where AI actually works in fintech: fraud detection, robo-advisors, credit scoring, chatbots, and the governance it all depends on.
- [Macroservices (Mini-Services): Filling The Gap Between Monoliths and Microservices](https://akemara.com/en/blog/macroservices-mini-services/index.md): Not every team needs Netflix-scale microservices — and monoliths stop scaling long before that. Macroservices (mini-services) are the middle path: domain-sized services, fewer moving parts, real modularity.
- [Monolithic vs SOA vs Microservices Architecture: Choosing the Right Approach for a Fintech Startup](https://akemara.com/en/blog/monolithic-soa-microservices/index.md): Monolith, SOA, or microservices? A CTO's decision guide for fintech startups — with concrete numbers for team size, transaction volume, and infrastructure cost at each stage of growth.

A practical tour of local and global scope in Go — shadowing pitfalls, cross-package globals, getters, and sync.Once — with runnable examples.
- [Mastering the Linux column Command: A Comprehensive Guide with Examples](https://akemara.com/en/blog/linux-column-command/index.md): Stop squinting at misaligned terminal output. The often-overlooked column command turns messy text into clean tables — with headers, hidden columns, reordering, even JSON — in a single pipe.
- [How To Become One Of The Top 1% Software Engineers](https://akemara.com/en/blog/top-1-percent-software-engineer/index.md): Coding skill gets you into the room — it doesn't make you the person everyone turns to. Eight habits that separate the top 1% of software engineers: ambiguity, initiative, expertise, customer focus, simplicity, community, business sense, and culture.
